ExpressVPN and Unblock-Us VPN take very different approaches to securing your internet connection. While ExpressVPN is a traditional VPN that changes your IP address by routing your connection through a secure server, Unblock-Us requires you to change the DNS settings on your device itself and then routes your connection through a proxy server. While this means that Unblock-Us VPN doesn’t affect your connection speed, it also means that you won’t have most of the security features you would expect from a VPN, including a kill switch, AES encryption, and your choice of tunneling protocols. Meanwhile, ExpressVPN offers all those features, as well as exceptional speeds. One apparent advantage of the Unblock-Us approach is that you don’t need to manually switch servers to gain access to regionally specific content. However, there is no guarantee that you will actually be able to create a secure connection and unlock the content you want. With ExpressVPN, you know exactly where you are connecting, that the connection is secure, and that you can access all your favorite streaming services and websites.
