Hey PH, I'm Hamid — building open-source security tooling for LLMs

Hi everyone — I'm Hamid, a software engineer with a bit over a decade of experience. The last few months I've been heads-down building AEGIS: an open-source (Apache 2.0) defense-in-depth layer for LLM apps and agents — prompt injection detection, policy enforcement, and tool/agent permissioning so a prompt injection can't quietly get an agent to misuse a tool.

What pulled me into this specifically: most guardrail tooling I looked at only reports how it does against a static, round-one test set, which doesn't tell you much about what happens once an attacker actually adapts. So I built an adaptive red-teaming harness alongside the defense layer itself, and published the honest result even though it wasn't flattering.

Launching on Product Hunt this Tuesday. Mostly here to learn from others working on similar problems — what's everyone else building or running into on the LLM security / agent safety side?
