The Tenable Alternative with Unlimited Scanning
Replace Tenable.io, Tenable.sc, or Tenable Nessus with flat-rate vulnerability scanning that does not charge per asset. ScanAnchor includes CISA KEV and EPSS threat intelligence on every finding, auto-mapped compliance for PCI-DSS, Cyber Essentials, ISO 27001, and SOC 2, plus native Jira and ServiceNow integrations at roughly 15% of Tenable.io list price.
Why Teams Leave Tenable
Tenable.io charges £30–£65 per asset per year. At 500 assets, that is £15,000–£32,500 annually. At 2,000 assets, £60,000+. ScanAnchor is flat-rate: £179/month for unlimited assets and unlimited scans. Every new cloud workload, container, or ephemeral instance raises your Tenable invoice but changes nothing on ScanAnchor.

Where Tenable Still Wins
Tenable.ot is purpose-built for operational technology and industrial control systems (SCADA, PLCs, HMIs). Tenable.sc runs fully on-premises for air-gapped classified networks. If those fit your scope, Tenable remains the better tool.
