    • "Another noteworthy feature that I find appealing in Microsoft Defender is the credit-backed simulation. This feature enables organizations to train their users on effectively responding to phishing emails through a simulated training environment."
    • "In the future, it would be beneficial for Microsoft to consider making the product more user-friendly or simplified for those who are interested in using it. Currently, it requires a high level of technical expertise, making it challenging for beginners or less experienced individuals."

    What is our primary use case?

    Microsoft 365 Defender works together with Exchange Online is my area of specialty.

    Microsoft 365 Defender incorporates a capability to identify potentially malicious emails or emails originating from suspicious senders.

    How has it helped my organization?

    Previously, we encountered a significant number of spam emails and suspicious emails, and users were inadvertently interacting with them. However, we have made progress in addressing this issue. We have conducted attack awareness training to educate users on identifying suspicious emails, and Microsoft Defender has played an important role in preventing such emails from reaching our inboxes. As a result, we have noticed a reduction in the volume of spam emails and an increase in the delivery of trustworthy emails. Considering these improvements, I can confidently state that we are in a better position now in terms of email security compared to the past before the implementation of Microsoft 365 Defender.

    Within Microsoft 365 Defender, specifically using Advanced Threat Protection, you have the ability to define rules and actions for high-value alerts. 

    By using Advanced Threat Protection, you have the capability to conduct thorough investigations and delve deeper into the search for specific threats that you suspect may be present within your organization. 

    Within the Microsoft 365 Defender suite, you have access to numerous features that enable you to effectively track and investigate potential threats within your organization.

    Automation significantly impacts our security operations in a highly beneficial way. It revolutionizes our approach by providing a centralized IT vendor admin center where we can execute all our search queries and obtain the desired information from a single interface. This unified platform streamlines the entire process by consolidating various components and their respective search processes into one, eliminating the need to navigate through multiple individual interfaces. With Microsoft 365 Defender, we have the convenience of accessing and investigating different areas of interest from a single standpoint. This not only saves us substantial time but also reduces effort and enhances overall efficiency in our security operations.

    The consolidation of security operations has had a significant impact on our effectiveness and efficiency. It has resulted in improved response times, enabling us to swiftly pinpoint the potential sources of threats. We have observed a reduction in incident response time, allowing us to address security incidents more promptly. Additionally, the consolidation has enhanced the efficiency of our deployment processes, streamlining our overall security operations. These notable impacts have greatly contributed to our organization's ability to proactively identify and mitigate threats, ultimately bolstering our security posture.

    Threat intelligence is an essential component in proactively preparing for potential threats and implementing proactive measures. While I have not personally engaged with this particular feature, it is widely acknowledged that staying informed about current threat intelligence is essential.

    Although preventive measures are in place to minimize maintenance issues, there can be instances where threats successfully circumvent those safeguards. However, the capability to detect and identify threats before they cause harm to the system remains a valuable advantage. Anticipating the effects of this specific feature in Microsoft Defender is something I am eager to experience, as it appears to be a fascinating addition to the security measures.

    What is most valuable?

    Another noteworthy feature that I find appealing in Microsoft Defender is the credit-backed simulation. This feature enables organizations to train their users on effectively responding to phishing emails through a simulated training environment. 

    Indeed, the credit-backed simulation feature in Microsoft Defender operates by sending simulated phishing emails to users within the organization based on the configured settings. When a user interacts with the email by clicking on a link or taking any action, they receive a notification informing them that it was a simulated phishing attempt. This simulation serves as a valuable training tool, helping users learn how to detect and respond to phishing emails effectively. By experiencing these simulations, users can enhance their awareness and develop the skills necessary to prevent falling victim to real phishing scenarios in the future. This feature is highly valuable in improving the overall security awareness and resilience of the organization's users.

    In terms of visibility, Microsoft 365 Defender offers a comprehensive and detailed overview of threats and potential traces identified within your organization. 

