Microsoft Defender for Endpoint Reviews

We use it to protect our servers and endpoints, which include our employees' laptops and our own endpoint portal, where we see the single pane of glass reports. It is our first line of defense.

We have seen improvement in all our endpoint vulnerabilities, which is very crucial for us. If this had not been implemented, we would be in trouble because our endpoints would be unprotected. It has definitely improved the security posture of our organization.

Also, automated investigation, protection, and alerts have affected our security operations in a positive way. We get to see the vulnerabilities quicker, and we get to see the root cause analysis as well.

Defender for Endpoint has also eliminated having to look at multiple dashboards. The Endpoint portal is sufficient. It is easier for our security operations team to look at the vulnerabilities and reports and plan for remediation actions.

In addition, the moment the solution's threat intelligence provides a suspicious IP or a suspicious URL, we block it right away. We are more secure. It has helped our security operations detect things in advance and preempt any vulnerabilities.

We have seen productivity gains in terms of the mean time to resolve issues, on the order of 20 to 30 percent. We have the unified dashboarding and reporting, the investigation, and automated remediation. Saving 20 percent of our time translates to saving money.

The detection features are valuable, as is the fact that it is easier to port these logs into Sentinel. That is also useful for us. It is more comprehensive.

The visibility into threats that Defender for Endpoint provides us with is quite deep and mature. The threats that we find help us understand our vulnerabilities and remediate them if required.

Another very important point is that it prioritizes threats across our enterprise. This is important; the solution is the first line of defense. Defender for Endpoint is very crucial for our defense, considering that we all work remotely.

We also use Defender for Cloud, Purview, and Microsoft Sentinel; all of these are integrated and go into Sentinel. It was easy to integrate them because we are using Azure Cloud, and all of them are native to Azure Cloud. The connectors also make it easy. The fact that these solutions work natively together, providing coordinated detection and response, is very important to us. That is precisely why we got into Azure. This does provide us with a comprehensive view of the threats, incidents, alerts, investigations, and threat-hunting processes. Overall, it gives us multiple ways of securing things.

If the solution could be integrated more with Defender for Cloud, to be more unified, that would help. It is good now, but even more integration could be done with Defender for Cloud. We see two different portals. If Defender for Endpoint could be ported to the CSPM, Defender for Cloud, that would make things even easier for us.

I have been using Microsoft Defender for Endpoint for three years.

We have never had any downtime or any other issues.

We have scaled up to 3,000 endpoints, and there is scope for it to be scaled more. When more employees join or more departments come in, we'll be scaling up.

Defender for Endpoint's technical support is fairly good. We haven't encountered many problems with them. We initially had some problems when we integrated Sentinel, but that was resolved internally.

Positive

We did not have another EDR solution. We started with Azure.

The deployment was straightforward because it's all native. We are integrating within the Azure environment, so it is easy.

This solution specifically would have taken a week or so to deploy, but it was part of our overall deployment along with the other Microsoft products. After a week, we started utilizing or pushing the data into our security operations.

We had multiple servers and laptops that were endpoints to be protected by Defender for Endpoint, almost 3,000 endpoints. We had to go one by one. Initially, we implemented 500, and eventually we built on top of that.

It doesn't require much maintenance unless we add more endpoints. That's when we need to push it. Otherwise, there is not much activity involved.

It was all done in-house and required three full-time resources.

We have easily seen 20 to 30 percent savings, year on year.

They would have definitely evaluated other solutions, but the clear preference for a native solution is what made this stand out.

A single-vendor security suite has its advantages in terms of ease of porting, ease of connecting to the SOC, and also dashboarding. For ease of use, a single vendor strategy is valuable. But cost-wise, if you go for multiple vendors, you may be able to negotiate the cost, but that approach makes things difficult to integrate.

It detects suspicious malware and credential access issues, and it even maps to the Mitre ATT&CK framework. It's a pretty good product. Try it out and implement it as soon as possible.

We use it as an antivirus and EDR solution. We also use it for vulnerability scanning and threat hunting.

It is cloud-based. We have a cloud-first strategy when it comes to our organization.

We are a very small, lightweight start-up organization who has only been around for a couple of years. We have 17 endpoints. 

We have it deployed on our endpoints and virtual servers. We have a few Windows Servers 2019, and we have onboarded those both onto Defender for Endpoint as well. Those servers are not managed by MDM because they are Server 2019, but we have onboarded them so they are being managed by Defender for Endpoint as well.

This solution definitely increases our security posture. When you are reviewing your existing fleet or endpoints and based on the configuration that you put out of your Defender for Endpoint, you then receive a security score from Microsoft. Depending on what rules you have configured, what policies you have deployed, and what attack surface reduction rules that you have set up and deployed, it is almost gamifying information security in the sense that you are always trying to achieve a higher score. The more hardening you perform on your endpoints, the better score you receive. This generally tends to give you a better peace of mind, but also makes you secure at the same time.

I like the fact that it is baked into the Microsoft platform. 

Since we have deployed it, we have been really impressed with the way that everything just stitches together really well. You can access all your security data and telemetry from a single pane of glass on the Microsoft Security admin console. You can access all your endpoints, see how your antivirus is running, and get all your vulnerability scans and reports. In the software inventories, you can review your known vulnerabilities and understand whether those are zero days or if there are active threats out in the wild. Essentially, you don't need to jump into different admin consoles. You have everything built into Windows Defender Security Center, which we find really useful.

