All of the top VPNs on this list have a strict no-logs policy, meaning none of your online activity is ever stored by the service. Ideally, the VPN you choose will use RAM-based servers that cannot physically store logs, or it will have voluntarily undertaken a third-party audit to verify that it doesn’t keep any user data.
Overall, the best VPN with guaranteed zero logs is ExpressVPN. None of your connection times, session information, bandwidth usage, browsing history, IP addresses, or other personal data is stored. ExpressVPN has also undergone an independent audit to prove its no-logs policy is accurate. To ensure total anonymity, you can even create an account with a dummy email address and pay with cryptocurrency.
