SentinelOne Alternatives 2026: 6 Options, 3 Free
SentinelOne alternatives: CrowdStrike Falcon, Sophos, Microsoft Defender for Business, Wazuh and 2 more. Prices and licenses checked October 25, 2026.

Verdict:SentinelOne's Singularity Complete lists at $179.99 per endpoint a year and Commercial at $229.99, on a page that shows prices for 5 to 100 workstations and says the partner price controls. There is no free trial on that page, only a demo. If you only need a cheaper managed EDR, CrowdStrike's Falcon Go at $59.99 per device a year is the obvious price comparison. Microsoft Defender for Business is $3 per user a month and makes sense when you already pay for Microsoft 365. Sophos is worth a trial but publishes no numbers. For no-license-cost options, Wazuh covers detection and compliance monitoring if you can run the servers, and LimaCharlie's free tier handles two endpoints for testing. Velociraptor is a forensics tool, not a replacement for a prevention agent. The trade-off is automation. SentinelOne blocks and rolls back on the endpoint; Wazuh and Velociraptor need analysts to act on alerts. Stay if you lack security staff and depend on autonomous response. Leave if the per-endpoint price is the problem and you have someone to run open-source tooling or can accept a different vendor.