If you consider our organization, we are a fairly Mac-heavy organization. At the moment, around 80% of our fleet are Mac OSs. We made a conscious decision to roll out Defender for Endpoint against all our endpoints, whether it is Windows or Mac OS. However, one thing that we have noticed is that there is definitely no parity on the platform between the two operating systems. When you are configuring, deploying, and onboarding machines, you can get very granular with your security configuration when you are deploying it to a Windows's endpoint. For Mac OS, it is a lot more straightforward. You don't have the ability to apply as much configuration as you would on Windows. That is definitely something that has room for improvement. 

I am also not sure how well the EDR functionality works on the Mac OS platform. It just provides an antivirus and the full EDR capability is not there on a Mac OS. 

The web filtering needs a little bit of work. We are actually in the market at the moment for a third-party web filter or cloud secure web gateway to try and plug that hole since it is a bit of a pain point for us. I don't think we will use the baked in version from Defender for Endpoint.

On the Mac OS platform, there is no parity between Windows and Mac OS. The solution is very feature-rich and very well-integrated into Windows, and I guess baked into Windows 10 and Windows 11. Whereas, on the Mac OS platform, there is still some work there to give it a more feature-reach platform.

I have been using it for about a year.

With Windows, we have been very happy. We have had no issues or problems whatsoever. We had one issue on the Mac OS platform when an update to Mac OS was deployed. It wasn't a major update, like Monterey. It was a point update. So I think it might have been 12.2.1 where the Defender icon was starting to display across, which means I found a threat or it's not working properly. We had that across a handful of machines. I did a bunch of Google searches and sort of realized this was happening to a lot of other organizations, so it was probably a false positive.

I contacted Microsoft support who confirmed that it was just a visual glitch. I guess Apple is well-known for this. When they do push out their updates, they attempt to break the occasional third-party system. That was the only issue that we have encountered, which was more a visual glitch than an actual threat.

It is pretty much zero-touch because the definitions sort of update themselves. The application updates itself because it is deployed through Microsoft Intune. Therefore, the maintenance is pretty straightforward.

It is very scalable. Because it is cloud-based, it is elastic in its nature. You can onboard machines en masse. Whether you are onboarding 15 machines or 1500 machines, it is very straightforward.

As we scale up, this is now our AV and EDR of choice. Every new machine will be rolled out or onboarded to Defender for Endpoint. We will be sticking with it in the long-term. We have also the logs and telemetry from Defender for Endpoint being ingested into our MDRC platform.

The technical support is very good. Wherever I have worked with them, we have always been enterprise customers. Whenever I have raised a ticket for support, you generally receive a phone call anywhere from 10 minutes to three hours after raising your ticket. Even if it is not a P1, but a P2 or P3 ticket or just a request for information that you have generated in the form of a ticket, they will respond back to you quickly.

They have good levels of escalation. So, if their first line support is unable to help, they can quickly escalate to the second or third line. I have never really had any problems with Microsoft support. That is across Defender for Endpoint and Microsoft Endpoint Manager as well as for the productivity throughout Office 365 and Azure Active Directory.

I would rate them as eight out of 10.

Positive

We currently have an MSP in place, which is a managed service provider, who manages all our IT support, service desk, and desktop support functions. They had already purchased an antivirus subscription for the organization when I joined the organization, and it was a fairly basic one. Our biggest problem was that it does not have any SIEM integration. 

When we decided to go down the route of having a SOC or MDR service, we couldn't ingest the logs from the antivirus platform into their SIEM. That is when the hunt started for a new AV service.

I wouldn't say the user impact has changed on top of the AV product that we had before.

The initial setup was very straightforward. Microsoft, as an organization, is quite well-incentivized to get you to use their own products. There are hoards of material out there via their social media channel, through their own documentation, or the Microsoft Learn platform. There are reams and reams of user guides for you to go through, all of which are fairly straightforward. They are regularly updated as well.

It is all cloud-delivered so there isn't any on-premise infrastructure that I need to maintain, patch, or configure. It is literally all configured in the cloud. So, it was a very easy setup process for me.

It took days to get a proof of concept together on a handful of machines. Over the next few weeks, once we got the go ahead and thought, "You know what? We are going to go with this." It was just a matter of weeks and that was more down to team availability. We needed to sit down and offboard the existing AV, which we weren't particularly happy with, then onboard Defender for Endpoint. So, we tied that project with our MDM rollout. Therefore, while we were deploying our MDM solution and enrolling the device, we were onboarding the machine to Defender for Endpoint as well.

I actually set it all up myself. I am the only technical person at the organization. I have worked with Microsoft quite extensively in the past, and I have used their fast track consultancy services in other organizations that I have worked with as well. Therefore, I am quite confident and familiar with Microsoft technologies. 

We then signed up with an MDR supplier who does managed detection and response. Essentially, that is a team of cybersecurity experts who connect to our infrastructure and all the data telemetry from our endpoints feed up to their platform. If they see any threats, anomalies, or events, they will then jump in, reviewing and remediating as required.

