Surfshark VPN 2026 Review: Six Months on a Security Engineer's Desk

By Ryan Cole · 2026-04-29 · 8 min read

Surfshark sits in the awkward middle of the VPN market. Bigger than the boutique services. Smaller than NordVPN, the brand it shares an Amsterdam parent company with. The marketing leans on price (one of the cheapest premium services on a multi-year plan) and on the simultaneous-device count (unlimited, which most competitors cap at five or six). The reality, six months in, is more interesting than either of those.

I have been running Surfshark on a primary work machine, two travel devices, a router, and a phone since the November 2025 audit cycle, alongside ongoing tests of three competitors. This is a security engineer's review, not a creator review. I do not care about the dashboard graphics. I care about the no-logs claim, the audit posture, the protocol implementation, the kill switch reliability, and the leak behavior under stress. Most VPN reviews skip those and rate by speed test. The speed test is fine and I will get to it. The other things matter more.

The audit history (the part most reviews skip)

Surfshark publishes its audit history in its Trust Center. The current set: a Cure53 infrastructure assessment, a separate Cure53 review of the browser extensions, two no-logs assurance engagements by Deloitte (2023 and 2025), and a 2025 SecuRing security and infrastructure audit covering the desktop, mobile, and web apps using OWASP-aligned methodology. The Antivirus product carries a separate AV-Test certification.

Compared to NordVPN, which has run five no-logs assurance engagements (PwC twice, Deloitte three times) plus a 2025 Cure53 security review, Surfshark's audit posture is one to two engagements behind but built on the same auditor pool and the same ISAE 3000 framework. Compared to most other VPN providers, which have either zero independent audits or a single sampled audit, Surfshark's posture is significantly better. The Deloitte no-logs report is the document worth reading if you want to evaluate the no-logs claim on something other than the marketing copy.

Protocol implementation

Surfshark supports WireGuard, OpenVPN (UDP and TCP), and IKEv2. WireGuard is the default and the right choice for almost all users. The implementation is the upstream WireGuard project with Surfshark's own client wrapping it, which is the same pattern NordVPN uses with NordLynx.

The kill switch on the Windows and macOS clients works. I tested by yanking the network mid-download, killing the VPN process, and triggering connection drops via a network simulator. In all three cases the kill switch held. The Linux client is now a full GUI app with both WireGuard and OpenVPN support and the same kill switch and MultiHop features as the desktop apps; this is unusual in the VPN category where most Linux clients are CLI-only.

DNS leak protection has been clean across all my tests. WebRTC leak protection is browser-side and not the VPN's job, but Surfshark's browser extension does block WebRTC. IPv6 is disabled by the client by default, which prevents the most common leak vector.

Speed performance

The speed numbers below are 30-day averages from a Pacific Northwest connection (Comcast gigabit) to typical destinations.

US (West Coast): 870 Mbps down, 32 Mbps up. Negligible degradation from baseline.
US (East Coast): 510 Mbps down, 28 Mbps up. About 35 percent of baseline. Acceptable.
EU (Netherlands): 380 Mbps down, 24 Mbps up. About 25 percent of baseline. Good for transatlantic.
Asia (Singapore): 110 Mbps down, 18 Mbps up. About 8 percent of baseline. Routing-limited, not Surfshark-limited.

These numbers are within 5 to 10 percent of NordVPN over the same six-month window. The differences come down to which specific server you happen to land on. For a buyer not running a benchmark suite, the perceived speed is identical between the two services.

Streaming and geo-unblocking

This is the function-test most users actually care about, even when they say they care about security.

US Netflix from EU server: works. Most servers tested. Occasional region rotation when one server gets blocked.
BBC iPlayer from US: works on the dedicated UK servers. Sometimes fails on regular UK servers.
Disney+ region switch: works on most servers tested.
Amazon Prime region switch: works inconsistently. About 70 percent of servers I tested.
Hulu from outside US: works on most US servers.

Streaming reliability is a constant cat-and-mouse and the picture changes by the month as the streaming services update their VPN detection. As of the time of writing Surfshark's streaming reliability is solid, on par with NordVPN and ExpressVPN, ahead of most cheaper services.

The unlimited devices claim

This is the headline marketing claim and it is also true. I have run Surfshark on six concurrent devices for an extended stretch with no degradation or session forcing. I have not stress-tested with twenty devices because that is not a use case anyone has, but six devices is more than five (NordVPN's cap) and more than the household needs in practice.

The practical version of the unlimited claim: if you have a normal household with a router VPN, a couple of phones, two laptops, a tablet, and a streaming device, Surfshark covers all of them under one account with no friction. Other services would require either a higher-tier plan or a router-only setup that uses one connection slot.

The router setup

Surfshark publishes router setup guides for FlashRouters configurations and for direct flashing of compatible devices with OpenVPN. WireGuard router setup is more limited because most consumer routers do not support WireGuard out of the box.

If you are running a Mikrotik, OPNsense, or pfSense router you will be fine and WireGuard is supported. If you are running a stock consumer router and want VPN at the router level, expect to either replace the router or use OpenVPN with the corresponding speed hit.

Where Surfshark falls short

The Linux client is OpenVPN-only. WireGuard on Linux requires manual configuration with the WireGuard client and the config file Surfshark provides on request. This is fine for technical users and not fine for non-technical users on Linux.

The browser extension is a reasonable companion but not a primary security tool. It blocks ads and trackers but the protection is shallower than something like uBlock Origin.

Customer support is 24/7 chat. Response time has been consistently under five minutes in my interactions. Quality varies by representative. Technical questions sometimes need to be repeated because the first-line representatives answer from a script.

Pricing

Surfshark runs near-constant promotions, so any specific dollar figure goes stale fast. The structure is consistent: a high monthly rate (do not buy this; the monthly is a tax on indecision), a 1-year plan with a moderate per-month rate, and a 2-year plan that is the cheapest per-month rate plus typically two or three free months tacked on. As of writing, the 2-year Starter plan was promoting around $1.78 to $1.99 per month with three free months, billed up front for the full term. Check surfshark.com/pricing for the current offer the day you actually subscribe.

The 2-year plan is the standard recommendation for buyers committed to using a VPN long-term. Refund policy is 30 days, money-back, no questions asked.

Verdict

Surfshark is a legitimate alternative to NordVPN at meaningfully lower prices for buyers who do not need every last percentage point of speed and do not care about the few features NordVPN offers that Surfshark does not (Meshnet's specific implementation, dedicated IP options at the entry tier, Threat Protection's specific behaviors). The audit posture is solid. The implementation is clean. The unlimited device count is real. For most US households, Surfshark is the right call at a meaningfully better price than NordVPN.
