Tenable Pricing (2026)
It's a split system: Nessus (Professional and Expert) is sold as a per-scanner license with a fixed annual fee you commit to for 1-3 years, while Tenable One products are quoted based on assets under management (IPs, workloads, apps). You're not paying for users, you're paying for how much attack surface you're scanning.

AI Pricing Analysis
Pricing Model
It's a split system: Nessus (Professional and Expert) is sold as a per-scanner license with a fixed annual fee you commit to for 1-3 years, while Tenable One products are quoted based on assets under management (IPs, workloads, apps). You're not paying for users, you're paying for how much attack surface you're scanning.
Tier Strategy
Nessus Professional is built for individual pentesters or small security teams doing point-in-time vulnerability scans. Nessus Expert adds external attack surface and cloud scanning for consultants who need to cover more than internal infrastructure, and the jump happens the moment a customer asks you to assess their cloud or web-facing assets. Tenable One is the enterprise leap — it's for teams that need continuous exposure management across the whole org, not just a scanning tool one analyst runs manually.
Competitive Positioning
Nessus has been the default vulnerability scanner for years, so it's priced as an accessible entry point compared to full platform plays like Qualys or Rapid7 — cheap enough that individual practitioners buy it out of pocket. Tenable One is where they compete for enterprise budget against Qualys VMDR and CrowdStrike Exposure Management, and pricing opacity there signals they're chasing six-figure platform deals, not self-serve buyers.
Growth Lever
The real paywall is scope: Nessus locks you into single-scanner, self-managed use, so growth comes from needing multi-user access, API automation, or broader asset coverage that only Tenable One provides. Multi-year discounts on Nessus are clearly designed to lock in solo users early, betting that some fraction convert into bigger exposure management contracts as their org matures.
