Tenable Nessus Professional

Tenable Nessus is the vulnerability scanner that security professionals have trusted for so long it's practically a verb in the industry. Nessus Professional identifies software flaws, missing patches, and misconfigurations across operating systems, devices, and applications with fast, accurate scans that eliminate the blind spots where threats love to hide. With over 450 pre-configured templates covering CIS benchmarks and compliance standards, you can go from installation to actionable results faster than most tools finish their initial configuration wizard.

Prioritization is where Nessus turns raw scan data into decisions. The platform layers EPSS (Exploit Prediction Scoring System), CVSS, and Tenable's proprietary VPR (Vulnerability Priority Rating) to surface the vulnerabilities that actually matter, not just the ones with scary CVE numbers. Live Results automatically performs offline vulnerability assessments with every plugin update, so you know about new exposures the moment they're published rather than waiting for the next scheduled scan window.

Nessus Professional is priced for consultants and lean security teams, offering unlimited assessments without per-asset licensing that penalizes you for having a large environment. Customizable reporting exports in formats tailored to your workflow, whether that's feeding a SIEM, briefing executives, or satisfying an auditor. For organizations that need comprehensive vulnerability visibility without the enterprise platform complexity, Nessus Professional delivers the scanning depth that built Tenable's reputation in a package that respects your budget.