    Within Microsoft 365 Defender, you have the ability to configure specific criteria and assign high-risk values to certain indicators. This allows you to align with compliance regulations and establish your organization's threat determination framework. By leveraging Microsoft 365 Defender, you can implement and enforce these criteria to analyze and assess potential threats in your environment. 

    I believe that Microsoft has the potential to greatly enhance the efficiency of the application by incorporating advanced capabilities into this feature. By providing users with the ability to customize and tailor threat detection according to their specific needs, Microsoft could significantly improve the overall effectiveness of the application. The addition of advanced capabilities would be a valuable enhancement, complementing the existing features and further strengthening the overall functionality of Microsoft 365 Defender. This would undoubtedly be a welcome and highly beneficial addition to the platform.

    Microsoft 365 Defender demonstrates a commendable level of comprehensiveness in its threat protection capabilities. However, it is important to acknowledge that false positives and false negatives can be potential challenges in any security solution.

    I primarily focus on using two key features within Microsoft Defender: the attack training simulation and the threat policies integrated with Azure Guard Protection.

    The dashboard is one of the features of this application.

    Implementing this solution has proven to be time-saving as it enables us to effectively track down suspicious and malicious attachments that may accompany emails. Even if users tend to click on attachments without much thought, we have successfully prevented and significantly reduced security breaches that were prevalent in our past security architecture. The ability to identify and mitigate potential threats has greatly improved our overall security posture, providing us with enhanced protection against breaches and unauthorized access to our systems. By leveraging this solution, we have experienced tangible benefits in terms of minimizing security incidents and safeguarding our organization's sensitive data and resources.

    There was a specific incident where an email was received containing an executable file, and unfortunately, like many other users, this particular user was unaware of the potential risks and clicked on it without hesitation. Consequently, the consequences of this action became evident. 

    Microsoft 365 Defender has provided us with the capability to pinpoint the specific machine where the application is currently present, as well as track the actions and steps that the application has already taken on that machine. This is just one example of the numerous areas where Microsoft 365 Defender has proven invaluable in our security operations. 

    While providing an exact numerical comparison may be challenging, I can confidently say that the improvement in our response capabilities with Microsoft 365 Defender compared to our previous security architecture is indeed significant.

    What needs improvement?

    It is fair to acknowledge that Microsoft 365 Defender, like any software product, is not without its imperfections. There are instances where it may incorrectly flag legitimate emails from trusted senders as spam or exhibit inadequate performance in accurately classifying certain emails.

    Aside from that, it's a pretty good solution, and that is for the emails.

    However, the main point I want to convey is that for someone who is new to it, using Microsoft 365 Defender will demand a significant amount of effort and a willingness to learn about the product in order to maximize its benefits. It deals with technical aspects and encompasses a broad range of features beyond just the mentioned warranty, such as online exchanges. To effectively utilize Microsoft 365 Defender, it is important to have a thorough understanding of its functionalities.

    It may be too complex for beginners to grasp.

    In the future, it would be beneficial for Microsoft to consider making the product more user-friendly or simplified for those who are interested in using it. Currently, it requires a high level of technical expertise, making it challenging for beginners or less experienced individuals. 

    Breaking it down into smaller components or enhancing its comprehensibility for end users would serve as a valuable advantage. In fact, it would not only impress others but also motivate them to understand the significance of utilizing I Defender in their specific situations.

    At the moment, I have limited knowledge about TripAdvisor and its offerings, so I'm unable to provide comprehensive information. However, based on my current understanding, I believe it would greatly benefit from being more user-friendly and simplifying its features. This would enable users to easily navigate the platform and maximize their experience with it.

    For how long have I used the solution?

    I have been working with Microsoft 365 Defender for a year.

    What do I think about the stability of the solution?

    To the best of my knowledge, I have never encountered a situation where Microsoft 365 Defender experienced significant crashes or unresponsiveness, aside from occasional instances of false positives and false negatives. I have found the platform to be reliable and self-service oriented, with prompt responses from the provider whenever assistance was needed.

    What do I think about the scalability of the solution?

