If you have ever tried to fire up one of the best VPN apps on a school or office connection only to watch it hang, this is the kind of fix you have
been waiting for. The problem comes down to how tightly some networks are managed. Academic institutions and corporate environments tend to run strict firewall configurations that can block or interfere with VPN traffic, and previously, some Surfshark users hit exactly that wall when connected to the Dausos protocol.

The update is the latest in a string of refinements to a protocol that is still finding its feet, having already been patched once after a TechRadar investigation flagged problems on residential broadband lines. What the
update changes and who benefits The goal of the update is to make sure Dausos connects reliably on restricted networks, such as those you find in academic institutions and corporate environments. You may like Meet Dausos,

"We want as many people as possible to experience the power of Dausos, which is why continuous improvement is our priority," says Karolis Kaciulis,
Leading System Engineer at Surfshark.

Kaciulis explains that, responding directly to user feedback, the update

Whether they are students trying to reach content on campus Wi-Fi or employees working through a
tightly managed corporate connection, this update directly addresses one of the biggest friction points Dausos users have been running into.

Surfshark's reasoning is that a protocol built for ordinary people has to
work in the places ordinary people actually connect from. Today's best Surfshark deals +3 months free Surfshark 24 Months 1.49 /mth View at

from older shared-tunnel technology. What to read next Surfshark VPN review 2026 a fully-featured, low cost privacy solution Amnezia VPN drops new AmneziaWG 2.0 protocol as censorship tactics grow smarter Mullvad VPNs new desktop build prioritizes speed, stability over interface changes

The headline difference is how it handles traffic. Where protocols such as WireGuard and OpenVPN route every user through a single shared tunnel, Dausos gives each connection its own private, dedicated data channel.

By isolating each user's data, it aims to cut out the slowdowns caused by other people sharing the same server, particularly at peak times, and Surfshark claims the protocol can be up to 30% faster than rivals.

For security, Dausos uses AEGIS-256X2 encryption optimized for modern
hardware and is built with post-quantum protection in mind, combining a
hybrid ML-KEM and X25519 key exchange with an ML-DSA self-signed root certificate system so connections stay safe against both current and future quantum threats.

The protocol also leans on post-compromise security, which generates a new
key for every connection so a leaked key cannot expose future sessions, and port randomization that obscures the connection path. It has also been independently audited by the cybersecurity firm Cure53.

To switch it on, open the Surfshark app , head to Settings , VPN Settings , open the Protocol menu, choose Dausos , and connect to a server .
