Surfshark Launches Dausos VPN Protocol Claiming Up to 30% Speed Gains Over WireGuard
What Happened – Surfshark introduced a proprietary VPN protocol called Dausos, built on AEGIS‑256X2 encryption and dedicated per‑user tunnels. Independent testing shows it can approach WireGuard’s performance but still lags behind in raw speed.
Why It Matters for TPRM –
- New cryptographic primitives (AEGIS‑256X2) may affect compliance assessments and future‑proofing against quantum threats.
- Dedicated tunnels reduce cross‑tenant traffic leakage, a risk vector for SaaS and cloud‑hosted services.
- Early‑stage performance gaps could impact business continuity for organizations that rely on high‑throughput VPNs for remote work.
Who Is Affected – Cloud‑based SaaS providers, remote‑work dependent enterprises, and any third‑party that integrates Surfshark VPN for secure connectivity (e.g., MSPs, MSSPs, and enterprise IT departments).
Recommended Actions –
- Review existing VPN contracts and evaluate whether Dausos meets your security and performance requirements.
- Request the Cure53 audit report to verify the absence of critical findings.
- Conduct a pilot test of Dausos in your environment before full deployment.
Technical Notes – Dausos replaces AES‑GCM with AEGIS‑256X2, offers per‑user dedicated tunnels, and claims up to 30 % faster speeds than WireGuard. Cure53 performed an independent assessment and reported no Critical or High findings. No CVEs are associated with the protocol at this time. Source: ZDNet Security
