These two are aimed at the same reader: somebody who wants to cover every device in the house without paying per seat. On that requirement they both deliver. On almost everything underneath it they do not.
Unlimited devices, and which one protects them
Surfshark's kill switch allowed traffic through after a restart under testing. Windscribe's holds. That is the whole first half of this comparison, because a kill switch is the feature whose failure is silent — the exposure happens in the seconds after a reconnection you did not notice, and nothing tells you afterwards.
Surfshark also does not support IPv6, and its guidance is to disable IPv6 on your network rather than have the VPN handle it. Windscribe supports port forwarding, which Surfshark lacks entirely, and streaming, which Surfshark does not claim.
Both offer multi-hop, ad blocking, obfuscation and a fleet running from memory with nothing on disk. Both are quick enough that speed will not decide this, which leaves the protective features to do it.
Where the free plan fits
Windscribe's free tier covers unlimited devices too, and the paid plan can be assembled by location so you buy only the countries you use. Surfshark has no free tier at all.
The renewal follows the same pattern. Windscribe renews at the rate it showed you. Surfshark's advertised rate covers twenty-seven months and then roughly doubles. Windscribe also asks for no email address and no password, and accepts cash.
The one place Surfshark is ahead is evidence of current practice. Deloitte assessed its servers in June 2025, with a separate network test that December. Windscribe's last outside server review was June 2024, past the two-year mark. Both are registered inside intelligence-sharing agreements — the Netherlands in the fourteen-country one, Canada in the five.
Which should you choose?
Choose Windscribe unless the ageing audit is decisive for you. It costs less over time, needs no identity, handles IPv6, offers port forwarding, and its protective features behave as labelled.
Pick Surfshark if a recent server audit outweighs a kill switch that a lab could not get to hold, and you will verify that switch yourself after a reboot before you rely on it.

Unlimited devices at a low rate that does not stay low.
