Enhanced visibility and exposes vulnerabilities but needs more integration

I am currently in the pilot stage of implementing Microsoft External Attack Surface Management (EASM). My organization is transitioning to a comprehensive track of Microsoft solutions, and we will move to full-scale production in another year, maybe Microsoft External Attack Surface Management…

Integrated defenses have unified threat hunting, phishing simulations, and identity investigations

I appreciate Microsoft Defender XDR's MDE, Microsoft Defender tool, which has Attack Simulator. Instead of doing a phishing campaign and getting a separate tool, Microsoft Defender XDR does it all. These features of Microsoft Defender XDR have helped us conduct a phishing campaign quarterly, which has been beneficial. I also appreciate the fact that it has Defender for Office integrated, Defender for Identity, and everything integrated together. I would describe the process of using Microsoft Defender XDR to prioritize incidents in my security operations as quite decent. I appreciate the automatic alerting system where any incidents or alerts we receive come directly to our email. From there, we can open the email, go directly to Microsoft Defender XDR, and start our investigations and remediations. I perceive the integration of security and identity access management in Microsoft Defender XDR as affecting my identity protection strategies very well because it is well integrated with Purview, integrated well with Entra ID, and integrated well with Exchange. I especially appreciate MDO, the Office product. If anything happens and I want to conduct an investigation, it takes me directly to Exchange, where I can also investigate any emails or phishing incidents. Instead of going to different portals, everything can be done from Microsoft Defender XDR. If necessary for further investigation, Microsoft Defender XDR then directs me to that environment. I would assess the integration of AI in guiding security actions within Microsoft Defender XDR as quite positive. Recently, Security Copilot went big, and it is beneficial that I can use that, especially to write KQL. I can do threat hunting features and intelligence all within using Microsoft's Security Copilot. It also has a nice AI feature for threat hunting. I know that all the Defender logs go to Sentinel, and I can pull it up from Microsoft Defender XDR or from Sentinel. The fact that I can actually do all that within Microsoft Defender XDR is a nice feature. In the top module, I can do threat lookups, and I can actually type KQLs in Microsoft Defender XDR and look up incidents. Predictive shielding has had a nice impact on my proactive security measures. It is beneficial that it has, similar to Entra ID, a secure score. For me to improve the product, the secure score helps me out. If I rate it from highest to lowest, I can see what things I can improve. Secure score helps me see what areas I can improve in Microsoft Defender XDR to increase my score and bring it to 80 or more. Knowing Microsoft Defender XDR from using it since 2019, before COVID days, I know that they have improved significantly. It is much more user-friendly and has a very nice vulnerability feature that I find handy and useful. The fact that this feature integrates into Intune is also very decent.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"It seems to be better at protecting from cyberattacks."

"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."

"Scanning, vulnerability reporting, and the dashboard are the most valuable features."

"Microsoft Defender XDR is a complete package of different Defender solutions, including Defender for Endpoint, Defender for Office 365, Defender for Cloud, and Sentinel SIEM, among others."

"Vulnerability assessment and just-in-time access are some valuable features of Defender for server plans."

"I like that Defender is easy to use and the alerts are all in one central location."

"The best feature is probably the alert generation. When I do a security reset, the other session triggers instantly from the Defender console, and I can work on it. The policies are three times, but they are also ready to install it."

"The most valuable feature of the solution stems from the fact that Microsoft Defender XDR is easy to integrate with other Microsoft platforms or products."

"On the Windows side, Microsoft Defender XDR is definitely integrated into the operating system. Once we have it on the security dashboard, we can see a real-time storyline."

"For technical support, I would definitely give a rating of nine out of ten."

More Microsoft Defender XDR pros

Cons

"Further integration across different Microsoft products would be an improvement."

"With Microsoft, support is always crazy, it's not easy to get support."

"The integration is not as seamless compared to competitors like Palo Alto."

"There is no common area where we can manage all the policies for the EDR, third-party solutions, devices, servers, Windows, Mac, etc., but it's on the road map, and we ware waiting for that feature."

"The price could be better. It'll also help if they can continuously update and upgrade the solution. Every day there's a new virus uploaded into the network, and we have to keep updating it to identify all these things."

"What could be improved in Microsoft 365 Defender is its licensing, e.g. it should be more consolidated and would be good if it has some optimizations. Improving the alerts and notifications, in terms of adding more details, would also be good for this solution."

"Some of our older hardware experienced a slight bump in CPU and memory usage. Although I don't have empirical data to back that up, I would suggest possibly more streamlining in the software."

"When discussing the secure score, which includes overviews and recommended actions, some of these recommended actions are not applicable to us, particularly those related to Microsoft Internet Explorer, which we do not use in any of our environments."

"There is definitely scope for improvement in the automation area. Because the solution is a SaaS platform, we don't have the overall ability to automate stuff.... There is no direct way to go ahead because it's a SaaS platform."

"The abundance of sub-dashboards and sub-areas within the main dashboard can be confusing, even if it all technically makes sense."

"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."

Pricing and Cost Advice

Information not available

"Understanding the subscription model has been a bit challenging, as every feature or requirement comes with an additional cost."

"On average, we pay around 55 euros per user for the services and features we receive."

"The functionality is fantastic, but for medium and small-sized companies it's overpriced. It would be better if it were a little bit cheaper."

"The solution is too expensive."

"The licensing fee for Microsoft 365 Defender is fair."

"It is 15 dollars per server per month. It is worth it, but it can be costly. It depends on the company's size."

"Sometimes 365 Defender is expensive, but it can be moderate, depending on the organization's size and the license type. We're satisfied with the cost because it gives us a product that protects our entire environment with DLP. To compromise some cost, of course, we are to complete the most secure environment."

"Defender XDR is included in the E5 license, but it's a bit too expensive."
