OpenVPN and IPsec offer similar speeds and security, but IPSec is reportedly compromised by the NSA. IPSec is easier to use as most platforms have built-in IPSec clients, so you don’t have to rely on third-party apps. You can pair IPSec with other VPN protocols like IKEv2 and L2TP, but it can also work on its own. That said, OpenVPN is better at getting around firewalls.
