Expose What CAASM Can't
ReliaQuest GreyMatter Discover empowers security teams to move beyond observation and resolve hidden risk proactively across their attack surface.

You Can't Protect
What You Can't See
Unlike traditional attack surface management tools that operate in silos with limited visibility and actionability, GreyMatter Discover is a native part of the GreyMatter agentic AI security operations platform. This connection gives Discover more access, greater visibility and richer context.
