What to check before using a public VPN
Public OpenVPN servers are useful for testing routes, ports, countries and client setup, but they should be reviewed before real use. Look for a recent check time, measured speed, acceptable latency, clear protocol and port data, and a country that matches your goal.
After downloading a profile, inspect the .ovpn file, connect with a trusted OpenVPN client, confirm that your public IP changed, and run a DNS leak check. Avoid sensitive accounts on unknown third-party endpoints unless you understand and trust the operator.
