Harness launches AI agents for machine-speed vulnerability response

Harness has introduced a set of security capabilities designed to help security teams respond to vulnerabilities at machine speed. The new tools include AI SAST, agentic triage and remediation, a dedicated Zero-Day Agent, and virtual patching.

The company says attackers are using frontier AI models to exploit vulnerabilities in as little as six hours, while the average fix takes over 50 days. Harness claims its tools reduce the time from detection to deployment from weeks to hours.

The announcement follows Harness’s merger with Traceable in early 2025 and the launch of Agent DLC in July 2026, and includes new integrations with Kong and Google.
