Tenable

Tenable is a globally recognized cybersecurity company and the creator of Nessus, the world's most widely deployed vulnerability scanner. Founded in 2002 and headquartered in Columbia, Maryland, Tenable pioneered the concept of continuous network monitoring and has evolved into a comprehensive exposure management company, helping organizations understand and reduce their cyber risk across IT, OT, cloud, and identity environments.

Tenable Vulnerability Management (formerly Tenable.io) is the company's cloud-based platform for continuous vulnerability assessment and exposure management. The platform uses a combination of cloud agents, network scanners, and API integrations to discover and assess all assets in an organization's environment, from on-premises servers and workstations to cloud instances, containers, and web applications. Tenable's Predictive Prioritization technology, powered by machine learning, analyzes vulnerability severity, threat intelligence, and asset criticality to identify the three to five percent of vulnerabilities that are most likely to be exploited, enabling security teams to focus remediation efforts where they will have the greatest impact.

Tenable Security Center (formerly Tenable.sc) is the on-premises deployment option for organizations with compliance or data sovereignty requirements that prevent use of cloud-based security tools. Security Center provides the same comprehensive vulnerability assessment capabilities as Tenable.io in a self-managed environment, with advanced analytics, customizable dashboards, and API access for integration with existing security workflows.

Tenable OT Security (formerly Tenable.ot) provides passive and active assessment capabilities specifically designed for operational technology environments including industrial control systems (ICS), SCADA systems, and operational networks in manufacturing, energy, utilities, and critical infrastructure sectors. The platform identifies vulnerabilities, misconfigurations, and unauthorized changes in OT assets without disrupting production operations.

Tenable Cloud Security (formerly Accurics and Tenable.cs) provides cloud security posture management (CSPM), infrastructure-as-code security, and cloud workload protection across AWS, Azure, and Google Cloud environments. Nessus Professional continues to serve as the gold standard for penetration testers and security practitioners performing manual vulnerability assessments in authorized environments.
