What’s actually different
Buyer brief
Updated 2026-03-08
Fit. On paper, these look close. Both offer 60-minute SLAs, $1M warranties and 100% MITRE ATT&CK detection. The real differences are in what's included in the base price and how much you can see.
Response. Sophos MDR Complete bundles unlimited incident response with no caps or extra fees. SentinelOne only includes IR in the Elite tier, not Essentials, so make sure you know which tier you're being quoted. Sophos assigns a dedicated IR lead during active incidents. SentinelOne's Elite tier gives you a Threat Advisor who becomes embedded in your security program.
Cost and scope. SentinelOne has the edge on MITRE validation. Beyond the platform evaluation, they also participated in the managed services evaluation, scoring 100% detection of 15 attack steps with the best signal-to-noise ratio among 11 vendors. Sophos's 2025 ATT&CK result covered 86 of 90 activities, but that tested the platform, not the managed service. SentinelOne gives full query access through the Singularity console with Purple AI for natural language search. Sophos provides dashboards only. On warranty terms, Sophos's $1M is a single-claim limit across all subscriptions. SentinelOne's covers $1,000/endpoint affected up to $1M per 12 months and resets annually.
