Brand threats have been monitored proactively and intelligence now drives daily security decisions
I am an end user of Mandiant Advantage. Mandiant Advantage's intelligence is good, and their service is good, but the price they charge is just too high. It's not that they're not supplying what they're selling; it's simply that the price is high, and putting a tag on that cost is somewhat problematic. I would rate Mandiant Advantage an 8 out of 10. I do not consider Mandiant Advantage an affordable solution at all. The prices are very high and very expensive. The price of Mandiant Advantage is not justified. It's really expensive, and it's so expensive that I'm not sure I will continue next year with their service.

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

"I have never faced stability issues."
"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."
"The live IOC feed identifies the type, technique, and tactics used."
"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."
"Mandiant Advantage has helped me enhance operational efficiency overall because it enriched our SIEM, which is Splunk, and the YARA rules I wrote within the platform help me understand better what my threat landscape is."
"The scalability of Mandiant Advantage deserves a ten out of ten."
"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."
"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

"Mandiant Advantage's platform itself is not good yet. They have many bugs because they changed the platform, so from time to time it's simply not working at all."
"Sometimes Mandiant Advantage becomes noisy when dealing with widely recognized companies due to false positives."
"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."
"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."
"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."
"They could have better support. Now that they've merged, they are moving towards a portal system, which isn't very helpful."
"Collaboration of data in my view becomes a bit clogged, requiring effort to understand visually."
"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."
"Further integration across different Microsoft products would be an improvement."
