Is Tenable One suitable for small businesses?

Tenable One is primarily designed for mid-market to large enterprises with complex, hybrid environments. Small businesses may find it overly complex and expensive compared to standalone tools like Nessus Professional.

How does Tenable's AI, Hexa AI, work?

Hexa AI is an agentic orchestration engine that analyzes exposure data to prioritize risk and can automate remediation workflows. It acts as an AI co-pilot to guide security teams on what to fix first.

Can Tenable One integrate with our existing security tools?

Yes, Tenable One is built on an open platform with Security Tool Connectors to ingest data from third-party sources like SIEMs, EDRs, and other scanners, creating a unified exposure graph.

What is the Exposure Data Fabric?

It's Tenable's proprietary architecture that normalizes and correlates disparate security data into a single, queryable data layer. This enables the cross-domain attack path analysis that powers Tenable One's insights.

How is Tenable One licensed and priced?

Licensing is asset-based and typically requires a custom quote. It's subscription-based and priced for enterprise scale, often with different tiers for various security domains (e.g., cloud, identity, OT).

AI agents are the new "digital employees”, but no one’s vetting them | Tenable Co-CEO Steve Vintz

AI agents act like digital employees; reading data, making decisions, executing tasks with no human in the loop. But we don't vet them the way we'd vet a new hire. Tenable Co-CEO Steve Vintz joins Ticker News to unpack the AI governance gap, why regulation needs a risk-based approach, and the real-world attacks already testing it.
