Microsoft Sentinel Reviews

My role thus far has been to integrate security log sources into the platform. This includes developing or troubleshooting some of the data connectors for different sources, such as web application firewall interfaces.

Sentinel is a SOAR platform. It represents the next generation beyond traditional SIM and SIEM platforms. Its powerful SOAR functionality orchestrates and automates responses to security events, eliminating the need for manual intervention. Instead of relying on human analysts to monitor events and react, Microsoft Sentinel leverages pre-defined automation rules. These rules correlate relevant events, generating a holistic understanding of the situation. Based on this analysis, automated responses are triggered, expediting the resolution process and eliminating any delays associated with manual identification and decision-making.

Sentinel provides us with a unified set of tools for detecting, investigating, and responding to incidents. This centralized approach offers both advantages and challenges. On the one hand, it grants us the flexibility to tailor Sentinel's capabilities to various situations. However, this flexibility demands a deep understanding of the environments and activities we're dealing with to effectively utilize Sentinel's features. While this presents a challenge, it also highlights the potential benefits of this unified approach. The unified view is important to me because I get all the information together in a single pane of glass instead of having to switch between multiple applications. The ability to consolidate all of that information into a single application or dashboard and to centrally evaluate its intelligence is a significant advantage.

Sentinel's ability to secure our cloud environment is of the utmost importance.

Sentinel Cloud Protection offers a collection of customizable content that caters to our specific requirements, demonstrating the solution's flexibility. The versatility of this content allows us to address a wide range of needs. However, in most instances, we need to adapt the material to suit our unique circumstances. While Sentinel Cloud Protection provides a comprehensive set of resources, including pre-written responses, it often requires tailoring to fit specific situations. This customization process is not a drawback but rather an essential aspect of effectively utilizing the tool. It's crucial to understand the nuances of each situation to apply the content appropriately. While I wouldn't consider this a negative aspect, I've encountered individuals who believe they can purchase a solution, implement it without modification, and achieve optimal results. However, such unrealistic expectations often lead to disappointment.

The Sentinel Content Hub is essentially the central repository where we acquire the content to build upon. Therefore, it serves as the starting point for our efforts. Some of the hunt rules have been quite beneficial in terms of what they provide from the Content Hub, allowing for a plug-and-play approach. This means we can immediately benefit from what's available without having to do any additional work. We can then build upon this foundation and extend the capabilities beyond what's provided by the Content Hub. The Content Hub itself is a valuable asset that gives us a head start in achieving our objectives.

Content Hub helps us centralize out-of-the-box SIM content. This has made our workload more manageable.

The ability to correlate and centralize all of that information together, rather than having to manage it across multiple platforms and potentially miss things between different platforms, makes it more likely that we will not miss anything. The workload and the missed threats that we need to respond to have been reduced because of that unified approach. The mean time to detect has been reduced, and the mean time to respond has been reduced.

Sentinel correlates signals from first- and third-party sources into a single, high-confidence incident. The third-party integrations provided through Microsoft offer all the tools we need to integrate those sources. In other cases, we have to build the integrations from the ground up. Currently, we are struggling to integrate some of the sources that don't have existing connectors. However, the platform is flexible enough to allow us to build these integrations. It is just a matter of finding the time to address this issue.

Our security team's overall efficiency has improved. The build phase is still ongoing. We have not yet fully transitioned to an operational model. We are still in the build implementation stage because we need to integrate some third-party sources into the existing platform and ensure that they are included in the scope of the analytics rules. However, this has significantly reduced the amount of time spent working between different platforms.

The automation capabilities are perhaps the platform's most significant advantage. The force multiplier capability is exceptional. Traditional SIM or SIEM-like platforms were effective in gathering and presenting security information to security personnel. However, security personnel were still responsible for evaluating the information and determining whether a response was necessary. One of the benefits of Sentinel's automation capabilities is the ability to automatically trigger an action or response activity, which is a significant advantage.

The automation capabilities have helped reduce our mean time to respond. Automated events can prevent a problem from escalating beyond a single incident to multiple occurrences before we have to respond to it. In this way, automation effectively catches problems right away.

Sentinel has helped to improve our visibility into user and network behavior. This is extremely important because it allows us to have a better understanding of how users and networks are behaving.

Sentinel has helped reduce our team's time.

Sentinel has streamlined our event investigation process by eliminating the need to manually track down specific event activities. The rules are now automatically identifying and processing these activities, significantly reducing the time required for investigation. Tasks that previously took half an hour can now be completed in under five minutes.

The analytic rule is the most valuable feature. It allows us to assess the various use cases we've developed and then automate those processes accordingly. I consider it a force multiplier. It empowers a small team to achieve a significant impact, whereas previously, I would have relied on multiple individuals. By utilizing it, we can accomplish more with fewer resources.

While I appreciate the UI itself and the vast amount of information available on the platform, I'm finding the overall user experience to be frustrating due to frequent disconnections and the requirement to repeatedly re-authenticate. Microsoft needs to address these usability issues to enhance the user experience.

I have been using Microsoft Sentinel for seven months.

The stability is exceptionally reliable. I tend to be quite vocal when things don't function as expected. The web interface requires using a browser for interaction, and I often find myself multitasking between Sentinel-related tasks and other activities, such as responding to emails. When I return to the Sentinel interface, I'm prompted to re-enter my credentials, which causes me to lose my previous work. If I'm using KQL to query data, I frequently have to restart my work from scratch. This can be frustrating, but I've learned to copy my work periodically to avoid losing it. I haven't encountered this issue with previous platforms, even those that use web interfaces.

