Subscribe to our newsletter Surfshark has rolled out its own bespoke protocol, Dausos It promises to be 30% faster than other VPNs Quantum-resistant cryptography further boosts security Surfshark has just unveiled its very own custom VPN protocol,
Dausos.

Surfshark's new cutting-edge protocol promises to beat the best VPNs on the market by offering record-breaking speeds up to 30% faster than its competitors and a dedicated tunnel for each user. Currently available for macOS users and coming soon to other platforms, the protocol whose name
means paradise in Lithuanian also comes loaded with new post-quantum encryption designed to make your digital life even more blissful. You may

up to one of its two-year plans. For the equivalent of $1.78 per month for 28 months of protection, Surfshark Starter is definitely the cheapest plan. Yet, for a little bit more than $2 a month , we think the Surfshark One is a way better deal.

You have time until April 19th to claim the offer. View Deal How does Dausos work? Unlike protocols such as WireGuard and OpenVPN , which route all user traffic through a single digital tunnel, Dausos' system provides each user with their own private, exclusive data channel.

By isolating each users data, it aims to effectively eliminate slowdowns caused by other users particularly at peak times ensuring a smoother experience while protecting travelling data packets from external interference.

Additionally, the system adapts to network and device conditions, intelligently routing users' data packets according to their network configuration for better results.

"This ensures optimised performance tailored to the users specific network configuration," Surfshark explains.

The obvious victory? Less overall processing translates into speedier connections, with Surfshark claiming its system is now nearly a third faster than its rivals. (Image credit: Surfshark) To make it even more bliss-filled, Surfshark has also packed it with many innovative security features.

A built-in root certificate issuance system enhances the protection and authentication of users' connections by using the ML-DSA signature scheme . This innovative digital signature algorithm ensures the sender is genuine and data shared remains unaltered, positioning itself at the forefront in the adoption of post-quantum secure certificate schemes.

To further ramp up its next-gen capabilities, the protocol has also
introduced a hybrid key exchange mechanism (X25519MLKEM768), which combines the established X25519 cryptographic system with a more recent NIST-approved quantum-safe algorithm , ML-KEM, improving protection of user data against both current and future quantum attacks.

This follows Surfshark's January rollout of post-quantum encryption into WireGuard across macOS, Linux, and Android. Session control: upgraded The protocol also enhances session control, specifically focusing on boosting key management security. Thanks to the implementation of post-compromise security (PCS) , the system protects users' digital realms by always generating a new key every time a new connection is established.

This ensures that, should a key be compromised, hackers cannot intercept further communications or decrypt any future messages generated by that key.

Furthermore, a post-randomisation technique brings security to new heights by establishing varying port connections, unlike more traditional systems that instead connect to a fixed server.

"With Dausos, every session is connected via a randomised port address to a server, like changing your gate every time you fly," explains Karolis Kaciulis, Leading System Engineer at Surfshark.

The protocol was recently audited by Cure53, a Berlin-based cybersecurity consultancy. The firm examined the connection architecture and encryption features, concluding that there were no critical or serious vulnerabilities, thereby paving the way for its wider adoption.

With the latest release, it seems clear that Surfshak is in the midst of a major development phase and intends to continue improving its product in
terms of overall performance, having recently upgraded its network with industry-first 100 Gbps servers to potentially handle significantly more data capacity than todays fastest VPNs .

Recently appointed CEO Dovydas Godelis told us a month ago that the VPNs mission remained to become the Revolut of cybersecurity . Looking at the rollout of this new cutting-edge protocol, it seems he wasnt kidding. Which leaves us wondering: what further surprises might the company have in store?
