The Verdict
SentinelOne is built for enterprise and security operations, with a focus on edr and xdr. Tenable targets security teams and compliance officers and leads with vulnerability-scanning and asset-discovery.
SentinelOne uses custom enterprise pricing, while Tenable starts at $3990/mo — a tangible advantage for teams with a fixed budget.
Tenable has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. SentinelOne requires a paid subscription from day one.
