Tenable

Tenable is a cybersecurity company founded in 2002 by Ron Gula, Jack Huffard, and Renaud Deraison, headquartered in Columbia, Maryland, US. Building on the Nessus vulnerability scanner, the company set out to give organizations a continuous view of risk across IT, cloud, operational technology, and identity systems rather than periodic scan reports.

Its Tenable One platform unifies vulnerability management, cloud security, identity exposure, and OT security into a single exposure management workflow, using an AI assistant called Hexa to help teams prioritize and remediate findings. Organizations in finance, energy, healthcare, education, and government use the platform to reduce the attack surface across hybrid environments.

1. Vulnerability Management: Continuously scans IT assets to identify and prioritize exploitable weaknesses.

2. Cloud Security: Assesses multi-cloud configurations and workloads for misconfigurations and risk.

3. Identity Exposure: Detects privilege and identity misconfigurations that enable lateral movement.

4. OT Security: Monitors industrial control systems alongside IT assets in a single inventory.

5. Hexa AI Assistant: Automates triage and remediation guidance across the exposure management workflow.

6. Tenable One Platform: Consolidates exposure data from across domains into one prioritized risk score.
