How It Works

Protection in milliseconds

Every DNS query is evaluated in real time against your policy. No agents. No software. No latency.

01

Query Received

Your device sends a DNS query to our anycast network. Our edge resolvers receive the request in under 5ms, no matter where you are.

02

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.

03

Response Returned

Allowed queries are resolved and returned instantly. Blocked domains return your custom block page. Every decision is logged to ClickHouse.
