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

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

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

"We can automate routine tasks and write scripts to carry out difficult tasks, which makes things easier for us."

"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."

"The most valuable aspect is undoubtedly the exploration capability"

"The comprehensiveness of Microsoft's threat detection is good."

"As a reseller and partner, the advantages of Microsoft Defender XDR are numerous; I have stopped many threats for many organizations using Defender alone, and I have saved significant IT management time by avoiding manual updates and manual work."

"The visibility into threats is also very impressive because Microsoft helps you predict things and provides analytics to help you really improve your security. And all of this technology works across the domain, so it is pretty helpful in terms of threat analytics."

"The portal is quite user-friendly. There is integration with Office, Intune, and other products from the same portal. From there, we can see which policies are installed on a particular machine. We also can manage devices, groups, and tagging."

"Defender is easy to use. It has a nice console, and everything is all in one place."

More Microsoft Defender XDR pros

Cons

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

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

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

"Since all of our databases are updated and located in the cloud, I would like additional support for this."

"Because of the training model, Defender XDR's automatic response sometimes blocks legitimate users and activities. Also, the UI sometimes responds slowly."

"Microsoft Defender XDR is not a full-fledged EDR or XDR."

"The solution could enhance the threat Intelligence feature by making it more relevant to specific industries. Much of the threat intelligence information isn't directly applicable to our environment. It would be beneficial if the threat intelligence were tailored to the industry, such as healthcare or fintech, where the solution is being used."

"Troubleshooting in Microsoft 365 Defender can be inefficient."

"It would be beneficial to have a more seamless experience with everything consolidated in one place, particularly when dealing with aspects related to the Exchange console."

"Support is hit or miss. Microsoft wants you to buy premium support contracts. Though they call themselves professional support, it's almost like throwing questions into a black hole. You get an answer, but it's never helpful."

"This solution could be improved if it included features such as those offered by Malwarebytes."

Pricing and Cost Advice

Information not available

"The product is fairly priced for what we get from it."

"Microsoft Defender falls within a mid-tier price range compared to other security solutions."

"There are no issues with pricing, but sometimes, the clarity in licensing is a concern."

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

"365 Defender is billed per account. I don't know the exact price, but my supervisor told me that Microsoft Defender is cheaper than the alternatives. It's bundled, so you get all the features in one place."

"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."

"They have moved from a licensing model to pay-per-use... The question is: What happens if, for any reason, there's not enough budget to accept this model? That could be a great problem."

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