We had a consultancy session with one of their Microsoft consultants around a month ago, where they reviewed the setup that I configured. They put in two or three recommendations to harden the setup a little bit more, but they were overall pretty happy with it. Thus, if I can do it, then it can't be that difficult.

There is less overhead in terms of having the system administrator or information security manager jumping around different systems and trying to actively keep a handle on our security posture across the organization. Instead, everything is right in front of me.

One of the first things that I did when I came onboard in the organization was scrapping our reseller agreement. I registered us as a not-for-profit with Microsoft, and we now get subsidized licensing at effectively half price. It just sort of makes sense for us. Now, we buy our licenses directly from Microsoft rather than our formal license reseller.

Even if you are not registered as a not-for-profit, the offering that they have is definitely worth consideration. This is in the sense that the E5 stack just gives you so many benefits. You get your entire productivity suite through Microsoft 365 apps. You get all your security and identity protection. You get the Defender for Endpoint and Defender for Identity. You get the cloud access security broker as well. You get Azure Active Directory Premium P2, which gives you so many good things that you can configure and deploy. You don't have to configure them on day one, but you have access to so many different tools that will protect your data, security, endpoints, and identities that you could build out a security strategy 18 months long, and slowly work your way through it, based on what you have available to you through your license.

You can purchase some add-ons, like Microsoft Threat Expert team. I have not read too much into that, but my understanding is that comes at an additional cost. Since we have a dedicated MDR and SOC sitting on top of our Defender for Endpoint, it is not something that applies to us anyway.

We are E5 customers. Essentially, we have the flagship license. We looked at a lot of different organizations and vendors for our antivirus needs. We spoke to the usual suspects: CrowdStrike, Sophos, and Darktrace. 

Because we also have a Gartner subscription, we reached out to our Gartner analyst, and said to them, "Look, we have the E5 license and know that Microsoft doesn't have the greatest reputation when it comes to their antivirus products, but we understand they have come on a lot over the last few years. This is the direction that we proceed. We want to deploy Microsoft Defender for Endpoint. We then want to layer an external managed detection response service on top of it that will essentially provide 24/7/365 monitoring for alerts and anomalies." Gartner advised us that it has improved to the point where they are now considered one of the leaders on their magic quadrant, so we should be absolutely fine with it. 

Originally, Microsoft wasn't in mind for us at all. We sort of had our heart set on CrowdStrike because we were really impressed with them. We got quite deep into advanced discussions with them and Darktrace as well.

The deciding factor for going with Microsoft was the budget. We were already paying for the E5 licensing. So, we were allowed to use Defender without any extra costs. We could just enable and configure it. We thought that we would use the budget left over to purchase a dedicated MDR service who would maintain an overall ability for all the endpoints to connect with it. We could also expand that to our Google Cloud Platform as well as our AWS and Azure Cloud environments. We could also extend that service onto our physical appliances, e.g., the logs from our on-premise firewalls, security appliances, and routers.

We felt that in terms of scaling up to get to the security posture that we needed, this might be a better solution for us. Whereas, CrowdStrike and Darktrace, at the time, were more focused on the endpoints. For example, if there was some suspicious behavior happening on our Azure Active Directory and our CEO's user account was under a brute-force attack, then CrowdStrike wouldn't necessarily pick up on such an attack because they are more focused on the endpoint rather than the cloud instances. Thus, we thought Microsoft gave us better coverage overall as well as the fact that we were already licensed for it.

It just made sense for us to go down that direction. We just felt we would have a more well-rounded approach if we went with Defender for Endpoint supported by the MDR service, who would then provide monitoring over all our cloud instances, endpoints, and on-premise infrastructure and appliances.

One of the main benefits is cost. Being an E5 subscriber, we are essentially already paying for Defender for Endpoint. However, it wasn't on our initial list of antivirus solutions when we were going out to market. We really felt that we were going to go for a managed service, such as CrowdStrike or Darktrace. When we decided to go for Defender for Endpoint, we created a cost savings. So, it was easier for us to prove the business case to our senior management.

A good antivirus is something that sort of happily sits in the background and just pretty much does its job until it is needed. It is just sitting there constantly watching and monitoring. Then, if it does need to intervene or remediate against the threat, that is when you know, "My antivirus is happily working." We haven't had many incidents to deal with. To be honest, we have had a couple of false positives. 

Definitely shortlist them in your list when you are out looking for a new vendor. What tends to happen with a lot of IT professionals is that they overlook the Microsoft offering because of the reputation that Microsoft Defender has had in the past, when it came to its consumer version. However, they have spent the last few years completely revamping their security stack. I think it offers a really well-rounded, holistic approach to cybersecurity now. They are definitely worth considering next to CrowdStrike, Sophos, and Darktrace.

A lot of organizations are probably like, "Oh, no, we don't want to get Microsoft. We don't want to get Defender. We want to get an established name," but I think Microsoft has put a lot of effort, budget, and development time into their security stack. It is a great suite. 

As their Azure platform grows, they leverage that to power and drive their Defender for Endpoint. A lot of the protections that they deploy are cloud-delivered platforms. So, they are picking up telemetry from millions of different signals and endpoints. They have so much data and can see trends really quickly.

I would rate them as eight out of 10.

The solution is primarily used for securing endpoints, mainly desktops and laptops.

