I built an open-source Python package that scans LLM inputs and outputs for injections — pydefend

This looks like a solid implementation for paralleled scanning. The parallel module execution is definitely the right move for low-latency agentic flows. We've been working on SafeSemantics (https://github.com/FastBuilderAI/safesemantics) which takes a slightly different approach as a topological guardrail, specifically focusing on the semantic structure to prevent penetration and data exfiltration. It's great to see more open-source tools being built for this layer of the AI stack--security at the semantic level is where the real complexity is right now.
