Union.ai launches Vulnerability Harness for testing AI agents before they go live

Union.ai has added a "Vulnerability Harness" to its managed platform for building and running AI agents. The feature lets you run test cases against your agent workflows and see where they break — before you push to production.

Union.ai is a managed platform for building and running AI agents. It's aimed at teams that want to deploy agent workflows without managing the infrastructure themselves. The new Vulnerability Harness sits on top of that, giving developers a place to validate their agent logic with real test cases.

As more teams start shipping AI agents — customer service bots, internal automation, side projects — testing them has become a real problem. Agents behave differently from traditional code. They respond to language, context, and the data they pull in. The Vulnerability Harness is Union.ai's attempt to make that testing process less painful.

Why this matters for us: as AI agents move from startups to small businesses, the tools to test them safely are becoming more accessible — so teams without big engineering departments can try building without breaking everything.
