If you’re using a virtual private network to protect your digital life, trust that the provider isn’t secretly recording your every move. Fortunately, one of the best names in the business just proved that its privacy claims are more than just marketing.
Following up on its fourth independent audit last year, Proton VPN has announced that it successfully passed a fifth consecutive annual third-party audit. Conducted by leading European security firm Securitum, the latest independent audit confirmed that the provider strictly adheres to its no-logs policy.
For regular users, this means that the company does not track your IP address, log the websites you visit, or store your DNS queries. If you are looking for best VPN to keep your online habits completely private, this independent verification that a provider actually keeps its promises is exactly what you want to see.
According to Proton, its privacy claims have already been stress tested in the real world. The provider notes that its no-logs policy has been tested in over 400 lawsuits where it was ordered to hand over user data but could not comply simply because the logs did not exist.
Securitum is a heavy hitter in the cybersecurity space, overseeing more than 300 security testing projects each year for large companies and banks. In addition to reviewing Proton VPN’s servers, the audit firm recently conducted a separate security audit of all Proton applications and found no significant vulnerabilities.
Looking under the hood
During this year’s assessment, Securitum experts spent several days on site examining VPN configuration files, assessing operating procedures and interviewing staff to ensure that user data is not being quietly collected.
The assessment also found no persistent records that could tie a specific user to activity performed on a given server.
We are pleased to announce that Proton VPN has passed its 5th annual third-party audit, confirming our strict no-logs policy. Unlike some providers, we openly publish full no-logs reports for anyone to read. Claims should be investigated and verified, including our own.1/2 👇June 16, 2026
Proton’s dedication to peer review stems from its origins; the company was founded by researchers who met at CERN. Because of this, all Proton VPN apps are fully open source, meaning anyone with the technical know-how can inspect the code. The company also runs a bug bounty program to encourage security researchers to find and report potential bugs.
The provider also benefits from being headquartered in Switzerland. Under the current Swiss legal framework, Proton VPN is not subject to any mandatory data retention laws, adding an extra layer of protection for users seeking a strictly private VPN.
Taking a trip to the competition
Alongside the positive review results, Proton VPN took the opportunity to highlight its commitment to transparency while throwing some shade at rival providers.
“Many of our competitors have never been independently audited or have performed a handshake by having their privacy policies audited instead of their actual no-logs infrastructure,” Yen wrote.
Yen also criticized competitors who make their audits difficult to access, noting that some require users to sign non-disclosure agreements or make the reports available only to paying customers. While Proton made the full results fully available here.
