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

Sophos MDR needs better threat intelligence, automation, integration, reporting, support, pricing, third-party compatibility, zero-day protection, and user communication.
Focus on including internal identifiers in alerts and onboarding templates to improve user experience and reduce setup time.
Introducing more detailed and customizable reporting and analytics features could help organizations better understand their security posture and the effectiveness of the MDR service.

The critical part is there, which we use, while most other functionalities we don't require because the more complicated the configuration we do in a security fabric, the more difficult it is to handle those types of data and readings and analytics.
Chief Technology Officer at Litmus
If they integrate those as well, it would be more reliable for us.
Project engineer at IT Solution india private limited
It is worth it for accurate triage later, but a template for common upload patterns will shorten that time.

Yati Gharat - PeerSpot reviewer
Chief Technology Officer at Litmus
Integrated analytics have improved threat visibility and reduced manual monitoring effort
One of the areas for improvement in Sophos MDR is the amount of traffic and the VPN because when we have that much load, the hardware gets a little bit heated. So they need to look into the capacity of the hardware. Functionality-wise and features-wise for Sophos MDR, we are somewhat satisfied, but there are a lot of things we don't use even. However, the critical part is there, which we use, while most other functionalities we don't require because the more complicated the configuration we do in a security fabric, the more difficult it is to handle those types of data and readings and analytics. We have enabled only the features and functions needed, leaving the rest disabled.
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.
