Rapid7 MDR has provided a clear return on investment by significantly reducing the time my internal security team spends on alert triage through validated investigations and actionable recommendations.

Log triage no longer takes up our security team's calendar, allowing those hours to go into platform architecture, our DRM protections, and proactive hardening.
SEO And Outreach Specialist at a tech vendor with 11-50 employees
Each alert comes with the caller, the endpoint, and the queries, so we do not dig through logs.
Internet Marketing Manager at a tech vendor with 51-200 employees
I have seen a return on investment, mainly in time and not having to build a team, as we did not need to hire a security team to get around-the-clock cloud coverage.

Room For Improvement

Rapid7 MDR needs improved AI, cost structure, transparency, and ease of use, while enhancing integrations, reporting, and automation.
Focus on including internal identifiers in alerts and onboarding templates to improve user experience and reduce setup time.
There should definitely be a tool that gives us the confidence that whatever AI model we are using is secured through that tool.
Senior Technical Service Engineer Expert at a tech vendor with 10,001+ employees
For example, during a suspicious endpoint activity alert, the Rapid7 MDR team provides context around the process execution, related user activity, and supporting indicators, which help us quickly validate the incident and take appropriate actions.
Soc Analyst at a manufacturing company with 10,001+ employees
Rapid7 MDR is currently weak in AI solutions and intelligence, which is concerning.

It is worth it for accurate triage later, but a template for common upload patterns will shorten that time.

The setup and daily use have both been smooth.
BD with 10,001+ employees
Showing the customer name in the alert would help.

Valuable Features

Rapid7 MDR provides automated threat detection, AI-driven analysis, and 24/7 monitoring, enhancing security with minimal false positives.
UnderDefense offers anomaly detection, noise filtering, proactive reporting, 24/7 support, AI accuracy, governance, and efficient alert triage.
While a competitor's solution failed to detect many attacks, Rapid7 identified them in real time, which effectively pushed my management towards choosing Rapid7 MDR.
Manager SOC at PTCL
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.
Systems Administrator at a consultancy with 51-200 employees
The best features that Rapid7 MDR offers are 24x7 alert monitoring, expert threat hunting, and high quality alert validation, which significantly reduces false positive alerts.
Soc Analyst at a manufacturing company with 10,001+ employees

It has full-time support 24/7 with proactive reports, and monitoring runs around the clock.

Featured Reviews

Ehsan Khaleel - PeerSpot reviewer
Manager SOC at PTCL
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.
Ivan Voitovych - PeerSpot reviewer
Founder at Urlicer
AI-driven SOC triage has transformed threat monitoring and keeps our security work focused
The best features UnderDefense offers include mostly triage in-context signals read together across my stack, where one finding replaces many separate checks. A good thing too is its false positive suppression, as I do not get false notifications. Normal activity such as traffic spikes during customer events is recognized and documented, and only the unusual cases reach me. It has full-time support 24/7 with proactive reports, and monitoring runs around the clock. Reports and alerts come to me without even noticing or asking, so it is very useful. My team sees what happened without having to chase it. I find the proactive reporting and 24/7 support to have definitely made a real difference. Proactive reports mean I hear about what happened without having to ask, so I know the state of things at the start of the day, and 24/7 support matters most for traffic spikes and other events outside busy working hours, as I get an answer when I need one without keeping someone on call just in case, saving me a lot of time. Together, they let my team stay on infrastructure work and step in only when a decision is needed. Regarding UnderDefense's AI capabilities, I think the governance and security is the best there is, as the decisions that matter stay with my team and each finding is documented, allowing me to review afterwards how a conclusion was reached. That control and traceability is what I need from AI in a security role. The accuracy and reliability of UnderDefense's AI output is accurate and steady, as findings have matched what I saw when I checked them, and the pattern assessments are consistent, especially during large traffic events or spikes, which is when I depend on them most. When a case needs judgment, the reasoning is there so I can confirm it myself.