Sentinel boasts exceptional scalability. While it's crucial to monitor data ingestion costs, Microsoft has effectively crafted a platform capable of expanding to accommodate far greater volumes than initially anticipated.

The technical support has room for improvement.

Neutral

The initial deployment was straightforward. Our strategy was to consolidate onto a common platform. We have a significant portion of our security information being handled through SysLog events. As a result, it was almost as straightforward as simply rerouting data from the old platform to the new one. This served as a preliminary test of the new platform to ensure it was functioning as intended and could effectively redirect and handle the increased volume.

The deployment likely involved six people, but not all at the same time. There were six people involved in the deployment overall, but we probably had four people working on it at any given time. From a headcount perspective, I believe four people is the appropriate number.

We employed a third-party company for the implementation because we sought expertise in Sentinel and the Azure platform, and we aimed to augment our existing staff.

We have achieved a positive return on our investment. In my previous jobs of comparable size, I would have needed approximately three people to manage the event activity and to handle and respond to it. Here, we can accomplish this with two people. As a result, we have saved at least one headcount with our current staffing levels. Additionally, as we expand the platform, we will not need to increase the headcount to manage the growth.

Microsoft Sentinel can be costly, particularly for data management. While Microsoft provides various free offerings to attract users, these benefits can quickly become overwhelmed by escalating data management expenses if proper precautions are not taken.

I don't think it's Microsoft engaging in underhanded tactics. I believe the issue lies with customers not paying close enough attention to what they're enabling. Initially, they're excited and eager to incorporate everything, but before they realize it, they've incurred unexpected costs.

Azure Monitor Log Analytics and Sentinel have different subscription plans and pricing tiers. This segmentation was implemented to accommodate the distinct business relationships within our organization. Sentinel costs are managed separately from Azure costs.

The decision to adopt Microsoft Sentinel was made before I joined the organization. I understand that they evaluated all the major solutions available, including Splunk and QRadar. However, due to the selection of a cloud-based solution, they opted for Microsoft Sentinel as it aligned with their overall strategy.

I would rate Microsoft Sentinel eight out of ten.

We've got a user base globally of about 5,000 people.

Microsoft Sentinel does require maintenance, which includes monitoring the incoming data and ensuring that everything is functioning as expected. While automation simplifies many tasks, it doesn't eliminate the need for oversight. We still need to verify that everything is working correctly. Part of the maintenance cycle involves ensuring that the automation agents are operational and performing their intended tasks and that events are being collected and evaluated properly.

Users need to have a clear understanding of their goals before selecting a solution. I have encountered too many people who believe that simply choosing a solution will resolve all of their problems. It is crucial to understand the desired outcome and the specific requirements of the use case to determine whether or not Sentinel is the appropriate fit.

Our two primary uses for the solution are incident management and threat hunting. We use Sentinel and other Microsoft security products for security investigations, threat, team, and incident management purposes. The tool is deployed across multiple departments and locations, with around 8,000 total end users.

We use multiple Microsoft security products, the full Defender suite including Defender for Cloud, Cloud Apps, and Identity, all integrated with Sentinel. 

Integrating multiple solutions is straightforward; as they are all Microsoft products, it's easy for Sentinel to ingest the logs and data connectors. The process is very simple, and we can configure log sources or data connectors in Sentinel in a couple of clicks.  

As a next-generation AI-powered SIEM and SOAR tool, Sentinel provides an all-encompassing cyber defense at the cloud scale. The solution's machine learning capabilities make threat hunting and identification rapid across the entire cloud environment.

The solution provides excellent visibility into threats; it's integrated with Microsoft's threat intelligence platform, which forwards information to Sentinel. We have robust threat detection 24/7.   

Sentinel helps us prioritize threats across our enterprise, an essential function that lets us focus on investigating and resolving high-priority incidents first. When the most significant threats are dealt with, we can move on to the medium and low-priority issues.  

The multiple Microsoft solutions work natively together to deliver coordinated detection and response across our environment; they work very well together, and we trust these products to investigate matters further. 

The Microsoft solutions provide comprehensive threat protection across our entire organization.  

Sentinel enables us to ingest data from our entire ecosystem, which is crucial to our security operation. We require the data not just from Microsoft products but also from different firewalls and other security products, including firewall proxies, web proxies, logs, etc. We can quickly integrate multiple data sources in just a few steps. 

The solution's threat intelligence helps prepare us for potential threats before they hit and take proactive steps. Sentinel's intelligent and fast threat detection allows us to respond rapidly to critical and high-priority incidents by leveraging built-in automation and orchestration tools. 

Using Sentinel gives us time savings of 30-40%.  

The solution also decreased our time to detect and respond by 30-40%. 

Sentinel is a SIEM and SOAR tool, so its automation is the best feature; we can reduce human interaction, freeing up our human resources.

The built-in AI and machine learning are excellent; they reduce the number of false positives by around 90%.

The centralized threat collection is a valuable feature. 

The solution is cloud-native, so it's faster and easier to deploy as there is no hardware or software to implement.

The product is flexible enough to deploy in the cloud and on-prem, which is an advantage over other SIEM tools.

Sentinel allows us to investigate threats and respond holistically from one place, which is crucial because time management is essential during a security investigation. Having all the relevant data in one place enables security analysts to investigate and resolve quickly.   

The solution's built-in SOAR, UEBA, and threat intelligence capabilities provide comprehensive protection. The SOAR capability is excellent and better than other products on the market, reducing our dependence on security analysts, and IT takes less investigation time. We can leverage the UEBA to focus on risky users and entities first during an investigation, which is an integral part of the process. 