    We currently have around a hundred users with Office 365 licenses; however, not everyone has the same plan that includes Microsoft 365 Defender. I was hoping to access the admin dashboard to have a closer look at the settings and configurations, but it seems that access is limited to approximately fifty users.

    This is managed by Microsoft you don't have to do anything.  All you have to do is understand how to use it to make it work for you.

    Similar to other cloud applications, I believe Microsoft 365 Defender demonstrates excellent scalability by seamlessly accommodating an increasing number of users. It effortlessly scales across these users, eliminating the need for extensive efforts to extend security measures to them. The scalability of Microsoft 365 Defender is highly commendable.

    How are customer service and support?

    In situations where an email that appears to have properties indicative of spam gets delivered instead of being flagged, it is advisable to contact the technical support team directly. 

    Engaging with customer support allows you to understand why such potentially harmful content was allowed into your organization. While Microsoft 365 Defender is an advanced solution, there is always room for improvement, and feedback can help drive future enhancements to make it more effective.

    By reaching out to customer support, you can address specific concerns and gain insights into how to optimize the system's performance for better security outcomes in the future.

    I would rate the technical support an eight out of ten.

    Which solution did I use previously and why did I switch?

    I use Exchange Online Protection in conjunction with exchange mailboxes.

    They collaborate closely. Collaborating with one is nearly identical to collaborating with the other due to the overlapping features between Microsoft 365 Defender and Exchange Online. Essentially, I consider them to be synonymous since their primary objective is ensuring security.

    They lack native integration and instead exhibit interdependence. I believe their collaboration is essential in order to fully utilize their capabilities and optimize the user experience. It is crucial for them to function together in order to achieve maximum benefits and enhance overall performance.

    The main differentiating factor is the expanded scope of Microsoft 365 Defender, which is evident as the primary distinction. Our utilization includes Microsoft 365 for cloud applications and Microsoft 365 for Office Microsoft 365 applications. However, when it comes to Exchange Online Protection, its functionality is exclusively focused on email boxes.

    Microsoft 365 Defender provides a broader and more extensive coverage compared to Exchange Online Protection, offering a wider reach in terms of wireless accessibility.

    In the past, we used Mimecast for email filtering, and before that, we employed Trendmicro as our spam filtering and email filtering solutions.

    How was the initial setup?

    I was not involved in the deployment process.

    What was our ROI?

    Previously, organizations had to invest in separate third-party filtering solutions to effectively address potential threats and breaches. However, the situation has now improved significantly as Microsoft 365 Defender consolidates all these necessary security measures into the comprehensive Microsoft 365 license. This consolidation brings numerous benefits, making it a win-win scenario for organizations. They no longer need to make additional purchases or manage multiple security solutions, as everything is conveniently available with the Microsoft 365 license.

    With an eligible and dependable license like Microsoft 365, there is no need to concern yourself with the purchase of an additional third-party solution, which often comes at a higher cost. 

    All these functionalities have been consolidated into a single license, eliminating the need to incur additional costs for third-party solutions such as Google Security for email features and similar functionalities.

    The time it takes for us to respond has been significantly reduced. Additionally, the time it takes to detect potential threats has also seen significant improvements.

    In situations where Microsoft 365 Defender did not successfully mitigate a potential threat or error, it highlights the need to initiate a new process to address the specific scenario. However, with the current setup, we are now able to detect and prevent such incidents in a timely manner. This proactive approach has saved us from potential future issues and the associated costs that may have arisen. Without Microsoft 365 Defender, it would have been challenging to identify and contain these threats, which could have caused widespread problems throughout the environment. The implementation of Microsoft 365 has effectively stopped such incidents from occurring, mitigating the need for extensive investments to resolve the issues. This positive outcome demonstrates a favorable return on investment, provided we fully understand and leverage the capabilities of the product to its maximum potential.

    What's my experience with pricing, setup cost, and licensing?

    I believe the pricing is fair and acceptable. I consider it to be reasonable and satisfactory.

