Are all VPNs the same?

There are many personal VPNs available today, from the very expensive to "free." You should be cautious about choosing a free or very cheap VPN. While they may be free or very low cost, you agree to let them look at your data for marketing purposes. Basically, you may be giving them license to look at your personal data. So "free VPN" is really not much of a bargain at all, and certainly not a privacy product.

In addition, some VPN services are built on insecure servers. What makes a VPN secure is knowing that the server you are connecting to is a secure server. And if it 's not, then all the encryption in the world is useless.