We're taking the adoption in phases. We started with endpoints and we want to expand into other capabilities at the application level.

We've mainly used it for endpoints. However, we've also used it for DLP as well. We're also in the process of implementing it for cloud and identity as well. However, it's very good for endpoints, and that's our main focus. 

The malware protection is good.

The visibility it provides is very useful. We can combine visibility with wider security features and alerts around malware, misconfiguration, or any other kinds of threats. The cloud portal is quite good. From there, we are able to see alerts and have colleagues review issues and monitor to see if any patterns arise. It's serving us quite well overall. It allows us to look at other items, like application and browser control. 

It helps us prioritize threats. We have a process in place now where we can review issues and remediate them effectively.

We have been able to integrate a variety of Microsoft security products together. We use Azure AD, for example, and we've begun to implement DLP, among other items. We're looking at labeling and tagging and will expand into that soon. 

Defender has more stringent system requirements than, for example, Check Point. So when we implemented the Check Point Endpoint agent, that solution didn't mind what version of Windows you were using. When we moved to Defender, Defender had certain system prerequisites that had to be met. So we had to make sure that we're on a minimum version of Windows when we're utilizing Office, and Office has to be a particular version as well. It has more stringent system requirements that have to be met before you can implement it.

It works natively together with other Microsoft solutions. Once you get more and more of those different components across the environment, then you start to get better visibility. So, rather than having lots of different solutions, you have fewer solutions and a single vendor solution. That way, you start getting into a position where you get better visibility and integration as well.

The standardization is good. It's important. It's helping me with monitoring and learning.

Updates and upgrades are quite smooth and seamless. 

Defender helps us automate routine tasks. Quite a lot of Microsoft is straightforward for us now. Previously, we didn't have enough resources and were unable to look at the alerts. Having this in place makes things a lot more straightforward for us. We have both the technology and the people in place now, alongside the process. We do see the benefits in that, and that's why we're continuing our adoption across the estate in terms of client and server as well. 

It's helping us avoid looking at multiple dashboards and centralized monitoring. We're not fully there yet. We're getting there.

While we haven't witnessed time saving yet, once it's fully deployed, it will. By then, we'll have standardized processes across a single solution. We have saved money, however, as we continue to reduce non-Mircosft systems. Since we won't be using various competing technologies, we can save on licensing costs. We've likely so far saved 15%.

While it's hard to estimate exactly how much, the solution has helped us decrease time to detection and time to respond. 

We'd like to see integrations with more vulnerability scanning solutions like Tenable. It would be good to be able to compare both systems to threats that are arising. 

I've used the solution for the past couple of years. I haven't used it, however, on an active basis. It's not a solution that requires active engagement. 

The solution is stable. We've had no issues. 

We've had no issues with scaling. We're scaling up to just under 2,500 systems.

We haven't had much cause for raising tickets; however, largely support is very good. We did receive initial support during deployment and have a unified support agreement. It's simple and straightforward when we do need help. 

Neutral

We have used a Check Point solution as well in the past. We're moving away from other competing technologies. We had a number of issues with Check Point in terms of the mix of client devices and operating it in a VDI environment. It wasn't as reliable as we would have liked. It might have also been a resourcing issue - not just a Check Point issue.

In terms of the actual implementation, once everything is in place, it's quite smooth, and you see the benefits quite quickly as well.

I was not directly involved in the deployment of Defender. I was more involved in procurement. 

Defender is part of the plan we signed up for. Overall, it's part of a wider suite and is representing well, although it's hard to gauge how much of our overall licensing price is based on Defender as a product. It's part of a wider investment in Microsft 365. 

We have been through a merger in the last five years, so there were multiple solutions we were using, such as Trend Micro and Kaspersky, as well as Cisco, that we considered before deciding to standardize under Microsoft. 

We are starting to also use Microsoft Defender for Cloud. We have a small POC that we are getting off the ground. We have not yet explored bidirectional sync capabilities.

I'd rate the solution nine out of ten.

I would advise new users to just be mindful of system requirements. You do need to have a relatively up-to-date Windows estate. Take into account legacy considerations in terms of displacing other non-Mircosoft solutions.

Our primary use case is for protecting Windows 10 endpoints. We use it for email scanning and application control, we can run analytics through it, and the product enables web content filtering. The Defender 365 package is all-encompassing now; it's a good product.

The solution is deployed across our whole business with 3,000 endpoints, including phones, laptops, tablets, and desktops, with 1,700 end users.

We use multiple Microsoft security products, including Defender, Defender for Cloud Apps, Identity Manager, and Intune. We have the whole security package.  

I was the infrastructure engineer who integrated the products, which was elementary; we rolled out via Intune and used SCCM to build the endpoints.  

The solutions work natively together to deliver coordinated detection and response across our environment, and it's better than using Symantec, for example. Defender is the best product out there; it's built into Windows, and it makes sense to use built-in products. This coordination is strategically important to us, as it makes passing knowledge on to the team easier because it's all in one place.   

The solution offers better management of endpoints when it comes to antivirus and malware. It allows us to separate the functionality of managing that security area rather than putting it with the infrastructure team. The infrastructure team handles the monitoring services. At the same time, virus and threat detection can go to the core security team, which takes a load off the infrastructure team and allows the security team to concentrate fully on security.

