Tenable adds multistep reasoning and MCP support to Hexa AI agent

Exposure management company Tenable Holdings Inc. today unveiled new capabilities for Hexa AI, the agentic engine inside its Tenable One Exposure Management Platform, pushing the tool into general availability with multistep reasoning and Model Context Protocol support that the company says can shrink the gap between vulnerability discovery and remediation.

The announcement was made at Tenable’s Exposure 2026 conference in Boston. Tenable is pitching the update as a response to a security workflow problem that has worsened as frontier artificial intelligence models accelerate vulnerability discovery. The company argues that manual remediation processes cannot keep pace with discovery cycles now measured in minutes rather than months, leaving organizations exposed.

Hexa AI sits as an orchestration layer on top of the Tenable Exposure Data Fabric, the company’s repository of contextualized exposure data. It connects to existing security and information technology tools and lets customers either deploy Tenable’s prebuilt agents or build their own. The end goal, according to the company, is automating workflows that run from discovery through to remediation without security staff stitching context together by hand.
