Privacy and Transparency
Proton VPN is the stronger privacy-transparency fit.
Proton VPN's approved repository emphasizes open-source clients, Swiss jurisdiction, repeated Securitum no-logs audits, transparency reporting, Proton Foundation control, and minimal data retention.
Surfshark has meaningful audit activity, including Deloitte no-logs assurance, Cure53 work, and SecuRing assessment. However, it should be framed as closed source with multiple audits, not open source.
Surfshark's logging language needs more caution: the approved repository says it is best described as a no-activity-logs VPN with limited operational metadata, not as a service that collects nothing.
Free Plan
Proton VPN is the clear free-plan fit.
Proton VPN's repository identifies a permanent free plan with unlimited data and meaningful limits around devices, servers, speed, streaming, and gaming.
Surfshark's repository includes volatile trial terms, but it does not support presenting Surfshark as having a comparable permanent free plan.
Readers who want to start without paying should look more closely at Proton VPN, while still understanding the free tier's limits.
Value, Families, and Many Devices
Surfshark is the stronger household-value fit.
Surfshark's clearest practical advantage is unlimited simultaneous connections, which the approved research treats as especially useful for households, families, and device-heavy users.
Proton VPN's value case is different: it is strongest for readers who care about privacy transparency, open-source clients, audits, and a credible free plan.
Pricing and plan details are volatile for both products. Surfshark's repository specifically warns about promotional pricing, renewal mechanics, and refund exceptions.
Beginner Experience
Surfshark is simpler for mainstream household use; Proton VPN is better for privacy-focused beginners.
Surfshark's repository says ease of use is one of its clearest advantages, and independent sources describe it as simple, beginner-friendly, versatile, and robust for ordinary use.
Proton VPN is also suitable for nontechnical users, but beginners may need more explanation around Secure Core, Swiss legal nuance, free-plan limits, and the difference between privacy protection and full anonymity.
The better beginner choice depends on intent: privacy-first beginners should lean Proton VPN; value and household users should lean Surfshark.
Security Features
Both are strong, with different emphasis.
Proton VPN's approved repository includes WireGuard, OpenVPN, IKEv2, AES-256 or ChaCha20 depending on protocol, leak protection, kill switch controls, Secure Core, DNS-level blocking on paid plans, open-source clients, and port forwarding.
Surfshark's approved repository includes kill switch, split tunneling, obfuscation, MultiHop, NoBorders, CleanWeb, rotating IP, static IP, RAM-only server claims, DNS leak protection, 2FA support, and Nexus-related claims.
Surfshark's Dausos architecture remains an open question around maturity, specification, threat modeling, and follow-up review.
Speed and Performance
Both can be fast enough for ordinary use, but performance evidence is mixed by use case.
Proton VPN's repository says it is generally fast enough for everyday use and HD or 4K streaming, but not always the fastest and not ideal for all latency-sensitive use.
Surfshark's repository reports strong pure throughput evidence, but also flags latency and jitter concerns in some tests.
Neither product should be chosen from headline speed claims alone. Route, server, device, protocol, distance, and test method all matter.
Streaming
Both have positive evidence, and both require current verification.
Proton VPN has positive paid-plan streaming evidence in the approved repository, but streaming compatibility is explicitly marked volatile.
Surfshark is capable for streaming, but the approved research includes mixed independent findings, including disagreement between Tom's Guide and TechRadar.
Do not treat service-specific streaming access as stable for either product.
Torrenting and Gaming
Proton VPN has the clearer advanced P2P edge; neither is ideal for competitive gaming.
Proton VPN's repository says paid plans support P2P on most servers, port forwarding, and no paid-plan data caps according to independent reviewers.
Surfshark is a good casual torrenting choice, but the approved research says it does not support port forwarding.
For gaming, Proton VPN is not positioned primarily as a gaming VPN, while Surfshark is best understood as a budget casual-gaming VPN with latency and jitter concerns in some tests.
Pricing and Plan Uncertainty
Do not decide from stale pricing. Verify current terms for both products.
Proton VPN's repository flags pricing, plan names, device limits, server counts, countries, streaming compatibility, refund details, support availability, and court-order nuance as open or volatile.
Surfshark's repository flags pricing, promotional plan lengths, tiers, renewal prices, refund exceptions, trial terms, device limits, platform support, server counts, countries, streaming outcomes, and Dausos maturity.
Both products require current verification before publication or purchase.