    If you prioritize security, considering the cost should not be a determining factor. If you truly understand the level of protection offered, you wouldn't be concerned about the price. Instead, you would focus on the value provided. From our perspective, the pricing is reasonable considering the significant benefits and value we currently receive.

    Which other solutions did I evaluate?

    We recently transitioned away from those solutions and successfully migrated everyone to Microsoft 365 Defender. Since then, we have been exclusively using Microsoft 365 Defender without any changes up to the present time.

    We have no motivation or desire to switch to or explore other products, as we are already satisfied with the quality and value we receive from our current investment.

    What other advice do I have?

    Optimally managing a combination of various security solutions can be time-consuming and overwhelming. Instead, having a single dashboard where you can consolidate and run all your queries proves to be more efficient. While the intention might be to extract the maximum benefits from multiple solutions, dividing your attention among them hinders the ability to fully leverage each one. Therefore, it is advisable to identify a comprehensive solution that meets your requirements and focus on understanding how to maximize its potential and utilization.

    Furthermore, using multiple solutions in an environment can lead to compatibility issues and conflicts. When you have multiple applications performing similar functions, it can complicate matters and potentially cause problems in the future. To avoid such complications and maintain a streamlined setup, it is advisable to stick with a single solution and focus on understanding and optimizing its usage. By doing so, you can ensure better control and avoid potential disruptions that may arise from using multiple conflicting applications.

    To truly grasp the value of a service like Defender, it may be challenging for someone who hasn't experienced the need for its intervention firsthand. It is essential to engage individuals who have encountered scenarios where Defender played an important role in saving the day. When evaluating the effectiveness of the solution, it is important to involve those with hands-on experience, who have witnessed the capabilities of the product and understand how to maximize its utilization. The hands-on experience becomes paramount when screening and assessing the proficiency of individuals in dealing with this specific solution.

    I would give Microsoft 365 Defender a rating of nine out of ten. The only reason I'm not giving it a perfect score of ten is that it can be quite technical for someone who is just starting out. Additionally, there may be occasional false positives and negatives, which is not unique to Defender but is a common occurrence in various software and security applications. However, apart from these minor aspects, I consider Microsoft 365 Defender to be an excellent solution overall.

    You can scan the systems remotely to get a complete inventory of assets
    Pros and Cons
    • "Defender XDR enables you to scan a system remotely and get a complete inventory of its assets. You can gather more information from the asset inventory and apply threat intelligence using Office 365 or something."
    • "The initial time spent setting up and configuring Defender XDR is a bit longer than the other solutions. If everything were on one portal, the platforms for managing policies or alerts would be simpler. We must automate and manage policies on Intune rather than the same portal."

    What is our primary use case?

    We use the entire 365 security package. Defender XDR is primarily used for real-time malware scanning. Our company has about 1,500 endpoints. 

    How has it helped my organization?

    Before Defender, we used a different tool but were unhappy with its performance and frustrated with the deployment. Defender offers real-time scanning and alert notifications.

    By adopting the Microsoft stack, we have eliminated other security solutions. Defender XDR reduces manual work. Our organization manages more than 1,500 systems, and manual intervention on all these systems would be a huge workload. Cloud solutions are easier to manage and monitor. 

    We are a massive Microsoft shop. We see significant savings by getting all of our security from one vendor. There is a considerable drop compared to buying from other vendors. 

    What is most valuable?

    Defender XDR enables you to scan a system remotely and get a complete inventory of its assets. You can gather more information from the asset inventory and apply threat intelligence using Office 365 or something. It's a user-friendly, cost-effective, and feature-rich solution. The XDR features offer considerable value because you get more insights from your user systems.

    Microsoft Defender XDR stops the movement of advanced attacks by working with the complete 365 package. For example, you can create rules for email filtering to block phishing emails. I can create rules for email filtering. If there are any suspicious links in an email or its attachments, we can quarantine that email. It notifies the admin or the user.  The user can ask the admin to remove the email from the quarantine. We can investigate the email before it reaches the endpoint. Defender also has web content filtering and all the other EDR file features.

    Defender's ability to adapt to evolving threats is critical today. The number of attacks today is multiplying, and Defender's adaptability and awareness are amazing.

