tenable

Tenable, Inc. is an American cybersecurity company that specializes in vulnerability management and exposure analytics. The company develops software that helps organizations identify, assess, and remediate security vulnerabilities across on-premises IT, cloud, and operational technology environments. Tenable's products are designed to provide continuous visibility into asset inventories, misconfigurations, and threat exposure, enabling risk-based prioritization and remediation workflows.

The best-known product family includes Nessus, a widely deployed vulnerability scanner, along with cloud-based Tenable.io and on-premises Tenable.sc for larger-scale vulnerability management and compliance. Nessus provides rapid scanning of endpoints and data centers; Tenable.io and Tenable.sc extend those capabilities to asset discovery, agent-based assessment, configuration auditing, and prioritized remediation across complex environments. The platforms integrate with security information and event management (SIEM), ticketing, and automation tools.

Tenable, founded in 2002, grew into a leading provider of vulnerability management solutions. It went public in 2018 on the NASDAQ under the ticker TENB and operates globally, serving industries such as finance, government, healthcare, manufacturing, and technology. The company emphasizes risk-based scoring, including its Vulnerability Priority Rating (VPR) to help customers prioritize remediation efforts based on exploitability, asset criticality, and exposures.

Tenable continues to expand into cloud, container, and OT security, offering scalable solutions for continuous monitoring, policy compliance, and incident response.
