How Shield works
DNS-level protection that works across all apps. No battery drain, no speed loss.
Your device sends a DNS request
Every time you visit a website or open an app, your device sends a DNS request to look up the server address. Shield intercepts these requests securely.
Shield checks the domain
Our DNS resolver checks the requested domain against a blocklist of 100,000+ known ad networks, trackers, and malicious domains, updated daily.
Bad requests are blocked silently
Ads, trackers, and threats are blocked before they ever reach your device. Legitimate traffic flows through with zero delay. All queries are encrypted.
Ads & trackers are blocked at the DNS layer. Safe traffic passes through normally.
Works on every device
Shield uses standard DNS-over-HTTPS, supported natively on iPhone, iPad, and Android.