Compared to standalone SIEM and SOAR products, Sentinel reduces infrastructure costs by around 50% due to the cloud and reduced maintenance relative to legacy solutions. Sentinel is also approximately 70% faster to deploy than legacy solutions with the same rules. 

The solution helped to automate routine tasks and the finding of high-value alerts. This reduced our dependency on security analysts and their workloads because the solution reduced false positive alerts by about 90%. This freed up our analysts and is the most significant benefit of automation.  

The product helped eliminate having to look at multiple dashboards and gave us one XDR dashboard, which provides us with greater visibility and a reduced time to investigate and resolve.  

The data connectors for third-party tools could be improved, as some aren't available in Sentinel. They need to be available in the data connector panel. 

The solution could have more favorable pricing; the cost is relatively high compared to other SIEM tools, which can be prohibitive for smaller organizations. 

We've been using the solution for over a year. 

Sentinel is stable. 

The solution is scalable. 

The technical support is good and responsive, but in some cases, it took a long time to resolve our issue.

Positive

We previously used IBM QRadar as a SIEM tool and switched because Sentinel is cloud-native and has more comprehensive capabilities, including SOAR capabilities. Sentinel fits our clients' requirements better, as many of them utilize the MS Defender security suite, which gives them a specific grant for free data ingestion. The solution also provides greater visibility.

I wasn't involved in the solution's initial setup, and in terms of maintenance, it's very lightweight; updates are Microsoft's responsibility, so we don't need to do anything.

Sentinel is expensive relative to other products of the class, so it often isn't affordable for small-scale businesses. However, considering the solution has more extensive capabilities than others, the price is not so high. Pricing is based on GBs of ingested daily data, either by a pay-as-you-go or subscription model.

The product saved us money, but actual savings depend on the project size, as the pricing is per GB of ingested data. Our savings are approximately 40-50%. 

We evaluated various solutions, including LogRhythm SIEM, Splunk, and Sumo Logic Security. We chose Sentinel because it's more advanced, cost-efficient has greater capabilities and fulfills our requirements better than the other products.

I rate Sentinel nine out of ten. 

To a security colleague who says it's better to go with a best-of-breed strategy over a single vendor's security suite, it's better to go with multiple vendors. This provides better visibility and avoids a single point of failure.

My advice to others considering the product is it depends on the project requirements. For larger organizations, I recommend Sentinel, as it's very advanced. However, for smaller-scale industries, Splunk and IBM QRadar are good options. For primarily cloud-based organizations with the majority of users in the cloud, then Sentinel is again an excellent choice.

We use it across multiple platforms to protect against cyber attacks, threats, and vulnerabilities.

We use Sentinel in locations across Europe, India, and other parts of the Asia-Pacific region.

Its inbuilt Kusto Query Language is a valuable feature. It provides the flexibility needed to leverage advanced data analytics rules and policies and enables us to easily navigate all our security events in a single view. It helps any user easily understand the data or any security lags in their data and applications.

Sentinel helps to prioritize threats across our enterprise because it has built-in machine analytics capabilities. It predictively scans security vulnerabilities and threats from our environment using KQL.

We use more than one Microsoft security solution including Microsoft Endpoint Manager and Azure Defender. 

Integrating these solutions is not a hard task; it requires just a few clicks. Microsoft Support Services have helped us customize these integrations as well.

These Microsoft solutions provide good, comprehensive threat protection. Because they integrate well with the other Microsoft solutions we have in place, we have been able to minimize compatibility issues.

Sentinel works perfectly well in terms of ingesting data from our entire ecosystem. This is very important to our organization because we deal with data related to the health, services, and utilities of the general public. It is critical that we protect the data from third-party attackers.

Sentinel perfectly enables us to investigate threats and respond holistically from one place.

We can schedule and define the security rules and policies in Sentinel to easily automate security scanning and threat processing. Since it is managed by Microsoft, we do not have to worry about security updates and patches as well.

Sentinel is capable of providing all of the analytics in a single dashboard and has eliminated the need to look at multiple dashboards. The visualization is great, and you can optimize the dashboard according to your rules and policies. It also provides pie charts and donor charts for all processes showing what the issues are, how many are resolved, how many are traces, etc. The spikes as well as the level of security threats during a particular time period are also shown. Because it is already integrated with Azure Monitor Agent, Sentinel can monitor all events on a real-time basis. Overall, Sentinel is good in terms of analytics and visualizations.

It helps us prepare for potential threats before they hit and take proactive steps. It provides automatic recommendations as well because it has a recommendation engine within the solution. It has artificial intelligence and machine learning capabilities and can predict security threats in a uniform way. It alerts or notifies you as well. 

Sentinel has decreased our overall time to detection and response by 40 to 45%. Previously, we used on-premises applications and Defender. It took a lot of effort to monitor all threats and perform real-time monitoring of our application's data. Since Sentinel can be connected to various data sources, such as Dynamics 365, Office, SQL, etc., it minimizes the overall time spent and the human effort needed.

In terms of visibility into threats, 95% of the time Sentinel scans well. However, 5% of the time there are problems with filtering out the noise. It is not completely user-friendly in terms of filtering out unwanted issues.

Sentinel's alerts and notifications are not fully optimized for mobile devices. The overall reporting and analytics processes for the end user should also be improved. Also, the compatibility and availability of data sources and reports are not always perfect.

It is fully dependent on Microsoft Azure since it is a part of Microsoft Azure cloud computing. If you use another cloud computing solution like AWS or GCP, then Sentinel will not work perfectly.

I've been using it for more than two years.

It is stable.

It is a scalable solution though it doesn't require scalability if the security and first line of integrations are complete.

I would rate Microsoft's technical support at eight out of ten because they take around two to three days to respond.

