What’s actually different
Buyer brief
Updated 2026-03-08
Fit. If you're already on SentinelOne and happy with the platform, the question is whether you want MDR from SentinelOne directly or from an independent provider who can follow you if you switch EDR later. Expel supports SentinelOne alongside CrowdStrike, Microsoft Defender, Carbon Black, Cortex, Elastic and Cybereason. Switching EDR doesn't mean switching MDR.
Response. Expel covers all six core response actions through API integrations. SentinelOne covers five, with no account disable through the MDR service. Both offer configurable approval and full query access.
Cost and scope. Expel publishes 14-minute MTTR for critical incidents with auto-remediation. SentinelOne claims 18 minutes against a 60-minute contractual SLA. Neither is independently validated. Expel communicates through Slack and Teams (Premium tier). SentinelOne uses portal and email. SentinelOne offers a $1M breach warranty and bundles IR in the Elite tier. Expel offers neither, and threat hunting is also a separate add-on. That cost gap narrows once you price Expel's add-ons against SentinelOne's platform prerequisite ($180-230/endpoint/year before the MDR bolt-on).
