Chainguard Harness Launches AI-Driven Vulnerability Detection Tool

• •Chainguard Harness uses frontier AI to detect exploitable vulnerabilities in real-time.
• •The tool builds applications in isolated environments to ensure accurate vulnerability findings.
• •Available through the Claude Marketplace, it provides tailored fixes for both open source and proprietary code.

On October 14, 2026, Chainguard announced the launch of Chainguard Harness, a new tool that utilizes frontier AI models to identify and remediate exploitable vulnerabilities in application code. The tool builds applications from source code in an isolated microVM environment, allowing a frontier model to probe for vulnerabilities in a live instance. Each identified vulnerability is reproducible and comes with a tailored fix, reviewed by Chainguard staff. This tool aims to alleviate the burden on security teams by providing proven findings rather than unverified alerts. Organizations can access this tool through the Claude Marketplace by Anthropic. Chainguard Harness is designed to enhance security for both open source and first-party code, addressing issues that traditional static code scanners often miss. The tool is expected to help teams find and fix vulnerabilities before they lead to incidents, particularly in critical infrastructure software.
