Guide outlines methods to test VPN encryption and security features

A recent guide outlines methods to test a VPN's encryption, emphasizing the importance of strong privacy controls. Users can check their IP address using command-line tools and compare it with online services to identify potential weaknesses. Wireshark, a free application, can detect data leaks by monitoring outgoing data streams. The guide highlights that even reputable VPNs may have vulnerabilities, such as ARP poisoning, which can expose users' true IP addresses. BrowserLeaks offers user-friendly tools for testing various aspects of VPN security, including IP and DNS leaks. The guide recommends running multiple tests to ensure comprehensive protection and to monitor for any ISP interference with the VPN connection.
