IronWarden is a Rust-based AI security reverse proxy that provides real-time PII redaction, prompt injection defense, and cryptographic audit logging for LLM streaming. It works as a transparent gateway for OpenAI, Anthropic, and Ollama clients with microsecond latency and zero application code changes.
A user in Amsterdam describes using Chisel, an open-source tool that tunnels TCP and UDP traffic over HTTP and WebSocket, to bypass their hotel's restrictive firewall that blocks WireGuard and other services. The article provides installation and configuration instructions for running Chisel as both server and client, including setup with a reverse proxy like Caddy.