Positive

We previously used Splunk. We switched because of compatibility issues with our existing Microsoft solutions such as SQL Server, Power BI, and the other applications hosted on Azure.

The initial deployment is quite easy because everything is on the cloud and is a part of Azure. You just have to integrate this service into your applications, and technical support can help with that.

Sentinel doesn't require any maintenance because it is a managed service. Thus, the security updates and so forth are managed by Microsoft.

We implemented it ourselves. Our team consisted of eight people including members from the DevOps team, security team, and infrastructure team.

The cost of Sentinel is high. It typically costs more than $100 for five to ten users of the licenses or subscriptions. It costs around $123 per day on the cloud. Small- to mid-sized organizations would need a dedicated budget to adopt this solution; however, the cost may not be an issue for large, enterprise-level organizations.

Microsoft should provide free trials, evaluation versions, or demo licenses to users.

There are multiple companies providing similar solutions, and whether you go for a best-of-breed strategy or a single vendor's security suite depends on what matters to you. For us, compatibility with and adaptability to our existing applications were of high priority. Also, Microsoft is a giant in the software space globally, and we trust their solutions.

I would advise any prospective user to analyze their requirements, pricing model, and whether there are other security solutions available within the Microsoft Azure space. Overall, Sentinel is a good solution, and I would rate it at nine out of ten.

We use it for our security operations center. We have private and multi-cloud environments.

It enables data integration within our hybrid, multi-cloud environment, and it makes this data integration very easy for our security operations center.

Sentinel has helped improve our visibility into user and network behavior. It helps in identifying risky users, creating a watch list for specific users and their activities, which is very important.

It has also been saving us time. It's a complete cloud-based solution, so there is no time wasted on setting up servers, infrastructure, et cetera.

It also reduces the work involved in event investigation because it puts together detection logic through detection rules. That helps in automating incident identification.

The features that stand out are the 

• detection engine
• integration with multiple data sources.

And while it does not give the tools to detect and investigate, it provides
the ability to integrate multiple tools together on the platform. This is very important for us. Sentinel provides very good integration with Microsoft Power Apps and Power Automate. That is a very handy feature.

It provides a good user interface for an operations analyst and makes it easy for an ops analyst to do incident analysis and investigations.

One key area that can be improved is by building a strong integration with our XDR platform.

I have been using Microsoft Sentinel for over a year. I'm a product manager, and I do not do hands-on deployment, but I do product definition, platform selection, and product feature definition.

It is a stable product.

The technical support team is good. They have account managers aligned with our customers. It is a good, scalable model.

Neutral

We started with Sentinel only. We have had some experience with Splunk, but Sentinel is more mature, flexible, and scalable.

The install or setup time is very small. Without Sentinel, it would usually take 15 to 30 days to set up a SIEM solution in an environment. With Sentinel, it is very easy. A completely production-grade environment can be set up within a week.

Setting up Sentinel is straightforward. Because it is a cloud-based solution, there is no infrastructure deployment involved. Much of the implementation can be done in automated ways. We leverage that automation for implementation. It doesn't require much staff. It is very automated.

It requires maintenance, and that is part of what we cover by providing our customers with managed services.

Our team does the deployment.

We have seen ROI.

The licensing cost is available on the Microsoft Azure calculator. It depends on the size of the deployment, the size of the data ingestion. It is consumption-based pricing. It is an affordable solution.

We primarily use the solution for analyzing logs, such as those from Azure AD. We have it integrated with Microsoft 365 and plan to integrate it with our firewalls so we can analyze those logs too. So, our main uses are for log analysis and to check for vulnerabilities in our system.

We use more than one Microsoft security product; we also use Defender for Cloud. 

Sentinel helps us to prioritize threats across our enterprise. 

The solution reduced our time to detect and respond. 

The log analysis is excellent; it can predict what can or will happen regarding use patterns and vulnerabilities.

Sentinel provides good visibility into threats. 

The product enables us to investigate threats and respond holistically from one place, and that's important to us. 

Given the solution's built-in SOAR, UEBA, and threat intelligence capabilities, it provides reasonably good comprehensive protection, and we are happy with it. 

Sentinel helps us automate routine tasks and find high-value alerts; the playbooks are beneficial and allow us to optimize automation.

The tool helped eliminate multiple dashboards and gave us one XDR dashboard. Having one dashboard is the reason we purchased Sentinel.  

Sentinel's threat intelligence helps us prepare for potential threats before they hit and to take proactive steps. It helps a lot, and that's another main reason we have the product.  

The solution could be more user-friendly; some query languages are required to operate it.

A welcome improvement would be integrations with more products and connectors. 

We've been using the solution for over a year. 

The solution is stable.

Sentinel is a scalable product. 

Microsoft support is good, I rate them seven out of ten. 

Neutral

We didn't previously use another solution of this type; when we moved to Azure, Sentinel was one of the products Microsoft recommended, so we started using it.

I was involved in the deployment of Sentinel, but my colleague did the majority. The setup was basic; some query language is required to implement it fully, and we could improve our configurations. Our implementation strategy was to cover the major products first, including Office 365 and Azure AD. We did that, and we're now adding the other tools we use in our environment.

Our setup is not particularly expansive, so we can deal with the maintenance requirements within our team; it only requires one team member. Our team consists of three or four admins; we manage the Azure AD logs, and Azure AD has 400 users.

The pricing is reasonable, and we think Sentinel is worth what we pay for it.

One of the main reasons we switched from on-prem to Azure Cloud was to save money, but at the same time, we kept adding on features and spent a lot doing so. We're now looking at cost optimization and removing unnecessary elements, as one of our primary goals is to reduce costs. I'm unsure if we are, but we are trying to get there.

