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.

Unified security monitoring has reduced alert fatigue and improves proactive threat hunting
I use real-time monitoring in ReliaQuest GreyMatter, which significantly improves my security posture. The unified interface helps reduce alert fatigue. I would estimate it saves around 20% in alert fatigue reduction. The automated threat hunting capabilities in ReliaQuest GreyMatter help me stay ahead of threats. The machine learning algorithm benefits my threat intelligence by providing deeper insights and predictions. I use various metrics to rate the success of the predictive threat intelligence in ReliaQuest GreyMatter.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Once we introduced Rapid7 MDR along with their vulnerability assessment tool, IVM, we transitioned from using Qualys and Tenable, which are top-tier tools in the market, because the management tool from Rapid7 allows us to access a variety of vulnerabilities in real time to fix them effectively."
"We've filled in crucial gaps we had with our previous solution. This was a key factor in choosing Rapid7 during the selection process. The ROI is already starting to show, too."
"The features of Rapid7 MDR that I find most effective for threat detection are the threat intelligence capabilities because it already collects many vulnerabilities and exploitations, as well as the configuration of network devices."
"The product allows us to customize our alerts."
"The enrichment that Rapid7 MDR generates for the client is greater than with other tools, and this has had a big impact."
"The benefits that came with Rapid7 MDR is the analysis we are getting now, which is quite useful."
"From my perspective, Rapid7 MDR is a really good product that is easy to implement and use."
"ReliaQuest GreyMatter saves around 60% of time or resources."
"ReliaQuest GreyMatter has helped us to reduce security incidents by 89%, which is a significant amount of incidents we have seen."
 

Cons

"There are potential improvements in reports and dashboards."
"However, I think the best area for improvement is pricing."
"The product should provide full transparency in security operations."
"We currently come across more false positives. The tool is a bit more aggressive than other tools."
"Evaluating the customer service and technical support teams of Rapid7 MDR, I would rate them a six out of ten."
