Tenable Nessus vs UpGuard
Side-by-side comparison of features, pricing, ratings, and alternatives.
Nessus is Tenable's vulnerability assessment scanner, used to discover vulnerabilities and misconfigurations across operating systems, network devices, and applications. It covers over 117,000 CVEs through more than 319,000 detection plugins, with roughly 100 new plugins released weekly, and prioritizes findings using CVSS v4, EPSS, and Tenable's own VPR risk scoring. The product ships with 450+ pre-built policy and compliance audit templates and guided remediation workflows to help teams act on results rather than just collect them. Nessus Professional and Nessus Expert are sold as annual subscriptions, with Expert adding external attack surface scanning and expanded web application scanning.
UpGuard is a cyber risk posture management platform that helps organizations identify and reduce security risk across their vendor relationships, attack surface, and internal workforce. It continuously scans a company's external digital footprint to surface exposed assets, misconfigurations, and vulnerabilities, and produces security ratings that can be used to benchmark and monitor third-party vendors over time. The platform is used by over 45,000 companies across financial services, healthcare, technology, and education, and includes a Trust Exchange feature that automates security questionnaire handling between organizations and their vendors. Additional modules cover user risk management, including shadow AI usage monitoring, with automation workflows for discovery, notification, and remediation driven through its API.
