Who shouldn’t buy Tenable Nessus / Tenable One?

A direct read on the buyers Tenable Nessus / Tenable One is the wrong fit for — sourced from the same editorial team that ranked the full Vulnerability Management Software category.

Worst for

Cloud-native-only shops (Wiz better agentless graph), Microsoft 365 E5-anchored shops (Defender VM bundled cheaper), or developer-first engineering-led security programs (Snyk better SCA fit).

For context: who it IS for

Large enterprises (1,000+ employees) wanting best-of-breed VM with the broadest scanner coverage, deepest auditor familiarity, and a credible exposure-management consolidation path via Tenable One.

Target size: 500–500,000+ · Large enterprises and regulated industries
