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

"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."
"From my perspective, Rapid7 MDR is a really good product that is easy to implement and use."
"The benefits that came with Rapid7 MDR is the analysis we are getting now, which is quite useful."
"Overall, Rapid7 MDR helps us to strengthen our security operations by providing continuous monitoring, high quality threat detection, and expert analysis support."
"Rapid7 MDR is an excellent choice for organizations that want enterprise-grade threat detection and response without building a 24/7 in-house SOC team, combining expert analysis, high fidelity detections, broad integration support, and actionable incident response."
"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."
"Despite the pricing being a consideration, I always recommend Rapid7 MDR first."
"The main benefits that Rapid7 MDR provides for me as an end-user are the security and that they are available 24 hours a day, always."
"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 still a couple of areas where Rapid7 MDR can be improved. The visibility of the dashboard should be improved, and faster threat detection can also be enhanced."
"Evaluating the customer service and technical support teams of Rapid7 MDR, I would rate them a six out of ten."
"We cannot allow it to go outside because we do not have that level of trust at the moment."
"AI is present, and I think Rapid7 MDR could add good reporting, more reporting, and perhaps more templates in the future to make the product even better."
"Regarding Rapid7's support team, I must say that their response time is not as quick as I would prefer. While they do respond, it can take a few days or even a week to get on a call."
"The price of Rapid7 MDR could definitely be lower, as these are expensive systems, especially if you have the MDR."
"I think Rapid7 MDR already has a strong managed security service, but I believe things can be improved."
"We currently come across more false positives. The tool is a bit more aggressive than other tools."
"Areas that have room for improvement include user interface and integration."