Defender for Endpoint helps automate routine tasks and the finding of high-value alerts. Once we set our rules, including attack surface reduction (ASR) rules, there's a lot of automation capability. We can apply definitions for all endpoints across our organization.  

The solution helped eliminate having to look at multiple dashboards and gave us one XDR dashboard, which positively affected our security operations. There are four staff in the department, so they appreciate this kind of management. They can see everything from one place, and our security picture is more integrated. They can even carry out basic auditing from the dashboard.  

Defender for Endpoint saves us time because we can quickly go in and search for issues raised by the security department and eliminate the threat. We have 3,000 assets, so it saves the network around half an hour and the infrastructure staff a couple of hours.   

The virus scanning capability is excellent, and it feeds all the logs into the Microsoft 365 Defender portal, making them easy to search for.

We can track web activity and see what users are logged into. The solution picks up a lot of information from machines and pushes it into the Defender 365 portal and Cloud App Security portal.

The product provides good visibility into threats. We can also log in anywhere, which is handy for the security teams.  

Defender for Endpoint helps us prioritize threats across our enterprise; we can configure specific rules concerning viruses, malware, and threat detection.   

In terms of the comprehensiveness of the threat protection provided by Microsoft security products, it's the best in the marketplace. The top three are Defender, Sophos, and Symantec; the others don't come close to these. 

The solution's threat intelligence helps us take proactive steps to prepare for potential threats before they hit because it tracks definitions and threat footprints from the cloud. These can then be identified and stopped at the front door, which is the whole idea of antivirus products these days.

The integration and effectiveness of email security could be better. It's already built-in to the solution and checks emails, scans the links they contain etc.

I've been using the solution since its first iteration came out in 2005, so about 17 years. 

The solution is scalable; we have it deployed across our entire organization to 3,000 endpoints, and 1,700 end users. 

The support is good; I don't have an issue with them. It's straightforward to go into Azure and raise a ticket, although you must know how to ask the right question.

Positive

As far as I know, my organization used Defender for Cloud Apps for a long time and Symantec for service. Symantec is configurable, but it isn't always quick enough to deal with threats, as it has different quarantining methods.

I installed Darktrace for a data center and prefer to work with MS security products.

I wasn't involved in the initial setup; I was a global admin.  

In terms of maintenance, the product is lightweight; any patches are downloaded automatically, and we can configure when they're installed in our patch definitions.

We have the E5 security license, and the solution comes with that.

I rate the solution ten out of ten.

We use Defender for Cloud and make use of its bi-directional sync capabilities, or use Intune, so all our computer objects are synced via Azure ID and pushed into Intune. This capability is there, and it functions, though there are more important features.

It isn't easy to say if the product saves us money and the business is not overly concerned about the cost of Endpoint. You get what you pay for, it's an integrated solution, and there isn't a better one on the market. It does the job, is configurable, and has limitations like all products.

Once Defender for Endpoint becomes more mature in a couple of years, it'll be the Holy Grail like Windows 7 was.

To a security collogue who says it's better to go with a best-of-breed strategy rather than a single vendor's security suite, I'd say Microsoft is the best of breed for those who want a unified approach or integrated solution. I wouldn't use other security products because it's not necessary. I'd integrate the Microsoft security suite anywhere I go.   

It is our endpoint protection solution as a part of the full Defender Suite that we use. We use it for every one of our devices, including Macs and Windows.

Each endpoint is with Intune, and then the management is done out of Azure.

It takes automated actions. If a device is found to have a virus, it will automatically remove it, isolate the device, and then notify us to follow up. That way, things are less critical when we get to them. It will stop the spread. We're a worldwide company with very few people on the security staff. It allows us to remove the risk in an immediate fashion without the staff having to jump on it, which just takes time.

It helps us prioritize threats across our enterprise. We have limited resources to deal with the threats. So, this prioritization is critical to us.

We use more than just Defender for Endpoint. We use Defender for Identity, Defender for Office 365, and Cloud App security. We use the whole 365 Defender suite. It is easy to integrate these products. The challenge is having all the features in your environment and obviously making it work within your environment because of your different applications and business processes, but all these solutions work natively together to deliver coordinated detection and response across our environment. This is critical for us because we have limited resources. So, allowing the machines to talk to each other and not having to jump from place to place just makes life a lot easier.

We use Microsoft Defender for Cloud for the hybrid cloud environment. We are not multi-cloud at this point. We use it to identify weaknesses within our environment, both prem and off-prem so that we can prioritize. We do not use Sentinel at this time.

For the most part, it gives me what I need in one spot. I do have to drill down into other dashboards for more defined reports. We go into the Intune dashboard for compliance and things like that.

Its threat intelligence helps prepare us for potential threats before they hit and take proactive steps. We use the secure score to help identify what we need to do to protect against things as they come up. It lets us know about any ransomware out there so we can jump right on those and do protections. We also use it for the compliance piece against NIST, PCI, and things of that nature.

It saves time. If I didn't have the integrated pieces of Microsoft Defender, to do the same amount and be on top of things, I would probably need two FTEs.

It has absolutely decreased our time to detect and time to respond.

The best thing I like about it is its interaction with the other Defender products. It provides the ability to push telemetry up. It gives me endpoint visibility and allows me to take automated actions. 

