API Guardian
A security-first API gateway that protects external API usage, enforces policy at the edge, and gives teams full visibility into how their systems are actually used.
Why this exists
In most systems, client applications talk directly to third-party APIs. This exposes API keys, makes rate limits unreliable, and provides no clear way to detect abuse or failures.
As traffic grows, small issues become outages. One leaked key, one misbehaving client, or one spike can take the entire system down.
What API Guardian does
API Guardian introduces a dedicated gateway layer between applications and external APIs. It centralizes authentication, rate limiting, key isolation, and logging — without changing how clients behave.
Deployment
API Guardian is designed to run close to your infrastructure, giving you full control over security boundaries and performance.
Self-hosted (Docker)
Run as a container alongside your backend services.
VPS / Cloud VM
