What Tenable changed

• Added an announcement for Claude Mythos 5 coming to the Tenable One platform.
• Introduced a new "Adversary View" feature powered by this AI integration.
• Updated the homepage headline to focus on "Bringing the power of Mythos to Tenable One."
• Replaced a general AI exposure video with a new Mythos-specific homepage video.
• Swapped a product announcement about AI application security for the new Mythos 5 integration news.

Tenable is deepening its partnership with Anthropic to use advanced AI models. This move aims to give security teams an "Adversary View," helping them see their network the way a hacker would.

• The main headline changed from "AI threats can lurk out of view" to "AI-driven attacks can strike at any time."
• The value proposition shifted from keeping risk "in perspective" to keeping attacks "contained."
• Call-to-action buttons were updated from "Find out how" to "See why it matters."
• The background hero video was updated from a "fish" theme to a "lightning" theme.

The brand is shifting its tone from "observing" AI risks to "containing" active AI-driven attacks. This suggests they are positioning their product as a more aggressive, real-time defense tool rather than just a visibility platform.

• Added "CyberAgents Exchange" to the main navigation and top-level links.
• Changed the main AI headline from "AI agents can run wild. Tenable keeps them tamed" to "AI threats can lurk out of view. Tenable keeps your risk in perspective."
• Updated the call-to-action button for AI Exposure from "Get started" to "Find out how."
• Replaced the homepage background video (from "cat" to "fish").
• Added a link to the CyberAgents Exchange in the footer resources.

Tenable is shifting its AI security message from "taming" AI agents to managing "hidden threats." By launching an open-source registry for AI agents, they are positioning themselves as the central hub for AI security standards and visibility.