    What needs improvement?

    The initial time spent setting up and configuring Defender XDR is a bit longer than the other solutions. If everything were on one portal, the platforms for managing policies or alerts would be simpler. We must automate and manage policies on Intune rather than the same portal.

    For how long have I used the solution?

    I have used Microsoft Defender XDR for nearly 14 months.

    What do I think about the stability of the solution?

    I am very satisfied with Defender's stability. It's a reliable solution that improves our confidence in our security.

    How are customer service and support?

    I rate Microsoft support seven out of 10. I would like Microsoft's support to be a little more robust and technical.

    How would you rate customer service and support?

    Neutral

    How was the initial setup?

    Deploying Defender XDR is pretty straightforward. We deployed it in phases with deadlines. It took a couple of months. We met all our deadlines, and it wasn't a very complex solution to implement. 

    We prepared and configured the tenant. Next, we created XDR policies and groups and orchestrated our requirements. We tried pushing the policies to see if the endpoints received them and sent the required information back to the admin portal. There was a testing period before we went live. Deployment only required two people. 

    Defender doesn't require much maintenance after deployment because it's a cloud-based solution. We only need to tweak and update the policies, then push them out. 

    What's my experience with pricing, setup cost, and licensing?

    Defender XDR is reasonably priced based on the licenses we need and the solution's capabilities. At the same time, Defender is a little pricier than some of the other solutions. 

    Which other solutions did I evaluate?

    We also considered CrowdStrike and Trend Micro. Trend Micro came the closest to meeting our expectations. Ultimately, we decided to use Defender XDR because we already used most of the Microsoft products, so it was a little more cost-effective. 

    What other advice do I have?

    I rate Microsoft Defender XDR nine out of 10. Before deploying Defender XDR, potential users should be informed about the pricing, support, and the labor required to manage, maintain, and deploy the solutions.

    The system of analysis and investigation is super convenient for our customers
    Pros and Cons
    • "Microsoft XDR's system of analysis and investigation is super convenient for our customers. It integrates with other Microsoft solutions like Defender for 365 to protect email traffic from malicious external web links and phishing."
    • "Customers say they want absolutely seamless integration between other Microsoft solutions and Defender XDR, including the ability to change device settings within the Defender portal. They need to contact the IT team responsible for the device management tools to change some settings. They would prefer that those changes be initiated directly from the Defender portal or applied from Intune without involving the IT operations team."

    What is our primary use case?

    I am a consultant responsible for deploying and providing customer support for Microsoft products. We use Defender XDR for endpoint protection. It helps them secure endpoints with an advanced XDR solution that conducts behavior analysis and things like that.

    How has it helped my organization?

    Defender XDR provides more visibility into all the connected services, including the security stack and all the productivity software. They're all integrated. It's much less maintenance and has fewer headaches during integration and setup. Implementing the solution and getting the customer fully protected takes very little time. According to Gartner, it's one of the best solutions on the market,  and it requires a limited amount of time and resources to get it fully operational.

    By adopting Defender XDR, our customers have discontinued other security products. The solution can replace products like Kaspersky, McAfee, Trend Micro, and even CrowdStrike. 

    It has affected customers' security operations by simplifying permissions and reducing the total cost ownership if we discontinue all the security products that the customers used before. Customers usually save around 20 percent, but it's more than simply replacing one component with another. It replaces several security solutions like email and cloud application protection. If you compare the total cost of ownership of on-prem solutions versus Microsoft, it is better to go with Microsoft. You also get lifetime upgrades for the systems and features that you implement.

    What is most valuable?

    Microsoft XDR's system of analysis and investigation is super convenient for our customers. It integrates with other Microsoft solutions like Defender for 365 to protect email traffic from malicious external web links and phishing. Customers like that the platform provides a single pane of glass for all the security services. Many of them do not have the capacity to support complex systems, so it's better for them to have most of the tools integrated into one platform. 

