What you would be giving up
Tenable Nessus is most often brought in for vulnerability scanning of servers, network devices and web applications, configuration and compliance auditing against hardening benchmarks, point in time assessments by consultants and penetration testers. Anything replacing it has to cover the ones you actually depend on, and a cheaper tool that misses one of them is not cheaper.
Two things this page cannot settle. It compares on price, model, tier count and rating, because those are the fields the category listing carries, feature-level differences need both full records, which is what the head-to-head pages load. And the ratings are third-party aggregates imported with each entry rather than reviews written here, so a 0.2 difference between two tools is noise rather than a finding.
If Tenable Nessus is broadly right and the question is cost, the Tenable Nessus pricing breakdown covers every tier and what each one adds. If you want the whole field rather than a shortlist, the Cybersecurity category lists everything the directory holds, and best cybersecurity tools ranks them.
Tenable Nessus runs on windows, linux, macos, cloud. Platform coverage is not carried on the category listing for the alternatives, so it is one more thing to check on each head-to-head page rather than here.
