Product Manager at Flash5.0I found ReliaQuest GreyMatter excellent for threat detection, reducing incidents by 89% via its AI agents and holistic visibility. Setup was easy and support great, though I believe the UI could improve.
Senior Security Analyst at Tata Consultancy4.5I use ReliaQuest GreyMatter for detection, XDR, and SIEM. It's efficient, saving me 60% of resources, and offers strong real-time monitoring and automated threat hunting. Despite some UI and integration needs, I find it cost-effective, stable, and scalable.
