HTTP Route Leak Guard

HTTP Route Leak Guard is a networking routing control that detects and blocks accidental route propagation for application-layer request routing. It uses prefix filters, validation, and peer policy so teams can protect reachability while keeping evidence, reliability, and public-safe operational boundaries clear.

“The network engineering team used HTTP Route Leak Guard when a client retried a request, so the team could protect reachability before traffic crossed a service boundary.”
