One of the most important choices you make when selecting VPN hardware or software is which VPN protocol to use. A VPN product might support multiple protocols or only one. A protocol that's weak or not widely supported could render your VPN unusable if someone exploits a vulnerability. A proprietary protocol could mean future compatibility problems.

I strongly recommend that you stay away from products that use proprietary, nonstandard protocols and stick to one of the following major protocols.