    You can integrate XDR with Microsoft's identity solution Entra ID if you have a premium license. Those tools are fully integrated, but you need to purchase a separate solution called Defender for Identity to get tools to protect identities and connect the Enterprise Data Center with Defender.

    Defender XDR's coverage isn't limited to Microsoft products. You can use almost any solution and achieve the same single point of control. For example, you can integrate Microsoft Defender for Cloud Applications, which covers all the cloud service providers. It isn't limited to only Microsoft infrastructure.

    What needs improvement?

    Customers say they want absolutely seamless integration between other Microsoft solutions and Defender XDR, including the ability to change device settings within the Defender portal. They need to contact the IT team responsible for the device management tools to change some settings. They would prefer that those changes be initiated directly from the Defender portal or applied from Intune without involving the IT operations team.

    For how long have I used the solution?

    I have used Microsoft Defender XDR for five years. 

    What do I think about the stability of the solution?

    Defender XDR is almost 100 percent stable.

    What do I think about the scalability of the solution?

    Defender XDR is infinitely scalable. 

    How are customer service and support?

    I rate Microsoft standard support six out of 10 and premium support eight out of 10. The response times for basic Microsoft support leave much to be desired. It can take up to two weeks to resolve issues if you don't have a support contract. 

    How would you rate customer service and support?

    Neutral

    How was the initial setup?

    Deploying Defender XDR is relatively straightforward, but it depends on whether the customer has already integrated its on-premise infrastructure with the Microsoft cloud.

    Deployment requires one or two engineers on our side. We determine the scope of the work and the deployment before rolling out the clients to the endpoints. The biggest question is whether the customer already has the network infrastructure prepared for that service based on the Microsoft documentation. For example, we must determine if the endpoints connect directly to the Microsoft cloud or through a proxy server, firewalls, etc.

    Defender includes four or five products different products. The most useful is Defender for Endpoint, which typically takes up to two weeks to deploy, while Defender for Office and Defender for Identity take one week to deploy. Defender for Cloud Applications can be deployed in a few days. It also depends on how the customer will use it. If it's being used for compliance, the customer's requirements may be totally different. 

    The number of maintenance and administrative personnel depends on the organization's size and the number of solutions deployed. It's hard to calculate how people would be necessary for that particular part of the security ecosystem. However, Defender XDR takes up to three people to manage. 

    What's my experience with pricing, setup cost, and licensing?

    Defender XDR is expensive, but the cost is justified. Defender is included in an E3 or E5 license. If you don't have a premium Microsoft license and you purchase Defender separately, the whole model will be different. You can also pay extra for premium support. 

    What other advice do I have?

    I rate Microsoft Defender XDR nine out of 10. I recommend starting it as soon as possible, but you must also plan for any future on-premise solutions that you might bring into the system. Consider any prerequisites you need if you decide to go with the product. The biggest issue is that your network infrastructure needs to be set up according to the Microsoft documentation.

    Comprehensive security across endpoints and seamless integration within the Microsoft security ecosystem, offering a unified and proactive defense against evolving cyber threats
    Pros and Cons
    • "A crucial aspect for our team is the inclusion of identity and access management tools from the vendor."
    • "The capability to not only thwart attacks but also to adapt to evolving threats is crucial."

    What is our primary use case?

    It addresses various use cases, including monitoring and securing file storage like OneDrive and SharePoint. It has recently incorporated Teams integration to safeguard against malware. Additionally, it serves as a replacement for on-premises Advanced Threat Protection, offering enhanced capabilities. It has proven valuable in highlighting critical scenarios related to credential use and legacy Active Directory, providing substantial assistance in these areas.

    How has it helped my organization?

    When transitioning to Microsoft Defender for Endpoint from our previous use of ATP, we observed significant improvements. Legacy ATP involved numerous signals and a substantial learning curve, but Microsoft Defender for Endpoint establishes a more effective baseline. In comparison to Cylance, which generated a considerable amount of background noise, Microsoft Defender for Endpoint enables us to concentrate on the more critical alerts that demand our attention. Our team is actively phasing out disparate security tools in favor of a streamlined approach. The efficiency gained from having a single pane of glass is a powerful asset for our team.

