This platform has a lot of potential but requires some dedicated resources to get the most out of the tools. Additionally, the value is low unless you buy multiple integrations.

    We have weekly meetings with our Reliaquest rep who does a great job guiding our partnership in the right direction. I only rated them as a 3 in delivery and execution because Reliaquest has had some issues with completing tuning requests in a timely manner.

ReliaQuest GreyMatter Likes & Dislikes

Like

ReliaQuest GreyMatter is compatible with many popular security products. The GreyMatter platform ingests all the logs into one location and generates security alerts based on the detected threats. In addition to the alerts, GreyMatter also utilizes AI to generate additional information, such as recommended actions to take based on the threat. My personal favorite feature of GreyMatter is the automated response plays (ARPs). With the ARPs, actions such as blocking IPs or disabling accounts can be automatically taken depending on what is detected. This allows for threats to be immediately shut down, rather than losing time to manually take action.

Like

Flexibility to pivot between different integrations and seamlessly close offense.

Like

What I like the most about the service is how responsive and eager the agents are. When there is an issue, escalation, or tuning, the staff is great at helping.

Dislike

ReliaQuest GreyMatter is very expensive. It can be very costly, if not impossible for smaller businesses to afford it. Connecting all the log sources is also a major project. You can expect to spend hours, as well as meeting with ReliaQuest's engineers, to make sure everything is set up correctly. The GreyMatter mobile app can be finicky at times. Occasionally I am not able to run response plays from the mobile app and have to use the desktop version instead.

Dislike

Fairly basic threat intelligence and inability to customize your own rules / detections. Everything must be run through RQ team.

Dislike

What I dislike the most is sometimes IP's are misidentified, but no overall big complaints.
