The VPN market has long relied on open-source protocols originally designed for enterprise use. Surfshark has officially introduced Dausos — the first VPN protocol engineered specifically for everyday consumers. Named after a Lithuanian word for "heaven," Dausos represents a new paradigm of digital freedom and security.
Dedicated Tunnels vs. Shared Infrastructure
WireGuard and OpenVPN route multiple users through a shared tunnel. Dausos gives every user a dedicated, isolated data tunnel — eliminating cross-traffic interference and significantly boosting both privacy and performance.
AEGIS-256X2 Encryption
At the core of Dausos is the AEGIS-256X2 encryption algorithm — a first in commercial VPN services. It outperforms AES-GCM on modern hardware:
- Substantially reduced latency during packet processing
- Improved throughput on mobile and desktop devices
- Up to 30% faster than standard protocols
Post-Quantum Security
Dausos uses a hybrid key exchange: X25519 + ML-KEM (NIST standard), protecting against "Harvest Now, Decrypt Later" attacks — where encrypted data is intercepted today to be decrypted by future quantum computers.
Independent Audit and Availability
The protocol architecture was independently audited by Cure53. Currently available in beta on macOS only — Windows, Android, iOS, and Linux support coming soon.
