VPN identification use encryption to scramble personal information into a complex code that can only be read by possessors of a secret key. Those keys are provided by your device and the VPN server, making it extremely difficult for anyone else to spy on your internet activity. Detecting VPN use is possible, however, and can give useful data in the fight against fraud.

VPN identification can be done with tools like Glasswire and Wireshark, which are available for free from a variety of sources. These free tools will look for traffic with an encrypted tunnel, indicating the use of a VPN. These can be used by individuals, corporate networks and even government agencies to test any network for the presence of a VPN.

Cracking the Code: Methods for VPN Identification and Tracking

Another method for detecting VPN use is to look at a person’s IP address. This can be done by searching “what is my IP” on Google or using an online tool. If the person’s virtual IP address matches the VPN provider they are connected to, it can be determined that they are using a VPN.

Lastly, some networks block VPNs by scanning for specific ports that are usually associated with file-sharing programs, such as torrenting software or Usenet programs. This type of port blocking can be a good way to prevent VPN use in countries with strict censorship rules. To avoid this, a person can switch to a different protocol or use obfuscation, which conceals the VPN connection within other protocols and scrambles metadata to make it harder to identify as VPN.
