What’s actually different
Buyer brief
Updated 2026-04-09
Fit. This comparison only applies if you're in a Microsoft ecosystem. Ontinue's ION MXDR runs exclusively on Microsoft Defender and Sentinel. SentinelOne runs exclusively on Singularity. Neither works with the other's stack, so you're choosing which ecosystem to commit to.
Response. Ontinue's standout claim is that its agentic AI resolves 99.5% of incidents without customer involvement. SentinelOne's Purple AI Athena adds automated triage and investigation but doesn't publish an equivalent automation rate. Ontinue communicates primarily through Microsoft Teams with an AI-powered chatbot. SentinelOne uses portal and email.
Cost and scope. SentinelOne publishes a contractual 60-minute response SLA and an 18-minute average MTTR. Ontinue publishes no formal SLA. SentinelOne scored 100% detection in MITRE managed services and platform evaluations. Ontinue has not participated in MITRE evaluations. Ontinue's data portability is stronger. Detection data and Sentinel analytics rules stay in your own tenant if you leave. SentinelOne's detection content is platform-specific and not portable. SentinelOne offers a $1M breach warranty and Windows Rollback for ransomware recovery. Ontinue offers neither. Ontinue requires Microsoft E5 or Defender licenses as a prerequisite, which adds to the total cost alongside Sentinel consumption charges.
