Chainguard announced Harness, a service that builds and probes a customer application in an isolated environment, reproduces findings and has a Chainguard engineer review proposed fixes. It says enterprise customers can procure it through Claude Marketplace using Anthropic commitments, while the same release also directs users to a beta waitlist. It uses Anthropic models; Chainguard did not train a new model.