I rate the solution seven out of ten. 

Sentinel allows us to ingest data from our entire ecosystem, though we are attempting to integrate all our products. It can ingest and analyze all the data, but we aren't using this functionality to its fullest extent yet.

My advice to someone considering the product is to use it. Start by integrating your primary applications, then slowly move on to others in descending order of importance. 

We are using Microsoft Sentinel for our traditional SOC. So previously, we had multiple products, like VM products, log analytics products, and analysts. We are making so much effort to analyze incidents and events in the security operation center., after which we decide whether it's an incident or an event, and we take action. After Sentinel's implementation, it would be much better and much simpler. For instance, we can now save much more time since in Sentinel, there is artificial intelligence, so the system will decide for you instead of a human. The system will learn what kind of thing you should take action on, and it will save some time since you do not need much human power. In traditional SOC systems, there were three or four people. But in Sentinel, it's much easier, and you do not need so many people in the SOC. So you will save time and keep it cost-effective.

Previously, we were incurring a huge cost being paid to a person. But in Sentinel, you do not hire anyone because the system provides system insights through the cloud applications. So you do not need to put effort, or you don't need to hire either of the senior people. So in, in your SOC team, would be mid-level people, and it would be fine. Also, you do not need so many people. So, one or two people left the organization after the central implementation. So we just have an agreement with one company at a professional level since they're also managing Sentinel. We do not need to pay for the maintenance of applications. So that's also a benefit for us. So, in this case, we are only paying Sentinel yearly or annual costs.

Previously, we could not do some automation. So in Sentinel, we create some playbooks, and with some features in the playbooks, we have some capabilities. For example, when a virus enters the system, we will take action to keep the system safe. So, the machine with the virus can be automatically isolated from the network, and this might be a pretty cool feature in the solution currently.

Microsoft Sentinel has improved our entire SOC, like our log system and incident response. So we are able to quickly respond to incidents and take action. Even though Microsoft Sentinel has already improved our system, it should further improve for on-premises systems or traditional systems, especially to get or collect logs from the legacy systems. Also, Microsoft should improve Sentinel, considering that from the legacy systems, it cannot collect logs.

I have been using Microsoft Sentinel for about six months. My company has a partnership with Microsoft.

I have not contacted technical support.

We are using Microsoft Intune. From the mobile device management point of view, it makes work very easy. We are just planning that with Microsoft Intune, we can easily export some logs to Sentinel to analyze them. We are not using this feature right now, but we are planning. If you are using Microsoft applications, it's very easy to integrate them with other Microsoft products.

Defender is something that we are using as an antivirus for Android applications, but we are not using it on the cloud.

From a cost point of view, it is not a cheap product. It's, like, an enterprise-level application. So if you compare it with a low-level application, it's expensive, but if you compare it with the same-level application, it's pretty much cost-effective, I think. Because for other products, you need to purchase them by paying thousands of dollars. In Sentinel, you pay for how much you use, or you just pay for how much you consume storage, log interface, or system. It will not be a one-time cost, but it will be like a continuous rental system, where you subscribe to an application, and then you use it. That's very easy. I think the company got the solution for a long time. If you purchase some products, you need to invest in something, and it increases your investment budgeting. Many enterprises do not like investments. But this is not a one-time cost, to be honest, since continuously, we will pay. This is maybe a negative point of view, but considering from company to company, it entirely depends on a company's strategy.

Previously, it was a little bit difficult to find where an incident came from, including which IP address and which country. So in Sentinel, it's very easy to find where the incident came from since we can easily get the information from the dashboard, after which we take action quickly.

Sentinel does provide me with the ability to set priorities on all the threats across your entire enterprise. So, it is very important because we were previously getting the service from the outside. It would be yes. Sentinel is a next-generation SOC. So, Sentinel also still develops some applications on Sentinel's site, so maybe in the next release, they will introduce a much more effective version for the company. I'm not sure how many companies use it right now. Maybe in the future, more companies will use Sentinel because its features are such that compared to the traditional SOC systems, they are not affected since the system is a cloud-based system. So it's easy to manage. Also, you don't need to care about it from an infrastructure point of view. Additionally, we don't need to take care of products, and we don't need to take care of maintenance. From a product point of view, we do not need to manage since we just need to focus on the incident event.

Right now, we are using very traditional applications, so there is no use of native Microsoft applications right now.

Sentinel enables me to ingest or collect data from my entire ecosystem, but not all of them, because some traditional applications cannot provide some data needed for export. It cannot allow you to get reports or logs from outside. It's a challenging point, so this might be an opportunity for us to change the traditional application. In traditional applications, and sometimes in IT systems, it might be very difficult to get data insight. In some cases, we need to change the application since, in traditional applications, you cannot get support. To fix it, you need to decide something, or maybe you need to decide on the application change. It might be an opportunity for you. But in the next-generation application, there is no problem. With a new application, you can easily integrate with Sentinel. In Sentinel, the negative point is just related to cloud applications. With cloud applications, maybe sometimes you cannot get data from the on-prem application. So if you use a cloud system, like Sentinel, which is a cloud system, then it's very easy. If you are using an on-prem system, Microsoft Sentinel sometimes may not be easy to integrate.

Sentinel allows me to investigate threats and respond quickly and thoroughly from just one place. It accelerates our investigation, especially our event investigation and incident investigation. Using Sentinel, we take quick actions and get quick insights after its standard implementation. So it is time-efficient.

