Cost considerations

Nessus Professional uses a flat yearly license of roughly a few thousand dollars per scanner that covers unlimited assets and includes every plug-in, making costs predictable. That subscription is noticeably lower than per-asset pricing from Qualys or Rapid7 while still handling local, cloud, and web targets without paid add-ons. Costs rise only if multiple scanner seats are needed, so value is strong but not universally best-in-class.

Functionality

Nessus delivers dependable network, authenticated and agent scans, yet cloud and container coverage stays fairly basic. Findings come with standard CVSS scores, leaving security teams to decide risk and manually move results into ticketing systems. These capability gaps keep Nessus roughly mid-tier for overall functionality.

Compatibility

Nessus provides agents for Windows, macOS, and Linux and can scan AWS, Azure, and GCP when credentials are supplied. The absence of turnkey CMDB or SIEM connectors leaves teams depending on API scripts or CSV exports, placing compatibility squarely in the middle of the market.

User experience

Nessus offers a straightforward web console, but the look and feel lag behind newer cloud tools. Most users can run scans quickly, yet customizing templates and reports takes trial and error. Limited drill-downs or guided fix paths mean analysts spend extra time piecing details together.

Customer support

Nessus users receive rapid same-day business-hours help and can upgrade to 24×7 phone and web support, backed by detailed knowledge articles. Tenable’s research team pushes new scanning plugins several times per day, typically within hours of a CVE disclosure. Dedicated success managers are available only to larger enterprise contracts, so support is strong but not universally top-tier.