It is excellent in terms of visibility into threats. It is very comprehensive in terms of threat detection, and it keeps on getting better. They are consistently adding new features.

They're in the process of pulling more things together. They can continue with the integrations and provide a better way of seeing the impact of security changes, especially on the endpoint side. Before we actually flip the switch, we should be able to see the impact of security changes on the business or business applications. It would prevent breaking any business applications.

In its current rendition, I have been using it for two years.

Its stability is very good.

Its scalability is very good. It definitely scales easily.

Their support is okay. We get support through Insight, which is also our CSP. They're better. I would rate them a five out of ten.

Neutral

On the endpoint side, I've used Sophos and Symantec. We switched because of the integration between all different securities.

The deployment was relatively easy, but when you get into turning on the switches, things can get complicated because it has a lot of different features. Overall, it was easy.

We did it in-house. We had two security systems engineers doing it. 

We have seen a return on investment, but it is hard to give metrics. It has definitely allowed us to maintain a small team and increase our security posture. 

If you're on Microsoft products, and you've bought into what they're doing with Teams Voice and Office, then adding in the security piece is just a slight bump. You go with the E5 licensing, which saves you a lot of money.

With the bundling that Microsoft does, we have saved money. Buying individual point products would've cost us a lot more money than one integrated solution that also capitalizes on Teams Voice and things of that nature. Given our size, buying individual products would have easily cost us a million dollars.

We've looked at other solutions. We've looked at CrowdStrike. We've looked at Symantec. We went for Microsoft because of the full integration. The breadth of the products and the pricing were the main reasons.

I would advise following those secure scores and watching out as you start to communicate with your user base because you're going to impact applications.

To a security colleague who says that it is better to go with a best-of-breed strategy rather than a single vendor’s security suite, my response would be that you got to measure trying to do the integration because with security, to me, bringing that integration together is the key thing. You need to know how quickly you are going to be able to move from your detection to your mitigation. Are you going to turn on things on the firewalls or can you go right to the devices and isolation? The best of the breed is great, but trying to get them all to work together becomes very complex.

I would rate it an eight out of ten.

Microsoft Defender that you get by default on Windows is an unmanaged solution. It detects, but it is conventional EDR in the sense that it can detect malicious code on the machine, but it is not good from an enterprise point of view because you can't see what is being detected. The difference between Defender and Defender ATP is that you get what's called the execution chain, which is its classic use case. 

When I try to open an attachment to an email, Defender tells me that this is malicious, but when you are in an enterprise and you do receive an alert that the file is malicious, the problem usually for the analyst is that they don't know what the person clicked on. They know there was a malicious file but was it an attachment? Was it something on the USB stick? Did they download it from the internet? That's not clear. Defender ATP gives you the execution chain. In this particular example, you can see that it was outlook.exe that launched the suspicious file which then launched or tried to download various components. You can see the whole execution tree because very often, the initial thing you get is a dropper, which then downloads subsequent components, and very often, the subsequent components get missed.

It essentially gives you visibility into the execution chain. So, you are better able to do a risk assessment. For instance, if something came from Outlook, then you know that you need to go and look in exchange or look in the mail system. If the trigger came from winword.exe, then you know that it was a document, and the person had opened a document from the email. You might see Internet Explorer, when it was still there, spawn PowerShell or a command shell, which is unusual, or you might see calc.exe open a command shell. All of this detection is invaluable for identifying whether something is suspicious or not. Your EDR might not detect any of this, but ATP would see this suspicious sequence of opening and flag it. So, essentially it is the visibility and the ability to detect unusual behavior that conventional EDR would not necessarily do for you.

Its version is usually up to date. It is a cloud solution. 

Its visibility is the most useful part of it, and it also increases the effectiveness of your response. You spend less time asking the users the standard question of what did they click on. To which, they usually say that they didn't click on anything. You can go in ATP, and you can see that they opened an email and then clicked on a link, and the link is this. There is no hiding this. Users do lie.

You can detect threats that are not necessarily known because of a behavior. If you have Internet Explorer opening a command shell, that is not normal. That does not happen unless there is some kind of malicious activity. It is also very good for visibility into what PowerShell scripts do. PowerShell is a double-edged sword. It is very powerful, but in a lot of cases, there is no visibility on what it is doing. With ATP, we generally have that ability.

I like the process visibility. This ability to visualize how something was executed is valuable, and the fact that Defender ATP is also linked to the threat intelligence that they have is also valuable. So, even if you have something that doesn't have a conventional signature, the fact that you get this strange execution means that you can detect things that are normally not visible.

The other feature that I like in Defender is that because it is up in the cloud, when you're trying to do any kind of managed service, it is fairly easy to set up if you're just within one tenant, but there are a lot of things wrong with the way Microsoft does it as compared to other products like Palo Alto Cortex, SentinelOne, or CrowdStrike.

The catch with ATP is you have to have the right Microsoft license. The licensing of ATP is linked to the licensing of Office 365. You have to have an E3 or an E5 license. If you have a small office license, it is not possible for you.