Previously, we had no SOAR applications. In Sentinel, if you want to take action quickly, you need to create playbooks so that if something happens, you can just develop an application like a playbook in Sentinel so that if something happens, you can tell Sentinel to take action. You can freely create your own playbooks since it's very easy. In my opinion, this is the best feature of one product. Normally, you need to purchase two applications or two products. But in Sentinel, they combine everything together. This is the most beautiful feature for me.

Sentinel helps automate routine tasks and help automate the finding of high-value alerts. We do not need to create manual operations like when our system engineers see the incident and they do a system analysis. So after Sentinel, the system analysis is not done by anyone since Sentinel can already make decisions and then take action by itself. So at this point, there's no human power. Sometimes human power is needed, but maybe eighty percent or ninety percent of the time, there is no human power needed. So, it has caused significant improvements in our entire company.

Sentinel has helped eliminate having to look at multiple dashboards and giving us just one XDR dashboard. Previously, we had to check multiple dashboards, especially in relation to whether logs were coming and other things, like incidents and events. In Sentinel, you do not need to check many dashboards. So you are just designing one dashboard, and then, on the entire dashboard, you will see everything. So, it now saves time since previously there were multiple dashboards causing our engineers and our analysts to get confused at times. So they used to ask our managers to understand better. Currently, it is very easy to understand since one needs to check in on one dashboard, and there's no confusion among the engineers. But they do not need to ask anyone to understand. Apart from better understanding, it has improved our systems.

From a security point of view, you need to go with multiple vendors, but this is a traditional system. But right now, if you want to create a good security system, you need to implement each product with one vendor. Because vendors currently state that, if you want to have a high-level security system. You need to implement each product on a security level from one vendor. Microsoft-level vendors offer many features, but people only just purchase or use one product, and that's all. It's not good for security infrastructure. So, you need to implement all security products from just one vendor. I think one vendor and the needed security products will be enough for a company. Sentinel is our next-generation SOC. Currently, I don't see any competitors at this level.

I rate the overall solution a nine out of ten.

We're a cybersecurity company using Sentinel to provide SIEM services to our customers. 

Sentinel improved how we investigate incidents. We can create watchlists and update them to align with the latest threat intelligence. The information Microsoft provides enables us to understand thoroughly and improve as we go along. It allows us to provide monthly reports to our clients on their security posture. 

It helps us automate some tasks but not others. There are some things we missed because there aren't any rules. We're still working on integrating it. We know it can detect high-severity incidents if we utilize it correctly. We've been able to automate incident responses to some high-level threats we've encountered.

Microsoft's threat intelligence helped us prepare for attacks by developing rules before they hit. We know what behavior to expect because we have visibility into the threat and the actors. 

Sentinel's reporting features save us time. In the past, we created reports in Microsoft Word by dropping in screenshots. With Sentinel, we can create readymade reports from the dashboard. Our monthly report previously took about 16 to 24 hours to complete. We cut that in half. 

We have our own ticketing system for our soft team, and Sentinel's playbooks helped us automate many processes. 

Sentinel provides excellent visibility. Microsoft updates a lot of its security solutions via Sentinel. The content hub and connectors are available to integrate everything. Microsoft also created separate analytics groups, so we log behaviors and use a template. We often need to modify the template based on a customer's log behavior and our correlation and analysis. 

We can learn some new techniques for using KQL correctly by studying the latest templates that Microsoft releases and creating some KBs for our analysts. The MITRE ATT&CK framework is now integrated into Sentinel, so we can statistically identify which part of our microservices are vulnerable. We can assess the severity of threats and prioritize them accordingly. We also need to prioritize based on our SLAs. 

My company also provides managed service for Defender for Endpoint, previously called ATP. We also work with Defender for Cloud and Defender for Identity.

All the Microsoft solutions are integrated with Sentinel, including 365 apps, Azure AD, and various cloud-based security solutions. It includes all the connectors you need to ingest logs from multiple Microsoft products, giving us near-total visibility. Some customers use on-prem security appliances, so we have to correlate logs. 

Sentinel comes with Azure Lighthouse. We can link the subscription to our customer's tenant and ask them to create a global admin account. We can report on the activities using each account and how secure the credentials are. The integration is seamless when we have that level of access. 

We offer ingestion for all Microsoft products and always recommend our clients get everything so we can get full threat visibility and effectiveness. Having all the products integrated into Sentinel helps us see the big picture. In addition to the analytics rules and everything, we're utilizing dashboards and workbooks. Some workbooks are templates that Microsoft provides, but we also develop our own. 

We can compile all this data, put it in a workbook, and create rules. The other part is communicating with the customer because the user is still reviewing logs. Is it an admin? Is it doing daily counts of logins, etc? 

Three of our customers use Defender for Cloud. If a company needs it, we can support it. We have Microsoft-certified engineers who can provide expert frontline support.

Initially, we were only ingesting incidents from Defender for Endpoint, but now we can ingest more data throughout the system. Previously, we could not see some things. We could do it, but we had to search through the portal to find what we needed. Using a connector, we can see everything our employees do on the endpoint, such as device info, location, logins, etc. It's especially useful when employees work remotely or outside their normal area. 

Sentinel lets us investigate threats and comprehensively respond from one console. We can have multiple tabs on one application. The capabilities are robust and marketable. All of these solutions are combined. 

We've seen delays in getting the logs from third-party solutions and sometimes Microsoft products as well. It would be helpful if Microsoft created a list of the delays. That would make things more transparent for customers. 

In some instances, the customer reports that they suspect malware on a computer, and one of their IT guys noticed it. There is a five to ten minute delay before we can see it and respond. As a security company, we don't want the customer to be the first one to identify the threat. However, we must deal with delays from the various products we're integrating. For example, Apex One has a 15-minute delay.

