VPN Independent Audits in 2026: Which Claims Hold Up

Built from the public record, not marketing copy

This piece is built from providers' own published audit and trust-center pages, the auditing firms' report summaries, and named third-party reporting on those reports — not first-hand impressions. Every firm, scope and date below is checked against the provider's own audit page or the auditor's own listing as of September 2026. Where the public record is vague or the sources contradict each other, that gap is stated rather than smoothed over.

What "audited" actually means

"Independently audited" is a phrase VPN marketing pages lean on hard, and it hides two very different kinds of work.

An attestation engagement — the Deloitte, KPMG and Securitum reports below — is what accountants call an ISAE 3000 assurance engagement. Auditors interview staff, inspect server configuration, and check whether the systems described to them match the no-logging claims in the privacy policy, all as of a specific date. It answers one question: did this provider's infrastructure look the way it says it does, on the days the auditor was watching?

A penetration test, the kind Cure53, SecuRing, NCC Group and similar firms perform, is a different exercise entirely. Testers try to break a defined target — an app, a browser extension, a protocol implementation — and report what they found. It answers: does this specific piece of software have exploitable holes right now?

Neither is a permanent guarantee. An attestation covers a point in time; a pentest covers a defined target at a defined moment. A firm can conclude a provider's no-logs architecture looked correct in June 2025 and have nothing at all to say about a code change pushed in March 2026. That is not a flaw in the audit process — it is simply what the document in front of you does and doesn't cover, and this site will not print a bare "independently audited" claim without naming the firm, the scope, and the date, because that phrase alone tells a reader nothing verifiable.

The freshness rule

Audits decay. A 2022 attestation says close to nothing about a company's 2026 operations, especially after acquisitions, infrastructure migrations or leadership changes. This site flags every audit against today's date (September 2026) using one rule:

• Fresh — completed within the last 12 months
• Aging — 12 to 24 months old
• Stale — more than 24 months old

An aging or stale flag isn't a strike against a provider that has simply not re-run the process yet; it's a note that the evidence on file is older, and older evidence tells you less about current operations.

Mullvad is a deliberate gap in this table: it has not published a Deloitte/KPMG-style no-logs assurance engagement, largely because its account-free, no-email-required signup model gives it structurally less to attest to. That's a different kind of evidence, addressed below.

Security and infrastructure pentests: the matrix

Where the public record disagrees

Aggregator blogs and even providers' own press cycles don't always line up cleanly, and this site would rather flag the gap than paper over it:

• ExpressVPN's KPMG date. The assessment's point-in-time coverage is stated as "effective February 28, 2025," but the report itself wasn't published until June 2025. Both dates appear in ExpressVPN's own materials; this piece uses the later, published date for the freshness flag, since that's when the evidence became checkable.
• Surfshark's newer pentests. Surfshark's trust center lists a 2026 Cure53 infrastructure/Dausos audit and a 2025 SecuRing app-and-infrastructure assessment, but neither page gives a specific month. Some secondary write-ups imply these are very recent; without a dated report, this piece can only confirm the year, not confirm the audit sits inside the fresh window.
• Mullvad's pentest cadence. Search aggregators variously describe Mullvad's most recent infrastructure pentest as a 2024 Cure53 engagement and as a 2024 X41 D-Sec engagement. Mullvad's own published audit log credits the December 2024 infrastructure pentest to X41 D-Sec, not Cure53 — that's the version this piece uses, sourced to Mullvad's own repository rather than the aggregator summaries.

The providers we can't monetize — and why they still win on the evidence

Mullvad and Proton VPN do not pay this site a commission, and it's worth saying plainly: on the documents, they're hard to beat. Mullvad publishes every pentest report it commissions, going back to 2018, in a public repository — no login wall, no summary-only blog post, just the PDFs. Its account-free signup (a randomly generated number, no email required) also means there's structurally less user data for a no-logs attestation to even be about. Proton VPN's Securitum engagement in May 2026 is the freshest no-logs review on this entire list, and Proton has run one annually for five straight years with the reports posted publicly.

That's the standard the rest of the market is being measured against here. A provider that summarizes its audit in a press release but gates the actual report behind a login isn't lying — but it is asking for more trust than a provider that just posts the PDF.

WiTopia's personalVPN, one of the longest-running independent VPN operators, states a no-logs policy on its own site but has no published third-party audit of any kind as of September 2026. That doesn't make the claim false — it means it's a policy statement taken on trust rather than an externally checked one, which is a materially different thing. Readers who specifically want a long-running, independently operated provider and are comfortable with that trade can see WiTopia's current plans; just don't mistake it for an audited pick.

The shortlist, on the documents

Ranked strictly by what's checkable above — not by which provider pays this site more:

1. Proton VPN — freshest no-logs attestation on the list (May 2026), five straight years of published Securitum reports, no commission to this site.
2. Mullvad — every audit since 2018 public with no login wall, account-free architecture, no commission to this site.
3. NordVPN — fresh Deloitte no-logs attestation (Dec 2025) plus a broad 2025 Cure53 app/infrastructure pentest; check NordVPN's current pricing if you want a provider whose most recent evidence is inside the 12-month fresh window.
4. Private Internet Access and CyberGhost — both landed fresh Deloitte no-logs attestations around Q4 2025; worth a look if dedicated-IP features matter to you.
5. Surfshark and ExpressVPN — both have real audit trails, but their headline no-logs attestations are now in the 12-24 month aging band; see Surfshark's current plans if its unlimited-device model outweighs the aging flag for you.

What none of this promises

A clean audit trail says a provider's infrastructure and claimed no-logs architecture checked out on the dates listed. It does not mean the provider can unblock any streaming catalog, and this site won't tell you otherwise — geo-restriction enforcement changes constantly and isn't something an audit measures. It also doesn't mean the connection is fast; if you want speed data, read a named outlet's own dated test (for example, our public Wi-Fi VPN guide cites third-party performance testing directly) rather than trusting an unattributed number. And critically, a VPN — audited or not — is not anonymity. It shifts who can see your traffic from your ISP to your VPN provider; it doesn't erase your digital footprint, and account logins, browser fingerprinting and payment details can still identify you.

FAQ

Does an independent audit mean a VPN provider can never log user data? No. An attestation confirms that the infrastructure and processes examined matched the no-logs policy during the engagement window. It's a snapshot, not a permanent guarantee, which is why this site tracks how old each audit is rather than treating "audited" as a one-time checkbox.

What's the difference between a no-logs attestation and a security pentest? A no-logs attestation (Deloitte, KPMG, Securitum) checks whether described data-handling controls matched reality at a point in time. A penetration test (Cure53, SecuRing, NCC Group) hunts for exploitable vulnerabilities in a specific app, protocol or piece of infrastructure. A provider can have a fresh pentest and a stale no-logs attestation, or the reverse — they're not interchangeable.

Why do Mullvad and Proton VPN rank highly here if this site doesn't earn a commission from them? Because the ranking above is built from published audit dates and report-access policy, not payout. Both publish their reports without a login wall, and Proton's most recent no-logs review is the freshest one in this matrix. Leaving them out to favor a paying provider would make the audit-freshness framework meaningless.

Is a provider without a published audit automatically untrustworthy? Not automatically — but it means the no-logs claim is a policy statement rather than an externally checked one. WiTopia's personalVPN is the clearest example here: a long track record, but no third-party audit report to point to as of September 2026.

Can a VPN make me anonymous online? No. A VPN encrypts your traffic and hides your IP address from sites you visit, but your VPN provider can still technically see your connection (which is exactly what these audits try to verify), and logins, cookies and payment details can still identify you across the internet.
