Agentic AI Defense: Tenable's CyberAgents Exchange and the Shift Toward Automated Operational Plumbing
At Black Hat USA 2026, security researchers and industry leaders, including Tenable and Anthropic, demonstrated a paradigm shift from high-level automation to agentic security engineering. While attackers are utilizing LLMs to reduce the cost of exploitation to 1990s-era levels, defenders are deploying agentic reasoning to solve critical operational toil. Key technical developments include the CyberAgents Exchange—a vendor-agnostic registry for AI agents and Model Context Protocol (MCP) servers—and specialized tools like Chokepoint Finder, which uses agentic orchestration to compress thousands of vulnerability findings into high-impact remediation actions. This evolution focuses on democratizing security engineering and automating the "connective tissue" of defensive operations.
