Speed
NordVPN holds a clear edge here. Its NordLynx protocol consistently delivers faster download and upload speeds in third-party testing, especially on long-distance server connections. Surfshark uses WireGuard too and is no slouch, but speed variance across servers is a known weakness — some servers deliver excellent results while others underperform. For 4K streaming or large file transfers, NordVPN is the more consistent choice.
Server Network
NordVPN operates across 111+ countries, giving it a significant advantage over Surfshark's 100 countries and 3,200+ servers. More country coverage means better options for geo-unblocking, lower-latency local connections, and more flexibility when specific servers are under load. Both networks are more than adequate for everyday use, but NordVPN wins on breadth.
Security & Privacy
This is essentially a draw. Both services offer 256-bit encryption, audited no-logs policies, a kill switch, and DNS leak protection. Surfshark adds MultiHop and NoBorders for users in restrictive environments. NordVPN counters with Threat Protection Pro and a longer track record of audit transparency. Neither has suffered a significant data breach that compromised user privacy.
Streaming
NordVPN is widely regarded as one of the best VPNs for streaming in 2026, reliably unblocking Netflix US, BBC iPlayer, Disney+, Hulu, and more. Surfshark also works with most major platforms, but users occasionally report more frequent blocks that require switching servers. If streaming is your primary use case, NordVPN is the safer bet.
Device Limits
This is Surfshark's clearest win. Surfshark allows unlimited simultaneous connections, while NordVPN caps connections depending on the plan tier. For individuals this is rarely a constraint, but for families or teams protecting 10+ devices, Surfshark's policy is a meaningful practical advantage.
