Best Free Managed Detection and Response (MDR) Services of 2025

Guardz is the unified cybersecurity platform purpose-built for MSPs. We consolidate the essential security controls, including identities, endpoints, email, awareness, and more, into one AI-native framework designed for operational efficiency. Our identity-centric approach connects the dots across vectors, reducing the gaps that siloed tools leave behind so MSPs can respond to user risk in real time. With 24/7 AI + human-led MDR, Guardz utilizes agentic AI to triage at machine speed while expert analysts validate, mitigate, and guide response, giving MSPs scalable protection without adding headcount.

By collaborating, we can effectively combat cyber attacks at every endpoint, throughout the entire organization, and wherever the conflict unfolds.
