Mullvad VPN

In 2024, Mullvad launched DAITA (Defense Against AI-guided Traffic Analysis), a feature that adds dummy traffic patterns to prevent AI systems from identifying user behavior even on encrypted VPN connections. This addressed emerging threats from machine learning-based traffic analysis that could deanonymize users despite encryption.

In April 2023, Swedish police executed a search warrant at Mullvad VPN's offices in Gothenburg, Sweden. The police attempted to seize computers containing customer data but left without taking any equipment after Mullvad demonstrated that no customer data existed to seize, as the company does not log user activity or even require email addresses for account creation.

In 2023, Mullvad completed migration of all its VPN servers to diskless, RAM-only operation. This means all server data is lost when power is cut, making it physically impossible to recover any user data even if servers are seized. This represented a significant investment in privacy infrastructure beyond what was legally required.

In 2019, Mozilla partnered with Mullvad VPN to power its Mozilla VPN product (initially Firefox Private Network). Mozilla selected Mullvad after evaluating VPN providers for privacy practices, no-logging policies, and transparency. The partnership brought Mullvad's infrastructure to a much wider audience through Mozilla's trusted brand.

Mullvad VPN has maintained fully open-source client applications for all platforms (Windows, macOS, Linux, Android, iOS) and regularly commissions independent security audits, publishing the results publicly. The company was also an early adopter and contributor to the WireGuard VPN protocol.
