Head to head
The gap
The security score is not a total of good things. It starts at 100 and eight channels each take a share of what is left, so one channel can settle a record on its own. Both records are drawn here on the same scale — the model’s own cap of 0.9 — rather than on a scale fitted to this pair, which would make every comparison look equally dramatic.
Line by line
Every field the contract publishes about a provider, in the contract’s own groups, including the rows where the two agree — a table that printed only differences would invent a disagreement, and one that printed only the interesting rows would be us choosing what is interesting. Open a group to read its rows; each one says how many it holds and how many of them the two records answer differently.
A green cell means the methodology itself prices that value below the other one, not that we prefer it. Rows the model does not price carry no mark at all: price is never marked, because nothing in the model says cheaper is safer, and neither is coverage, platform count or devices. Where a value was never established the cell says so instead of showing a zero.
What actually happened
Other pairs
Pairs within the top ten get a page — 80 comparisons in all. Records below that are not paired here: a comparison earns a page where the choice between the two is a real one, and that choice is made near the top of the register.

Open questions
Still open on this record.
What the audit actually checked. The no-logs finding is strong and narrow at once. Securitum inspected production servers in person in August 2025 and has done so annually since 2022.
The limits the report states itself. It is a point-in-time check, a guided review of systems demonstrated by Proton's engineers rather than an unsupervised forensic examination, and a representative sample rather than the whole fleet. CI/CD, source code and the account-management systems were explicitly out of scope, so nothing here speaks to what the billing side holds.
The appeal, and what it does not settle. The 22 October 2021 appeal is cited here with a caveat worth stating plainly: the Federal Administrative Court ruled that email services are not telecommunications providers, and neither the judgment coverage nor Proton's own account of it mentions the VPN.
What actually settles the two fields. What settles C10 and C11 is that Switzerland carries no mandate basis in the catalogue's own country list; the appeal corroborates how Swiss authorities treat Proton and is not by itself a finding about Proton VPN. A ruling on a sibling service is thinner ground than the citation makes it look.
The single largest open item. Proton offers exit locations in eight countries that impose a logging mandate. Whether hardware actually sits in any of them is not established: Proton withdrew physical servers from India in 2022 and documents Smart Routing for locations it serves from elsewhere, which points to virtual, but that was verified for India alone. Establishing C09b_mandate_hosting is the single largest open item on this record.
Still open on this record.
The two prices. U04_price_monthly=16.45 and U04b_price_yearly=79.00 are the Surfshark Starter (VPN + Alternative ID) renewal figures in USD. The pricing page itself only ever shows the promotional first-term rate, but the ToS links a current-recurring-amounts page (surfshark.com/terms-of-service/pricing) that lists renewal prices by term — read there on a US IP, since currency is geo-locked. There is no VPN-only tier below Starter.
What no primary document confirmed. C00_architecture, C08_servers_ownership, U09, U11, V12/V13, X04, X06-X08, X10, X11 were not confirmed against a primary document in the time available and are left unknown. M11_owner_jurisdiction and X04_owner_group_history carry the same gap recorded for nordvpn.json: Nord Security's own jurisdiction and record are not stated on either brand's site.
India, and the secret-order regime. P04_mandate_response=withdrew_physical is the June 2022 India exit, restored from Surfshark's own blog (surfshark.com/blog/surfshark-servers-certin-india) after the earlier run found the /trust-center page no longer carried it. P11=judicial_only rests on the transparency report showing the April 2026 Amsterdam District Court warrant and its National-Security-letter and gag-order counters at zero.
Two reports found, maybe not all. Only two Deloitte no-logs reports (Dec 2022, Jun 2025) were found published; there may be others not linked from robots.txt that this audit did not search for by other means.

Notes
On the record as a whole.
The 2021 Swiss order that compelled prospective logging targeted Proton Mail, not the VPN, and is deliberately absent from P12: charging the VPN for a sibling product's order would be a fact about Proton AG, not about this service.
U08 is all_platforms because the support document gives enabling steps for Windows, macOS, Linux (GUI and CLI), Android and iOS/iPadOS — every platform with an app. The same document states two limitations that the value cannot carry and this note can: on macOS the real IP may be exposed briefly while switching servers, and on iOS some Apple service DNS requests can bypass the tunnel with the kill switch on.
U04b_price_yearly records the first-term charge on the 1-year VPN Plus plan: $53.88 for the first 12 months ($4.49/month), stated on the pricing page beside its own renewal line — "then renews at $83.88 every 12 months" ($6.99/month) — which is not the field's value.
On the record as a whole.
surfshark.com is not Cloudflare-walled the way nordvpn.com is: robots.txt, static pages and even the two ISAE 3000 no-logs assurance report PDFs and the December 2025 SecuRing infrastructure pentest report are all fetchable directly, and robots.txt's own Disallow list named the exact PDF paths (evidently meant to keep them out of search results, not to hide them from a direct link).
Both audit PDFs were opened and read in full (level A). The 2025 report's appendix and the privacy policy describe the same record in the same terms: 'user ID and/or your IP address and connection to VPN server time stamps', automatically deleted within 15 minutes of the session ending.
This record was previously read twice — connection_timestamps in V11 from the audit wording, source_ip in C01 from the policy wording — and graded at the worse of the two, which made the fifteen-minute buffer cost more than saying nothing at all: a blank on C01 is the market prior 0.550 and source_ip is 0.750.
R29 now draws the line: state deleted within a declared window tied to the end of the session is the connection, not a record of it, so both fields read connection_timestamps on the same sentence. What is still charged is what outlives the session — the last login date in policy section 2.3.1 and the connection timestamps the auditor names.
Surfshark and NordVPN share a parent (Nord Security, since 2022) but Surfshark's own about-us page states the brands merged 'while operating independently' with separate infrastructure — M18 is set to separate on that basis, mirroring the nordvpn.com record.
U12a is partial rather than yes on the server table's own P2P column: 88 of the 100 listed countries carry it and twelve do not (AU, CL, CO, HR, GR, IE, JP, MX, NZ, TW, TR, AE). The column is drawn client-side, so it was read off the rendered table rather than the static HTML, where every row carries every label.
The transparency report at /transparency-report — which is where /warrant-canary now redirects — carries the April-June 2026 quarter as a table: 374,719 DMCA notices, 33 inquiries from government institutions, 1 warrant, 0 national security letters and 0 gag orders. P08 counts the 34 legal requests and leaves the DMCA notices out: those are copyright complaints about traffic, not requests for a user's data.
The same page states Surfshark is retiring its warrant canary in favour of quarterly reporting, which is why P07 is removed rather than none — the canary existed and was withdrawn deliberately.
U07_protocols carries proprietary for Dausos on Surfshark's own word — its protocol page calls Dausos "Surfshark's proprietary protocol" and publishes no source for it — and that single value is what sets C13_weakest_protocol and the hygiene charge that follows. IKEv2 is kept because Surfshark still documents it, though its own blog records the removal from the Windows app; Shadowsocks is gone from the support index and is not listed.

Proton VPN and Surfshark were assessed by the HushFleet team: Proton VPN scores 70/100 for security, in the Acceptable band, and Surfshark 16/100, in the Insufficient band. They share an independent audit. The 54-point gap opens widest on Integrity — “Has it been caught saying one thing and doing another?” — taking 0% from Proton VPN and 35% from Surfshark.
