Envoy Filters

Envoy Filters are customizable tools used within the Envoy proxy to modify or enhance network traffic as it flows through the system. Think of them as filters on a camera or a kitchen sieve—they can inspect, change, or block data packets to meet specific needs. These filters allow organizations to add features like security checks, traffic routing, or data transformation without altering the core Envoy software. In essence, Envoy Filters provide a flexible way to tailor network behavior, ensuring the system adapts effectively to unique requirements while maintaining high-performance and reliability.
