Nessus

The most trusted vulnerability assessment solution

Overview

What Nessus does

Nessus is the world's most deployed vulnerability assessment solution. It helps security professionals identify vulnerabilities, misconfigurations, and compliance issues across IT infrastructure.

What people use it for

  • Scanning hosts and applications for known vulnerabilities and misconfigurations
  • Running compliance and configuration audits against a defined scope

The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Nessus.

  • Nessus Professional is $4,790 for one year, with no free or low cost commercial tier
  • Multi year terms are the only discount route, at $9,330.95 for two years and $13,637.54 for three
  • It is a single user scanner, so team workflows mean migrating to another Tenable product
  • Tenable One vulnerability management is priced separately, starting at $3,500 a year for 100 assets

Cross-shopped

What people choose instead of Nessus
