Tenable Holdings Inc

Tenable Holdings, Inc. (Nasdaq: TENB) is an exposure management company. Its products identify and help close cybersecurity gaps across IT infrastructure, cloud environments, operational/critical infrastructure and, increasingly, AI tools, LLMs and MCP servers.

Its core offering is the AI-powered Tenable One Exposure Management Platform, which unifies security visibility, insight and remediation across the attack surface. Recent additions include:
- Tenable One Adversary View, powered by an integration of Anthropic's Claude Mythos.
- Tenable Hexa AI, an agentic engine running always-on fleets of AI agents that find exposures, orchestrate remediation and verify fixes.
- CyberAgents Exchange, an open-source, vendor-agnostic registry for AI agents, skills, MCP servers and multi-agent playbooks.

Tenable generates revenue mainly from subscriptions, which made up the large majority of the roughly $276 million in Q3 2026 revenue; recurring revenue was 95% of the total. Smaller revenue streams come from perpetual licenses with maintenance and from professional services. The company serves more than 40,000 customers worldwide, including enterprise and six-figure accounts. IDC has ranked it first in worldwide device vulnerability and exposure management market share for eight consecutive years. It is led by Co-CEOs Steve Vintz and Mark Thurmond, and its capital structure now includes $800 million of convertible senior notes and a $400 million secured revolving credit facility.
