Scanners find missing patches, misconfigurations, and exposed services across servers, cloud accounts, and web apps. Risk scores combine severity with exploit activity and asset importance, and generative AI features summarize attack paths for analysts.
Nessus is widely used for individual scans, while Tenable One targets enterprise programs. Plans and pricing vary.
Qualys and Rapid7 are alternatives. Tenable suits cybersecurity analysts who run vulnerability programs.
