AirVPN and StrongVPN are two popular VPN providers with very different key offerings. While StrongVPN offers around 650 servers in 26 countries, AirVPN has only about 220 servers in 20 countries. AirVPN also has only a 3-day money-back guarantee, compared to StrongVPN’s 30-day guarantee for new orders. While both VPNs support the OpenVPN encryption protocol, only StrongVPN also provides support for the L2TP, SSTP, IPSec, and IKEv2 protocols. In terms of dedicated apps, both VPNs have apps for MacOS and Windows, but you’ll only find iOS and Android apps with StrongVPN. If you ever encounter any challenges with either of these VPNs, AirVPN handles inquiries via email and web forms, whereas StrongVPN offers a 24/7 live chat system. These two VPNs have a few things in common, however. They both use 256-bit encryption across their networks and offer protection from leaks and tracking. AirVPN and StrongVPN are also pretty reliable for bypassing tough geo-restrictions from media platforms like US Netflix and Hulu.