Sometimes it's an issue with the third-party product, but sometimes it isn't. If it isn't, we need to open a ticket with Microsoft. We would benefit from transparency around delays and communication about what Microsoft is doing to resolve the issue. 

Another issue is transparency around usage and associated costs. There are charges if you use playbooks and queries. If you query 100,000 times a day, your costs will go up. The usage only displays in gigabytes per day. A breakdown would help us make reports for our management. 

We have used Sentinel since 2020, so it has been about three years.

We also have experienced some performance problems in the UK. I'm not sure how that works, but something might be going on in the back-end. We transferred to a different region a while ago and lost some of our workspaces. We were shocked.

If Microsoft needs to failover to another region, the customer should be informed because it affects many things. Some of the products we ingest just suddenly stopped, and we have to redo the integration with Cisco Umbrella, AWS S3, and SendGrid. Azure was pulling those logs, and the connections were suddenly cut when this happened. 

I rate Microsoft's support a five out of ten. We had problems using Azure and getting the logs from event services for one of our customers. The date and time the log generated on our customer's device were wrong. It showed the event's location but not the time that the event was generated. 

We contacted Microsoft, who told us to expect a reply the following day, but they didn't respond until four days later. Then, they sent us to another department to speak with someone more knowledgeable about our issue. 

We described the problem, and they asked us for evidence. They wanted our support team to recreate it. Microsoft's support team can create a lab environment and recreate the scenario for themselves. We had to stop the call because we were too busy.

Neutral

We previously used an in-house SIEM solution. 

Deploying Sentinel was complex initially, but it has gotten easier. We documented how we did everything, so it's easy for someone to replicate the steps. If we have accepted the CSP invite, we can deploy it in two days, including configuring ingestion, creating rules, and Azure onboarding. We also must build dashboards and templates. Sometimes there are delays, and it might take three to five weeks.

Sentinel is costly compared to other solutions, but it's fair. SIEM solutions like CrowdStrike charge based on daily log volume. They generally process a set number of logs for free before they start charging. Microsoft's pricing is clearer. It's free under five gigabytes. Some of these logs we ingest have a cost, so they don't hide it. I believe the tenant pays the price, and Microsoft helps create awareness of the cost.

With other solutions, you don't know what you're being charged until you get the bill. You might find that you're using playbooks or queries too much. Microsoft gives you visibility into your expenses. 

We evaluated a few other solutions, including CrowdStrike, Splunk, and LogRhythm. We decided to go with Sentinel because we have Microsoft-certified staff, and many companies in the UK are adopting Defender and other Microsoft security solutions. Sentinel offers seamless integration with Microsoft security products, and we've also seen how flexible it can be.

We can leverage KQL queries. If you're trying to send logs to another SIEM, you'll probably need an API and a lot of other components to make it work. Sentinel makes our jobs easier by providing all of the connectors and out-of-the-box integration. 

I rate Microsoft Sentinel a nine out of ten. I think the industry is shifting toward a single-vendor strategy instead of best-of-breed. If you have a lot of tools from various vendors, it makes things more complicated. You need to hire employees who specialize in each device. It's better if your team understands a solution's features and capabilities. 

If you're considering a SIEM solution, you should compare each product's mean detection and response time. I'm unsure if that information will be publicly available for every solution, so you may need to test them. You should also think about other components besides cost. Sentinel might be more expensive than other solutions, but it's more comprehensive because it incorporates all the different security elements and keeps evolving.

Microsoft is constantly updating all of its solutions. We mainly utilize Microsoft infrastructure, but some solutions are based on Unix or Linux. At the same time, threats on that side aren't as critical as those from Microsoft. They own the operating system, so they're positioned to understand the vulnerabilities and how to fix them. 

Every day, I log into Microsoft Sentinel to check the logs. I start by checking the incidents and analyzing them. If I need to create an automatic rule, I do so. If the logic needs to be changed, I make the necessary adjustments. I am responsible for managing Microsoft Sentinel for our organization.

For our organization, Microsoft Sentinel helps us prioritize threats across most of our environment because we have not yet fully integrated the solution into all aspects of our operations. Currently, we are working on integrating mutual source AWS into Sentinel, which will provide us with more visibility. Apart from that, there is already a lot of visibility in case of any failures or anyone attempting large deployments across other companies or similar activities. Additionally, if someone attempts to use login information from a different location, it becomes apparent, as it is impossible to travel that quickly. Sentinel covers almost everything.

We are using Microsoft Office 365 for email security in our environment. Our infrastructure engineers have integrated Microsoft Office 365 with Sentinel. When we view the old connectors in the application, it mentions Microsoft Office 365. Currently, it also indicates this in terms of firmware.

Microsoft Sentinel can enable us to ingest data from our entire ecosystem. However, since we are currently receiving services from an external source, we are not integrating the tool right now. That's why we are looking for another tool that we can integrate with Microsoft Sentinel. Once we do that, I believe we will be able to see everything, including any malware-related issues, as well as other security and licensing concerns.

The ingestion of data into our security operations is of utmost importance. If we are not monitoring whether people are sending large documents to other companies, how will we realize it? We don't have any other tool for that. Of course, we have email security and EDR, which cover some aspects, but some of them are not effective or are too basic. Unlike them, Microsoft Sentinel is comprehensive. It records everything: every click, download, login, and search. Therefore, it is a necessary tool for our operations.

Microsoft Sentinel allows us to investigate threats and respond quickly from a unified dashboard. A couple of months ago, there was a concern with the AWS environment, and our director asked us to identify any relevant code-related alerts originating from the environment. Since we didn't have the rules at that time, I looked into the recommended analytics section, which turned out to be quite straightforward. When we write Python or work with any logs, cells, or Java-related elements, Microsoft Sentinel provides us with insights and a logical approach to integrating our environment. During my investigation, I discovered some configurations related to the Python code, and it appears to be functioning well now.

