AegisGate is an asynchronous, high-performance MQTT proxy built in Rust, designed to protect downstream IoT brokers (like EMQX) from malicious actors and traffic surges.
Acting as a secure perimeter, it performs deep packet inspection, strict protocol validation, and per-IP rate limiting before allowing connections to pass through to the broker. This ensures that only authorized, well-formed machine data reaches the infrastructure, preventing DDoS attacks and resource exhaustion while maintaining zero-copy, high-concurrency I/O via the Tokio runtime.
