Protecting your browsing from ISP surveillance
Every time you visit a website, your Mac sends a DNS query. This query reveals exactly which domain you're trying to reach — and by extension, what services and content you're accessing.
Standard DNS queries are sent in plain text. Your Internet Service Provider (ISP), network administrators, and anyone on the same network can see every domain you visit. This is a significant privacy concern in 2026.
LittleSnitch - Network Monitor for Mac supports modern encrypted DNS protocols including DNS over HTTPS (DoH), DNS over TLS (DoT), and DNS over QUIC (DoQ). These protocols encrypt your DNS queries, preventing ISP-level tracking and man-in-the-middle attacks.
