Comprehensive detection has strengthened real-time protection and streamlined investigations
My experience with detection and response capabilities for Microsoft-centric environments has been positive. While API integration can be challenging with some third-party tools, Microsoft's built-in features facilitate seamless communication. I have found it relatively easy to triage and integrate Microsoft systems with Rapid7 MDR. In terms of digital forensics and incident response included in the MDR service, my experience is that it is not very robust. We lack a dedicated forensic team, which is essential for thorough investigation. Rapid7 has introduced honeypots, which is an encouraging feature, but it is not a comprehensive solution such as those offered by competitors, such as Palo Alto's Unit 42. Apart from forensics, I believe Rapid7 MDR should introduce more forensic services. Another area to improve is the active platform's handling of on-premises tools versus cloud-based tools. We prefer on-premises options for data security, and we find limitations in features compared to cloud-based tools, concerning data access and privacy controls.

Improved threat detection has reduced incidents and has automated investigations with AI
There are multiple features of ReliaQuest GreyMatter which I love personally. The agentic AI, which helps in autonomous investigation and containment, is multiplying the speed of the task to be done. Features such as managed service integration and MDR with human expertise when needed are some major features which I love about ReliaQuest GreyMatter.
