Reverse Proxy GUARD

rpGUARD

Free100% offlineWindows · .NET 10

rpGUARD (Reverse Proxy GUARD) is a security-first reverse proxy. It sits in front of your web servers, inspects and filters incoming requests, then relays them to your backends — the role of an nginx, HAProxy or mini-Cloudflare. The engine runs in-process (Kestrel), no external binary.
