A great article worth your time to read taking into account recent Edwin Snowden comments. The article compares the popular VPN types in use today. The best one? OpenVPN followed closely by IKEv2 (+IPSec). Personally i’d go for IKEv2 if i had a mixed environment (Windows and Macs) and if i expect Apple and Android phones to participate. Otherwise, if you’re just accommodating Windows clients, use OpenVPN. Apple MacOS, IOS and Windows 10 have IKEv2 installed.
