VPNVPN test results compared: kill switch failures, idle traffic and what apps leave behindOur own measurements of every app we have tested, side by side: kill switch failures, leaks, idle traffic, and what stays on your PC after uninstall.
VPNSurfshark review: quiet at idle, but its kill switch slips at startup 3.9/5The quietest VPN we've tested while idle, with no leaks in normal use. But the kill switch is off by default, our IP got out at startup, and uninstalling left an IPv6 block.
VPNNordVPN review: leak-proof, but the heaviest app we've tested 4.2/5No leaks in any test and the strongest kill switch we have tested. But it runs three always-on services, uses about 1 GB of memory and keeps calling its analytics server after you click Reject.
VPNProton VPN review: clean and quiet, but its kill switch leaked 4.3/5Clean install, quiet at idle and no leaks in normal use. But the kill switch is off by default, and the Standard mode let our real IP out for about 9 seconds when the VPN service crashed.
NetworkingZeroTier review: light and safe, with a messy uninstall 4.0/5Light, well-behaved and safe by default while installed. But uninstalling leaves the device's private key, network settings, a driver and two allow-all firewall rules behind.
