Introducing WireGuard VPN

Introducing WireGuard VPN

In February 2019, Astrill became one of the very few virtual private network (VPN) providers to offer WireGuard as part of its services. It is aimed at providing fast connection, tighter security, and enhanced encryption with a much simpler architecture compared to IPSec and OpenVPN. Because the protocol makes use of cryptography and is easier to set up and manage, it is touted as one of the most secure tunneling protocols in virtual privacy technology.

WireGuard – Fast, Modern, and Secure VPN Tunnel

This release reflects Astrill’s superior security expertise and aligns with our mission to provide continuous support for the advanced and diverse needs of our users.

Here’s some more critical information to understand why WireGuard VPN is a much safer bet for a variety of applications.

What is WireGuard VPN?

WireGuard is a simple tunneling protocol that is used to implement VPN techniques across various configurations. It is relatively faster, efficient, and secure than existing protocols adopted by common VPN providers. Its smaller size and simple architecture enjoy support from developers owing to the ease in peer review and auditing. The small codebase (1% of that of OpenVPN) further ensures better prevention from security attacks.

A free and open source software application, WireGuard is promoted as an experimental code by its developers. It is for this reason why Astrill recommends its usage for non-critical applications.

The protocol offers impeccable speed and encryption due to its dependence on some of the leading technologies in the data security industry. It utilizes ChaCha20 for encryption, Poly1305 for data authentication, and Curve25519 for key exchange, all of which have been ‘a result of a lengthy and thoroughly considered academic process.’

Salient Features of the Open-Source Protocol

Apart from its strong research-based origin, there is plenty more that WireGuard can achieve as a standard protocol. Here’s a list of some of its most salient features and how they will help you enjoy a better VPN experience.

  • High speed and latency owing to minimal architecture; this is one of the biggest factors for users while choosing a VPN
  • Smaller attack surface that other protocols; this means less vulnerability from hackers and phishers
  • A smaller codebase also means easier development and redevelopment
  • Usage of state-of-the-art cryptographic cipher suite for encryption
  • Added facility for roaming between Wi-Fi and 4G connections.

Besides, the highlight of Astrill’s support for WireGuard is that we have automated the process of key generation and execution which is an important part of its overall implementation. Typically, users of a VPN provider that offers this advanced protocol have to manually generate keys and upload them to the servers. This is partly because the protocol is still at a nascent stage of development. This is also one of the reasons why we do not recommend using it for applications where security is critical. But experimenting with its latency and trying out different applications to match your needs is something you can do readily with our native clients.

How to Switch ON WireGuard VPN on Astrill?

If you are an Astrill user, setting up your application client will just take a few seconds. Run the application on your preferred device and select WireGuard VPN. Ensure that you are connected by toggling the ON/OFF switch. And you are ready to experience what is touted as the future of VPN technology.

If you are running an old version of Astrill, you may need to update it. If you face any difficulties, get in touch with our support team.


WireGuard VPN is available on Astrill along with our other strong OpenWeb and StealthVPN protocols. As of 22 February 2019, it is compatible with Windows, macOS, and Linux operating systems. Check out our website for more information on this release.
