Launching Tuesday - what security layer do you use for LLM API calls?

We're launching OpenClaw LLM Proxy on Tuesday at 12:01 AM PDT - a drop-in OpenAI API replacement with built-in PII scanning and injection detection.

Curious to hear from the community before we go live: when you send prompts to OpenAI/Anthropic/Google, is there anything scanning for sensitive data before it reaches the provider?

Would love early feedback from anyone running LLM calls in production.
