Qubes OS tops the list with most Linux users because its primary focus is security, but the most secure Linux distro will vary depending on who you ask — everyone has a favorite. Regardless of which distro you like best, adding a No Logs VPN is a good way to further increase your privacy and security. . PIA’s independently audited No Logs policy guarantees we won’t collect, store, or share your VPN connection data. PIA also protects your traffic with military-grade encryption, rendering your data unreadable if intercepted.
