How It Works
Protection in milliseconds

Your device sends a DNS query to our anycast network. Our edge resolvers receive the request in under 5ms, no matter where you are.
Policy Evaluated
Our O(1) policy engine checks the domain against your rules, threat feeds, and content categories — all in a single Redis cache lookup.
