Instead of sharing a tunnel with other user traffic, Dausos provides each user with their own tunnel. Initial tests reveal promise, but it isn’t quite there, yet, in terms of performance compared to WireGuard.  Surfshark has unveiled Dausos, a new virtual private network (VPN) protocol designed to improve consumer-grade VPN speeds and security.

Among CNET’s top VPN picks, only ExpressVPN has out-audited Mullvad, with 23 audits commissioned since 2018. Specifically, Assured Security Consultants completed a code audit of GotaTun, Mullvad’s implementation of the WireGuard connection protocol, written in Rust. The audit consisted of a source code review and testing of the entire GotaTun implementation, excluding Mullvad’s AI-traffic analysis blocking DAITA code and its command line interface. Although auditors found no major vulnerabilities in the code, they did flag two security issues of low-risk severity.  The first issue had to do with how GotaTun handled session identifier generation. Auditors noted that GotaTun generated the session identifiers through a 24-bit Linear Feedback Shift Register, …
