Surfshark has announced Dausos, a proprietary VPN protocol that uses AEGIS-256X2 encryption and provides per-user dedicated tunnels to improve security and performance; Surfshark cites up to 30% speed improvements versus other protocols, engaged Cure53 for an audit with no critical/high findings for the protocol itself, addressed early residential performance issues, and currently offers Dausos in beta on macOS with broader platform rollouts planned.