    What is most valuable?

    One of the most valuable aspects is the comprehensive insights it provides into on-premises identities, particularly within Legacy Active Directory. This allows for the examination of use cases related to identities, ensuring there is no misuse of accounts or computers. A crucial aspect for our team is the inclusion of identity and access management tools from the vendor. Despite being a sizable global company, our team is relatively small, considering our global reach. Therefore, minimizing overhead is a top priority for us, and integrating these tools from the vendor becomes crucial in achieving that goal.

    What needs improvement?

    My suggestion would be for Microsoft to continue aligning all components within this ecosystem. This consolidation is beneficial as we strive for a more unified and comprehensive view, essentially a single pane of glass, which is highly valued. In the future, I hope for increased third-party integration. While Microsoft plays a role, it's equally important for third-party providers to step up. In our organization, the information security team has endorsed a specific set of products. Integrating the telemetry from these approved products into our systems would be immensely beneficial, providing a more comprehensive view and enhancing our overall security posture. Extending security coverage is of paramount importance. Integrating telemetry could bridge these gaps, fostering greater cooperation among individual teams within the organization. Having teams collectively examine the same information might contribute to advancing collaboration and overall security efforts. The capability to not only thwart attacks but also to adapt to evolving threats is crucial.

    For how long have I used the solution?

    I have been using it for the last three years.

    What do I think about the stability of the solution?

    It is exceptionally stable, without encountering any notable issues or complaints. Microsoft seems proactive in communication through the message center, keeping users informed about any ongoing issues, and we appreciate the clarity provided through multiple channels.

    What do I think about the scalability of the solution?

    It has the capability to scale seamlessly, especially with Microsoft's expertise in the cloud. We have over six thousand end users globally distributed across various facilities, with some on-premises deployments due to specific requirements. However, our overarching strategy is cloud-first, and the majority of our infrastructure operates in Azure. In terms of endpoints, the number is substantial, likely exceeding seven thousand when considering both servers and clients.

    How are customer service and support?

    We haven't had the need to contact them so far. In general, our experience with Microsoft support has been variable—it can be both beneficial and challenging. While they offer a wealth of resources, there are instances where the response may not align with our expectations. I would rate it eight out of ten.

    How would you rate customer service and support?

    Positive

    Which solution did I use previously and why did I switch?

    I made the switch from Bitdefender to Defender primarily due to cost considerations. In my professional assessment, Bitdefender appears adequate from a client perspective, but when it comes to enterprise deployment, I don't view it as fully enterprise-ready. We encountered numerous challenges, particularly with installing Bitdefender's agent on Server 2022, which proved to be a significant hurdle for my team, consuming valuable time and resources. The advantage of Defender lies in its ability to seamlessly bring together threat telemetry from servers across various cloud providers, including Azure, and extend this protection to our Windows endpoints, offering a robust and integrated security solution.

    How was the initial setup?

    The initial setup was straightforward.

    What about the implementation team?

    Our implementation strategy was relatively gradual and soft. We enabled the features, allowed it to ingest the data, and then began assessing the generated alerts. Taking a somewhat silent approach, we deferred more to the expertise of our information security team, considering their role as the cornerstone in this aspect. As we moved forward, we aimed to identify areas for improvement and address the specific queries and needs that our team raised during the process. Our ongoing maintenance primarily involves fine-tuning our alerts to align with our specific use cases.

    What was our ROI?

    In terms of return on investment, the potential for cost reduction is a key consideration and Defender does provide it. The time saved is substantial, especially if we can navigate through our internal processes efficiently. Specifically for my infrastructure team, using Defender for Endpoint has significantly reduced the time spent delving into emerging issues. As a rough estimate, I would say it saves us approximately six hours a week that would otherwise be spent navigating through the complexities of individual components within Microsoft 365.

    What's my experience with pricing, setup cost, and licensing?