Microsoft Sentinel's built-in SOAR, UEBA, and threat intelligence capabilities work well and are further enhanced with the addition of a firewall for added protection.

Before our organization implemented Microsoft Sentinel, we only had an email security DLP solution and some other tools. While we could see the logs on our computer, they were often presented in a confusing manner, appearing like gibberish to us. However, with the introduction of Sentinel, we can now interpret and make sense of that information.

When I joined the organization, they were already in the process of implementing Microsoft Sentinel. However, I am familiar with other integrations with Sentinel, such as AWS, and the integration is not difficult. We simply create the necessary resources, and everything is well-documented, which is a huge plus. We can access all the information online, both in the AWS part and in Microsoft Sentinel. So, I believe it's not rocket science.

It helps automate routine tasks and aids in identifying high-value alerts. We have automated the tool to receive critical or high alerts and send us messages accordingly. This automation is currently active. Whenever a high alert is generated, it comes through direct messages. Even during non-working hours, I receive these alerts on my phone immediately. If it's an important alert, I can respond promptly. We had an incident where I had to work on weekends due to such an alert. However, if I'm not using the tool or haven't activated it, I generally don't turn on the computer after work hours. So, this feature has been beneficial for us. Some months ago, there was a Microsoft bug that created false positive alerts for every clean link, including company links. We made modifications to the alerts, and now we no longer receive those unnecessary alerts.

It helps eliminate the need to look at multiple dashboards by providing us with just one XDR dashboard. We no longer have to go to other places. However, there are instances when we receive alerts about failing servers, and we can't check them using Sentinel; instead, we have to use Azure Active Directory. It's not Sentinel's fault, and checking through Azure Active Directory is not difficult, but we still have to go somewhere else.

Sentinel's threat intelligence assists us in preparing for potential threats before they strike, allowing us to take necessary precautions. My weekly routine includes dedicating at least two hours to the accounting part. I am constantly searching for any threats in our environment that may have gone unnoticed. So far, I haven't found anything, but I'm always vigilant because we can never be entirely certain that there are no threats.

We have been enabled to save a significant amount of time. The log files consist of hundreds of pages, and to review them, we need to possess networking knowledge to identify the specific case. Without knowing what we are searching for, it's like trying to find a needle in a haystack. Sentinel migrates the logs and presents the visual information in a user-friendly manner, which has proven to be a time-saving solution for us.

Sentinel saves money by reducing the number of people required to monitor the alerts. For example, if there are normally 50 alerts per week, fine-tuning reduces them to just one.

Microsoft Sentinel helps decrease our time to detect and time to resolve. Sentinel provides a brief introduction to the events occurring in the environment when someone is causing instability in the AWS environment. Sentinel precisely identifies the issue and offers a link for accessing more information about the situation.

The dashboard that allows me to view all the incidents is the most valuable feature. Threat hunting is also valuable. Sentinel has a Microsoft framework, so we can experiment with numerous queries. There are almost 500 queries available that we can utilize based on our environment.

I believe one of the challenges I encountered was the absence of live training sessions, even with the option to pay for them. Microsoft insists that all information is available in the documentation, which I must admit is quite comprehensive and helpful. However, for someone without a coding background, learning solely from the documents can be challenging at times. It would be much easier to learn if there were practical exercises and instructional videos available. This aspect bothered me significantly. While I did come across a course, my preference was to access it through Sentinel since they are already providing us with their services. Having the team trained up would undoubtedly streamline my job and save a considerable amount of time.

I have been using Microsoft Sentinel for one year.

We have not had any scalability issues with Microsoft Sentinel.

Microsoft Sentinel is scalable. We can add as many services as we want, and Microsoft automatically increases the capacity by adding memory and storage.

I have used technical support many times. Sometimes, I have a really hard time understanding them. I am not sure if they are calling from India, but there was background noise at times. However, they are really helpful, even though they seem a bit indifferent. They frequently inquire whether we have addressed the issue and if it has been resolved—quite a lot, actually.

In a company, we are often very busy. They expect us to address the issues immediately, but sometimes it can take months. So, I inform them that I will follow up. They can be a little pushy, which is understandable from their perspective, but for us, it can be challenging because we have many other tasks to handle. Sentinel is just one of my priorities, and there are a lot of other things I need to take care of. That's why sometimes we need time, but to their credit, they are always responsive. Whenever we ask them a question, they promptly provide a response.

Positive

I had previously used Kibana, which is quite different from Microsoft Sentinel. When I used Microsoft Sentinel for the first time, I realized that this was the ideal solution. Microsoft Sentinel is user-friendly, unlike Kibana, which I found difficult to install and not very user-friendly. Microsoft Sentinel, on the other hand, is incredibly user-friendly, making it easy for everyone to understand and learn how to use it. It is a straightforward solution to comprehend.

I give Microsoft Sentinel a nine out of ten.

We are currently evaluating Microsoft Defender and CrowdStrike in our environment to determine which one is a better fit. As for Defender, I cannot claim to have a complete understanding of it since it's in a testing environment. I can monitor people's devices, but I have not yet received any alerts generated by the devices. It has only been around ten days.

I am responsible for creating documentation for all of our implementations, while other teams handle the infrastructure portion.

Maintenance is minimal for Microsoft Sentinel. There is a check button in the house. Sometimes I go there because we occasionally find that some things are not working properly. So we have to go there and address the issue, but it is not a common occurrence. Maybe it happens, like, three times a year which is not bad.
