Leak protection is the set of features that prevents traffic from escaping the VPN tunnel - especially DNS, IPv6, and WebRTC leaks. A strong implementation includes forced VPN DNS, firewall-level blocking of off-tunnel DNS, safe handling of IPv6, and robust behavior during reconnects and network transitions. Leak protection also covers edge cases like captive portals, sleep/wake cycles on laptops, and “always-on” mobile behavior. Users who prioritize privacy should treat leak protection as non-negotiable: encryption alone is not enough if name resolution or secondary protocols leak identifying data. To validate leak protection, test after installation and after every major OS update: check DNS servers, IPv6 status, and WebRTC exposure while the VPN is active. In DVPN designs, leak protection becomes even more important because routing may change across nodes; the client must enforce tunnel-only policies consistently. Combine leak protection with a kill switch for a best-practice baseline.
