Surfshark Review Focuses on Dausos Protocol, Unlimited Connections and Deloitte Audits

Surfshark review examines the service's WireGuard and proprietary Dausos protocols, its policy of unlimited device connections, and the results of audits performed through 2026. The VPN operates from the Netherlands with a stated focus on RAM-only servers and minimal data retention. Users seeking concrete details on speeds, costs and privacy controls will find the following sections useful.

Surfshark Protocols and Server Network Performance

Surfshark supports WireGuard as the default protocol with added post-quantum features, alongside OpenVPN in UDP and TCP modes and IKEv2. In April 2026 the company introduced its Dausos protocol, which assigns dedicated per-user tunnels and applies AEGIS-256X2 encryption. Cure53 completed an audit of Dausos and related infrastructure in 2026 and reported no critical or high-severity issues within the protocol scope.

The network comprises more than 4,500 servers across 100 countries, with city-level location options and support for static IP and MultiHop configurations. Independent speed aggregates recorded in October 2026 showed average WireGuard downloads above 1,400 Mbps and uploads above 900 Mbps on tested routes, with peaks exceeding 2,900 Mbps. Limited tests indicated Dausos delivered roughly 5.8 percent higher throughput than standard WireGuard after initial fixes. Actual results continue to depend on server load, distance and local network conditions.

Additional tools include a kill switch, CleanWeb ad and malware blocker, split tunneling via Bypasser, and Dynamic MultiHop routing. All paid plans allow unlimited simultaneous connections, with each device maintaining separate encrypted channels.

Surfshark Pricing and Privacy Policy Details

Current promotional pricing lists the Starter and One plans at approximately $2.49 per month or €2.49 per month for the first 27 months when paid upfront, equaling roughly $67.23 for the initial period. The higher One+ tier starts near $4.49 per month equivalent. Renewals occur at standard rates that are not always displayed until checkout. A 30-day money-back guarantee applies, and no free plan exists.

Deloitte issued ISAE 3000 assurance reports in 2023 and June 2025 that confirmed alignment with the published no-logs policy. The policy states that browsing history, IP addresses, session data and bandwidth logs are not retained, while minimal connection metadata is deleted within about 15 minutes. Servers run on RAM-only hardware that clears data on reboot. Quarterly transparency reports have shown zero relevant data requests fulfilled in recent periods. The Netherlands jurisdiction imposes no mandatory retention for this category of data.

Surfshark was founded in 2018 and has operated under the Nord Security umbrella since 2022 while retaining separate branding and infrastructure. Additional security reviews by Cure53 in 2018, 2021 and 2026, plus a SecuRing assessment in 2025, examined code and infrastructure components.

Surfshark Limitations Compared to Alternatives

Surfshark maintains a growing server count and competitive speed figures, yet renewal prices rise substantially after the initial term. Some external audit findings outside the main protocol scope were noted in the 2026 Cure53 report. Independent test conditions vary, so published speed numbers represent aggregates rather than guaranteed performance for every user.

Compared with ExpressVPN, Surfshark provides unlimited connections at a lower entry price while ExpressVPN limits users to eight devices and charges higher rates. Against NordVPN, Surfshark offers a newer proprietary protocol option and lower promotional pricing, whereas NordVPN provides a larger server fleet and more mature feature set in certain regions. Both competitors publish their own audit histories.

Common user reports mention occasional connection drops on distant servers and slower support response during peak promotional periods. No widespread complaints about data logging have surfaced in public forums following the Deloitte reports. The service continues to expand its network and refine Dausos, though users should check the latest audit documents on the official site before committing to multi-year terms.