Another challenge is that it is not a multi-tenant solution. Microsoft's tenant is a licensed tenant. I'm an MSSP. So, I have multiple customers. In Microsoft's world, that means that I can't just buy an E5 license and give that out to all my customers. That won't work because all of the customer data resides within a single tenant in Microsoft's world. Other products—such as SentinelOne, Palo Alto Cortex, CrowdStrike, et cetera—are multi-tenant. So, I can have it at the top of the pyramid for my analyst to look into it and see all the customers, but each customer's data is separate. If the customer wants to look at what we see, they would only see their data, whereas in the Microsoft world, if I've got multiple customers connected to the same Microsoft tenant, they would see everybody else's data, which is a privacy problem in Europe. It is not possible to share the data, and it is a breach of privacy. So, the licensing and the privacy aspect makes it problematic in some situations.

It is also very complicated. If you decide to outsource your monitoring through an MSSP, the model for allowing the MSSP to connect to your Defender cloud is very complicated. In Office 365, it is relatively simple, but because of the way it has been done in Defender—because Defender is not part of the same cloud—it is a mess. It is possible, and it is workable, but it is probably one of the most complicated integrations we do.

It is still clunky as compared to products like Cisco AMP, SentinelOne, and CrowdStrike. Microsoft took the Defender product, and they bolted on the extra features, but you can see that there are different development teams working on it. Some features are well integrated, and some features are not. They keep on improving it, and it is better than it was. It is better than an unmanaged solution, but it is far from perfect.

I have been using it for about two years. I've got a couple of customers today with it.

Its stability is lesser than some of the competition. I've seen machines having a blue screen. I've seen machines block, but it is usually a problem related to the lack of resources. I wouldn't deploy it on a machine with less than 16 gigs of memory. All the issues that we had on the laptops were essentially related to memory because it does all the analysis in memory, and it eats a lot of memory to do that. So, stability is more a function of making sure that your endpoint farm has what's available. If you've got less than 16 gigs, I would not recommend it. You need to either change your endpoints or consider using another solution because although it'll work, it can be very slow.

It is like Microsoft Office. Its scalability is good, but I don't know how manageable it would be on a big scale. The biggest deployment I've worked on was about 5,000 endpoints, and it seemed to be okay.

It is Microsoft support. It can be very good, and it can be very bad. It depends on who you get on the phone. I would rate them a five out of ten.

Neutral

It is very simple. You can deploy it through the normal tools that you use, such as SCCM. The deployment for it is linked back to your tenant. 

We use it as a headless install. It is pushed out onto all the machines. Our normal rollout process rolls out about 50 to 100 machines in no time. They can pull the agents from the internet, or they can pull the agents internally, deploy them, and turn them on. For an antivirus, it is quite quick.

In terms of maintenance, it is pretty much like other Microsoft solutions. If you are able to do the auto-update functions, that's good. The downside to it is that it is fairly heavy on network traffic. On one of the large deployments, we found we had problems with the internet gateway because the console and all the telemetry and everything else is in the cloud. It was problematic.

It runs in the background. It is like any other antivirus solution. Sometimes, it needs tuning. An example would be that we have developers who do a lot of source code compiling. They might have tens of thousands of files that get touched or accessed when they do a compile. We have to make sure that those particular file types and certain directories are not scanned on read when they're opened. Otherwise, what normally might take an hour to compile can take more than 12 hours. That's not a problem specific to Defender. It is a problem in general, but it is fairly easy to create profiles to say that for those particular groups of machines or those particular groups of users, these file directories are exceptions to the scanning.

The licensing fee is a function of your Office 365 license. The feature set you get is a function of the license as well. There is probably an E2 version, an E3 version, and an E5 version. There are several versions, and not all features are the same. So, you might want to check what features you're expecting because you might get shocked. If you only have an E3 license, the capability isn't the same.

You have to look at the total cost of ownership (TCO) because the license component is only one aspect of the block. So, if your internal IT teams know well about IBM cloud solutions, then Defender is very easy because there is nothing new. What hurts the projects is integration. It is a hidden cost because it is beyond licensing. It can be problematic if you don't have some of the other integration tools from Microsoft. So, if you don't have the package deployment platforms and all the cloud equivalents, then there is a lot of manual work involved.

The other aspect that comes into the cost is that there is an option to store. You can make the agents report a lot more information, but if you increase the storage, then you increase your Azure storage costs, which can be painfully expensive. You typically have about 7 to 30 days of basic detection data included, but if you want to keep a more detailed log so that your IT guys can go back and figure out what was going on, it would increase your storage requirements, and that can get expensive. I know customers who turned on some of the features to increase the detection rate, and they got a huge bill from Microsoft.

A weakness, as well as an advantage, of Defender is that it is always on the cloud. There is no on-prem. You deploy additional agents into the customer infrastructure, but the console and the feedback are through the cloud.

Customers often say that Microsoft has included it in their license. So, it is license-cost neutral, but just because it is included in the license and appears to be cheap, it isn't necessarily a good reason for doing it. It isn't equivalent to other EDR or XDR solutions, but to an extent, you get what you pay for. ATP is a work in progress. To me, it is not a complete product.

Customers also go for it because it gives them visibility, and it means it is one less system to manage. They have the license for it, and they just want everything in the same ecosystem. There isn't much that we can do about that. As an MSSP, we're agnostic from a technology point of view. If the customer says, "This is what we want to do," we'll take it over.

