Most MDR providers treat Microsoft Defender and Sentinel as "another integration." Ontinue is built around them — the MXDR service of choice for organizations that want to extract maximum value from Microsoft E5 Security rather than duplicating the investment with a parallel SOC stack. Microsoft Security MSSP of the Year for a reason.
Ontinue ION is an MXDR service purpose-built on the Microsoft security stack — Defender for Endpoint, Defender for Identity, Defender for Cloud Apps, Sentinel, Entra. They operate as a 24/7 extension of your team, with a uniquely Microsoft-native delivery model: real-time collaboration over Microsoft Teams, automation tuned to Microsoft signals, and Agentic AI that accelerates investigations using the same data Microsoft already has on your environment.
You've paid for Defender for Endpoint, Identity, Cloud Apps, Sentinel. Ontinue is how you get more value out of that than rolling your own SOC against the Microsoft consoles.
Ontinue's pitch includes the case for going to E5. If you're on E3 today and considering MDR, an Ontinue brief frequently reframes the spend as a Microsoft modernization decision.
Ontinue supports non-Microsoft signals but it's not the lead story. If you're a Google-first or Linux-heavy shop, eSentire or CyberMaxx is the right brief.
If your roadmap is "decouple from Microsoft," anchoring your MDR to that stack is a step backwards. Brief vendor-neutral options instead.
