Guard Core

One API security engine. Every framework. Live telemetry.

Guard Core is application-layer API security: one framework-agnostic engine with thin per-framework adapters. The open-source layer does IP control, rate limiting, signature-based attack-pattern detection, security headers and behavior tracking — production-ready for Python (FastAPI, Flask, Django, Tornado) and TypeScript (Express, NestJS, Fastify, Hono), Rust in progress. A telemetry agent streams events to the cloud dashboard for real-time monitoring, threat intel and triage.
