- Mullvad has added Quic’s obfuscation for Wireguard in its desktop applications
- The protocol allows users to combine with regular traffic to avoid censorship
- A growing number of VPN now offers tools against censorship
Mullvad has implemented Quic’s obfuscation for Wireguard, with the aim of making VPN traffic more difficult to detect and block by sophisticated firewalls.
Designed with users in very censored regions in mind, this latest update disguises Wireguard traffic as ordinary web traffic, providing a more reliable connection in countries such as China and Russia, which are accelerated to a large extent or block regular Wireguard traffic.
How quic works and why it matters
Quic, abbreviation for rapid UDP Internet connections, is a fast and light transport protocol built in UDP. Google originally designed it as a faster and faster replacement for HTTP/2. It now serves as the basis for the HTTP/3 emerging standard.
Basic Quic forces: low latency, incorporated multiplexation (which means that it can transport multiple data threads simultaneously) and resistance to Package loss: Everyone makes it an attractive carrier for virtual private network traffic (VPN). Quic mullvad obfuscation encapsulates the usual Wireguard UDP packages within Quic, the same transport protocol used by the tastes of Google Services and YouTube.
To make this work, Mullvad uses the Masque standard, that Tuna Wireguard UDP traffic through an HTTP/3 connection. In simple terms, this makes the packages look like normal encryption traffic so that firewalls and censorship systems have more difficulties in identifying and blocking them.
We are excited to add Quic’s obfuscation for Wireguard, aimed at helping users avoid firewalls and censorship. This new feature is now available on all desktop platforms. Android and iOS applications will include quic obfuscation in future versions. Read more here: …September 9, 2025
The new feature, now available through the Windows and Mac VPN applications in Mullvad (version 2025.9 hereinafter), it looks glable within the configuration.
However, users who experience multiple failed connection attempts will automatically return to Quic according to the default settings of the application.
If it is a Mullvad subscriber, all you need Settings > VPN configuration > Sireguard configuration > Obfuscation > Appointment.
Mobile users should not feel excluded either. Mullvad has already confirmed that their Android and iOS applications will also receive the quic obfuscation in future updates.
How to compare Mullvad’s Quic against other important VPNs
A growing VPN number is implementing ways for users to avoid censorship and other network restrictions. A lot The best VPN suppliers, including Mullvad, constantly seek newer and more effective methods, is only their approaches differ.
Both Proton VPN and NordvPN have developed patented protocols to combat censorship. The stealthy protocol of Proton wraps wire control within TLS to imitate HTTPS, while Nordvpn has recently introduced its own censorship resistant protocol, Nordwhisper.
Expressvpn, Surfshark and Mullvad, on the other hand, depend on existing technologies and adaptations for their VPN obfuscation tactics. ExpressvPN automatically applies the OpenVPN traffic obfuscation on its network. Surfshark uses camouflage mode to stir OpenVPN packages.
Both patented protocols and the standard emerging transport of the industry and quic have their merits. While censorship continue to avoid a free and open Internet, VPN suppliers such as Mullvad will continue to find new ways of helping users to slide restrictions beyond.