    I find the pricing to be quite competitive, especially considering its inclusion in our E5 subscription, which provides a comprehensive set of functionalities. Initially, when I evaluated the pricing for add-ons with our E3 subscription, it seemed reasonable. However, we opted for the E5 subscription, absorbing the additional features seamlessly.

    What other advice do I have?

    I'd recommend exploring Microsoft's Learn documentation, a resource that is sometimes overlooked but provides valuable insights into the capabilities of Defender. It's a good starting point to understand its features. For large enterprises with tools like Visual Studio subscriptions (formerly MSDN), Microsoft offers the option to set up an E5 tenant for testing. This can be deployed freely for up to twenty-five licenses, excluding the Windows license. I suggest diving into hands-on experimentation in a lab environment, combining practical experience with informational reading for a comprehensive understanding. Overall, I would rate it nine out of ten.

    Top 5
    Helps us reduce the security solutions used, provides unified identity and access management, and saves our security team time
    Pros and Cons
    • "The most valuable features are spam filtering, attachment filtering, and antivirus protection."
    • "Microsoft Defender XDR is not a full-fledged EDR or XDR."

    What is our primary use case?

    We use Microsoft Defender XDR to protect our endpoints, computers, mobile devices, and emails.

    How has it helped my organization?

    In part, Microsoft Defender XDR provides unified identity and access management.

    Microsoft Defender XDR can protect 98 percent of devices.

    With Microsoft Defender XDR we can now manage all of our non-critical computers from one console. The management level and implementation level are easy. Microsoft Defender XDR is also cost-effective.

    We have been using Microsoft solutions for over 25 years so it didn't take much convincing to start using Microsoft Defender XDR.

    Microsoft Defender XDR has enabled us to discontinue the use of Kaspersky in our safe computers.

    Being able to reduce the number of solutions used has been helpful to our security team's operations. The discontinued use of other security products has reduced manual correlation. Using Microsoft has a lot of advantages, especially in management. The reduction in manual correlation is important for our organization.

    Microsoft Defender XDR saves our security team around three hours a day.

    What is most valuable?

    The most valuable features are spam filtering, attachment filtering, and antivirus protection.

    What needs improvement?

    Microsoft Defender XDR is not a full-fledged EDR or XDR. Any true XDR should be more powerful than what Microsoft is currently providing. For some public-facing companies, computers, and endpoint computers, we need additional security from CrowdStrike or other third-party XDR.

    Microsoft Defender XDR does not stop 100 percent of the lateral movement or advanced attacks. Our machines use both Microsoft Defender XDR and Crowdstrike and we have had instances where attacks were missed by Microsoft Defender XDR but caught by Crowdstrike.

    For how long have I used the solution?

    I have been using Microsoft Defender XDR for four years.

    What do I think about the stability of the solution?

    Microsoft Defender XDR is stable.

    What do I think about the scalability of the solution?

    Microsoft Defender XDR is scalable.

    Which solution did I use previously and why did I switch?

    We previously used Kaspersky, Norton, and CrowdStrike. We switched to Microsoft Defender XDR because of its streamlined management capabilities.

    How was the initial setup?

    The initial deployment was straightforward. We pushed Microsoft Defender XDR remotely across our system consisting of 300 computers. We are a team of seven people and each of us was involved in the deployment process.

    What about the implementation team?

    The implementation was done in-house.

    What's my experience with pricing, setup cost, and licensing?

    Microsoft Defender XDR is expensive.

    Which other solutions did I evaluate?

    We did not evaluate other security solutions because I have extensive knowledge of most products, their strengths and weaknesses, and their overall capabilities. Additionally, considering all our products are on Microsoft 365, a cloud-based platform, and we already utilize its various components like mail, documents, and more, integrating Microsoft Defender for threat detection and management was a natural choice due to existing ecosystem compatibility and streamlined administration.

    What other advice do I have?

    I would rate Microsoft Defender XDR an eight out of ten.

    Microsoft Defender XDR is deployed across multiple locations and departments.

    Minimal maintenance is required for patching.

    Which deployment model are you using for this solution?