I would advise asking yourself:

• What do your endpoints consist of?
• Which operating systems, such as Windows, Linux, iOS, or Android, will you have to support? The functionality that you get depends on your license.
• What is it that you're trying to achieve by taking Defender? 
• Are there more capable XDR-type solutions out there? 

If I was comparing them, from most effective to least effective or least integrated, I would put SentinelOne, Palo Alto Cortex, Cybereason, Microsoft Defender, and Cisco AMP.

If you want to get into the advantages of XDR solutions, which is about the detection capability coupled with artificial intelligence (AI) and data leaking, then it may not be the solution that you want. If you also want to be able to do threat intelligence, it is not the solution for you. That's because essentially the threat intelligence features are not there. You can get some threat intelligence from Azure, Microsoft Sentinel, etc, but it is not in the product like with Palo Alto Cortex, SentinelOne, or Cybereason.

I'd give it a cautious six out of ten.

We use Microsoft Defender for Endpoint as an Endpoint Detection and Response (EDR) tool, as well as for vulnerability management.

I appreciate how easily Microsoft Defender for Endpoint integrates with our environment and the wide variety of logs it provides compared to other EDR tools. The policies provided are quite effective and easy to implement, which simplifies the onboarding of newcomers. We continually test new policies, making threat detection and response efficient. Automation capabilities have allowed us to create workflows that automate detecting true or false positives.

I believe that vulnerability management could be improved by making it easier to pull reports and providing more detailed information on how Microsoft Defender for Endpoint detects vulnerabilities. Our partner vendor mentioned that these updates might get more granular in the future.

I have been using Microsoft Defender for Endpoint for the past couple of years.

Initially, I experienced performance issues that hampered our servers. However, after setting appropriate exclusions, everything seemed to work fine.

Microsoft Defender for Endpoint is scalable. I did not encounter any limitations in terms of scalability.

When I had performance issues and needed clarity regarding certain legitimate applications being blocked, I raised a few tickets with Microsoft. Their responses have been adequate. Overall, I would rate them eight out of ten.

Positive

I used Symantec and Trend Micro before Microsoft Defender for Endpoint. Symantec was an on-premises solution, and we needed a cloud-based solution. After our company merged with a client, we switched from Trend Micro to match the client's tools, including their use of Microsoft Defender for Endpoint.

The initial setup was straightforward as we had ample experience in multiple migrations and deployments. We did not face any significant challenges in implementing Microsoft Defender for Endpoint in our environment.

Our implementation strategy was to install Microsoft Defender for Endpoint as a dummy software initially. With the help of our qualitative system engineering team, we deployed it on all machines, enabled monitoring mode, and compared it with current antivirus software. Eventually, we completed the deployment, disabled the previous antivirus, and made Microsoft Defender for Endpoint our primary. The process went smoothly without any outages or escalations.

Overall, I recommend Microsoft Defender for Endpoint due to its features and capabilities, which cover more loopholes than other EDR solutions. I rate the solution nine out of ten.

We use Microsoft Defender for Endpoint to protect our devices from virus and malware attacks.

Microsoft Defender for Endpoint provides visibility into threats. Using the solution we can see threats easily and address them in order to protect our devices.

The solution provides an overview and we can configure it to have a higher queue, to take action against any risks.

The prioritization of threats is very important to us. With Defender, we can prevent attacks in a number of ways. When we are alerted about a potential threat, it is important to prioritize and take action quickly. We can check the type of incident and confirm the threat level.

We also use Microsoft Sentinel. The solution enables us to investigate threats and respond holistically from one place. Our success is also a result of our four-year investment. I have invested a lot of time in studying Microsoft products and technical subjects such as firewalls.

Microsoft Defender is a good tool. As an anti-virus solution, it helps monitor for any attacks. The solution works similarly to an alarm and is very important. Microsoft Defender is the best protection solution for me, it's safe to use, and I can see the alerts in real-time.

The benefits of Microsoft Defender for Endpoint are immediately clear when implementing it across the enterprise. Within a week the entire enterprise noticed the benefits. The solution communicates with all employees through all devices across the organization. For me, Microsoft Defender for Endpoint is the best.

Microsoft Defender for Endpoint has saved us around two months a year of time.

The solution significantly reduced our detection and response time because it is integrated with all the devices across the enterprise. All the devices are constantly being analyzed and monitored so in the instance there is an anomaly detected we are notified and able to respond quickly.

Microsoft Defender for Endpoint is different from other security tools because we can configure it to use multiple types of scanning or archiving. Microsoft Defender is an important tool for our security arsenal. We can also use the solution to perform many tasks.

Integrating Microsoft Defender for Endpoint with other Microsoft solutions is easy as long as the organization has a proper implementation process. The devices and materials need to be organized and connected in a way that is efficient for the organization, and the implementation process must be considered.

Our integrated solutions work natively together with Microsoft Defender for Endpoint to deliver coordinated detection and response across our environment which is very important.

Sometimes the software doesn't work the way we expect it to, and in those cases, we can't communicate with a device because it may be infected. When this happens we can't access the device directly or implement the interface.

I have been using the solution for three years.

The solution is stable.

The solution is very scalable.

I give the solution a nine out of ten.

The comprehensiveness of Sentinel's security protection is linked to identity management and is very easy.
