Deployed for vulnerability, configuration and compliance assessments by more than one million users across the globe, Nessus has become the industry standard. Nessus prevents network attacks by identifying the vulnerabilities and configuration issues that hackers use to penetrate your network. Nessus features high-speed asset discovery, configuration auditing, target profiling, malware detection, sensitive data discovery, and more. It supports more technologies than competitive solutions, scanning operating systems, network devices, next generation firewalls, hypervisors, databases, web servers, and critical infrastructure for vulnerabilities, threats, and compliance violations.

Tenable Network Security's team of research engineers keeps the Nessus® vulnerability scanner up to date with the latest network and host security audits available. Nessus includes the latest security tests for publicly available security patches, disclosed vulnerabilities, and common worms.

Nessus subscribers can also audit their UNIX and Windows servers for compliant configurations. Tenable provides several audit policies based on public best practices for hardening UNIX and Windows servers from the NSA, NIST (FDCC), CERT, and Center for Internet Security, and new policies can be easily created. A Nessus subscription also includes commercial email/live chat support and a customer support portal for use with the Nessus vulnerability scanner.
