Mullvad VPN adds QUIC obfuscation on Android and iOS to bypass firewalls and censorship

Mullvad VPN has introduced QUIC obfuscation for its Android and iOS apps, allowing users to bypass firewalls and censorship in restrictive environments. This new feature aims to improve access for individuals in regions where conventional VPN protocols, such as WireGuard, face blocking.

The QUIC protocol, developed by Google, operates at the transport layer and leverages the User Datagram Protocol (UDP). It reduces latency, delivers faster data transmission, and integrates encryption directly, making it both efficient and resistant to inspection compared to traditional protocols like Transmission Control Protocol (TCP).

With the new update, Mullvad’s QUIC obfuscation tunnels WireGuard traffic to make VPN connections less detectable by network restrictions. To access this functionality, users need to update their Mullvad VPN app to version 2025.8 or later on Android or iOS.

Following the rollout, the app will automatically attempt to use QUIC when repeated connection failures occur. Users can also manually enable QUIC obfuscation in the settings. Mullvad notes that this feature is intended for users facing connectivity issues or operating in restrictive countries, and it does not enhance performance or privacy in other scenarios.
