ReliaQuest GreyMatter Reviews Summary
Author infoRatingReview Summary
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.
Product Manager at Flash.co5.0I use ReliaQuest GreyMatter to unify SIEM, EDR, and cloud logs for fast threat detection; it caught a phishing attempt in five minutes. It cut incidents 89% and improved ROI. It’s stable, scalable, well supported, but the UI needs work.
