A Mercurial Secure API Access Proxy stops that. It sits between your clients and your backend services, enforcing identity, permissions, and encryption at the edge. Every request passes through it. Every token is verified. Every route is checked against fine-grained rules before your application even sees the traffic.
Mercurial Secure API Access Proxy is built for scenarios where speed, consistency, and airtight access control matter more than anything else. It keeps latency low by handling authentication and authorization in-memory, close to the network boundary. It locks down APIs against brute-force attacks, replay attempts, and malformed payloads without adding complex middleware to your app code.
Deploying it shields internal APIs, third-party integrations, and microservices from untrusted traffic. Integration is straightforward: point your DNS to the proxy, set your API routes, and configure access policies in YAML or JSON. It supports JWT, OAuth2, and mTLS out of the box, with real-time revocation and custom claim checks.
