In-depth traffic analysis and proactive support reduce investigation time
The live IOC feed identifies the type, technique, and tactics used. This becomes handy since then I know what to refer to from the playbook. For instance, if I take a use case of someone with Mimikatz installed on their system, knowing the nature beforehand reduces investigation time. I can quickly apply the playbook to resolve incidents in less time.

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…

Quotes from Members

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

Pros

"The live IOC feed identifies the type, technique, and tactics used."
"The feature I have found most valuable is directory monitoring. We experienced an instance of threat actors trying to ensure a complex and massive attack against our customer's infrastructure on the forum. That is, they were animating people on a formum. The solution alerted us to this two days ahead of the attack, which gave us plenty of time to prepare for it."
"Mandiant Advantage is excellent at providing the full context and all the information, where the information was found, and the full data, including the raw data that was uploaded onto the Internet."
"The scalability of Mandiant Advantage deserves a ten out of ten."
"It is so valuable to have someone performing these functions outside of our business hours when we don't have staff in the building. We've seen a lot of solid metrics on the amount of malware that it's detecting and resolving. We're pleased with it so far."
"I have never faced stability issues."
"The advantage of the solution is being able to go look up threat actors and get a lot of detailed information about different attacks and different tactics and general information about threats."
"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."
"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."
 

Cons

"Collaboration of data in my view becomes a bit clogged, requiring effort to understand visually."
"Mandiant's on-prem client is too processor-intensive, so it's putting a strain on the local device's CPU. When a scan is running on the device, the other processing tasks slow to a crawl. We're still trying to figure out the correct settings for the client."
"They could have better support. Now that they've merged, they are moving towards a portal system, which isn't very helpful."
"I think that the data query that is used for data cloud language should be improved. It's really hard to query actual data from the platform."
"Sometimes Mandiant Advantage becomes noisy when dealing with widely recognized companies due to false positives."
"I have already given them feedback that their UI needs improvement since sometimes there is a lag. The side-by-side depiction of request response and action clogs the screen."
"Sometimes Mandiant Advantage becomes noisy when dealing with widely recognized companies due to false positives."
"Further integration across different Microsoft products would be an improvement."
"The integration is not as seamless compared to competitors like Palo Alto."
"With Microsoft, support is always crazy, it's not easy to get support."
