Yes, there are several ways to find out if someone is using a virtual private network. For example, you can check the IP address of the computer or mobile device they are using. You can also try looking up their internet service provider and seeing if it has any information about them using a VPN. Additionally, many VPN services offer an online status page that will show whether or not the user is currently connected.
