I security testing is no longer optional. The EU AI Act deadline is August 2, 2026. OWASP published the Agentic AI Top 10 in December 2025. And the most popular open-source LLM testing tool just got acquired by OpenAI. We needed a vendor-neutral alternative. So we built **[Tessera](https://github.com/tessera-ops/t...)** — an open-source framework that runs 42 automated OWASP security tests against any AI model or agent.
