Free LLM security audit

I built Arc Sentry, a pre-generation guardrail for open source LLMs that blocks prompt injection before the model generates a response. It works on Mistral, Qwen, and Llama by reading the residual stream, not output filtering. Prompt injection is OWASP LLM Top 10. Most defenses scan outputs or text patterns, by the time they fire, the model has already processed the attack. Arc Sentry blocks before generate is called. I want to test it on real deployments, so I’m offering 5 free security audits this week.
