- Surfshark has launched its own custom protocol, Dausos
- Promises to be 30% faster than other VPNs
- Quantum-resistant cryptography further increases security
Surfshark has just introduced its own custom VPN protocol, Dausos.
Surfshark’s new cutting-edge protocol promises to outperform the best VPNs on the market by offering record speeds up to 30% faster than its competitors and a dedicated tunnel for each user.
Currently available to 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 happier.
How does Dausos work?
Unlike protocols like 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 user’s data, it aims to effectively eliminate slowdowns caused by other users, especially at peak times, ensuring a smoother experience while protecting data packets in transit from external interference.
Additionally, the system adapts to network and device conditions, intelligently routing users’ data packets according to their network configuration for best results.
“This ensures optimized performance tailored to the user’s specific network configuration,” explains Surfshark.
The obvious victory? Less overall processing means faster connections, and Surfshark claims its system is now almost a third faster than its rivals.
To make you even happier, Surfshark has also equipped it with many innovative security features.
An integrated root certificate issuance system improves the protection and authentication of user connections through the use of ML-DSA signature scheme. This innovative digital signature algorithm ensures that the sender is genuine and that the data shared remains unaltered, positioning itself at the forefront of the adoption of post-quantum secure certificate schemes.
To further enhance its next-generation capabilities, the protocol has also introduced a hybrid key exchange mechanism (X25519MLKEM768), which combines the established
This follows Surfshark’s January release of post-quantum encryption on WireGuard on macOS, Linux, and Android.
Session Control: Updated
The protocol also improves session control, specifically focusing on increasing key management security. Thanks to the implementation of post-commitment security (PCS)The system protects users’ digital realms by always generating a new key every time a new connection is established.
This ensures that if a key is compromised, hackers cannot intercept further communications or decrypt any future messages generated by that key.
Furthermore, a post-randomization technique It takes security to new levels by establishing different port connections, unlike more traditional systems that connect to a fixed server.
“With Dausos, each session connects via a random port address to a server, like you change your gate every time you fly,” explains Karolis Kaciulis, Lead Systems Engineer at Surfshark.
The protocol was recently audited by Cure53, a Berlin-based cybersecurity consultancy. The company examined the connection architecture and encryption features and concluded that there were no critical or serious vulnerabilities, paving the way for broader adoption.
With the latest release, it seems clear that Surfshak is in the middle 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 100Gbps servers to potentially handle significantly more data capacity than today’s fastest VPNs.
Newly appointed CEO Dovydas Godelis told us a month ago that the VPN’s mission was still to “become the Revolut of cybersecurity.” Looking at the launch of this new cutting-edge protocol, it seems like he wasn’t kidding. Which leaves us wondering: what other surprises could the company have in store?
