TunSafe

TunSafe is the first high-performance VPN client that uses the well-established WireGuard protocol, a fast and modern VPN service that uses state-of-the-art cryptography technologies.

The first thing you need to know about TunSafe is the fact that it's free and open-source. It uses a series of well-proven cryptography frameworks such as Curve25519, ChaCha20, Poly1305, BLAKE2, and HKDF.

Another noteworthy aspect is the fact that the app boasts a multi-threaded design that ensures up to 6 times higher throughput (megabits per second) than most OpenVPN-based services. All of this without putting any strain on your computer's resources.

As mentioned before, TunSafe is designed with speed and low resource consumption in mind. It's written in C++ for maximum performance, with works with all types of Internet connections, it allows you to import any number of WireGuard config files, and has a lot of nifty features such as an instant Kill-Switch, LAN-IP bypass, a WG-compatible command-line tool, and support for IPv4 and IPv6.

Because the app allows you to host your own VPN service, getting started with TunScape requires you to undergo a relatively easy configuration procedure.

First thing's first: you'll need an account with a VPN provider of your choice that supports the WireGuard protocol. Once the provider gives you the WireGuard configuration file (ending with the extension ". conf"). Worth noting is the fact that you can also use your free VPN server if you don't have a WireGuard-compatible VPN provider.

During the installation process, you'll be prompted to install the TAP network adapter kernel module. Make sure to confirm the installation since this component is important for the app's functionality as it captures the TCP/IP packets from your computer.

Next, drag the configuration file onto TunSafe's window. Confirm that you want to import the configuration file into the app, and if everything went as planned, you should be able to see a "connection established" message. You can configure the current config file in any text editor (even Notepad).

Taking everything into account, while the whole concept behind TunSafe and WireGuard might seem a bit too abstract for some, it should be said that both are great examples that showcase how the VPN industry evolves. For one, WireGuard is regarded as an improved solution over OpenVPN (for example), and TunSafe is a modern layer 3 VPN tunnel that uses this state-of-the-art protocol to its fullest extent.
