- Proton VPN Passes Fifth Annual Independent Audit Without Logs
- Audit confirms that the provider does not record any user identifiable data
- Proton openly released the full report, criticizing competitors for not doing so
If you’re using a virtual private network to protect your digital life, you need to be sure that the provider isn’t secretly recording your every move. Luckily, one of the biggest names in the industry just proved that its privacy claims are more than just marketing talk.
Following its fourth independent audit last year, Proton VPN announced that it has successfully completed a fifth consecutive annual third-party review. Carried out by Securitum, a leading security company in Europe, the latest independent audit confirmed that the provider strictly adheres to its no-logging policy.
This means the company doesn’t track your IP address, log the websites you visit, or store your DNS queries. If you are looking for the best VPN to keep your online habits completely private, this independent verification that a provider actually delivers on its promises is exactly what you want to see.
According to Proton, its privacy claims have already been tested in the real world. The vendor notes that its no-logging policy has been tested in more than 400 legal cases in which it was ordered to provide user data, but was unable to comply simply because the logs did not exist.
Securitum is a major player in the field of cybersecurity, overseeing more than 300 security testing projects for large companies and banks each year. In addition to examining Proton VPN’s servers, the auditing firm recently conducted a separate security audit of all Proton applications and found no significant vulnerabilities.
Look under the hood
During this year’s assessment, Securitum experts spent several days on site reviewing VPN configuration files, evaluating operational procedures, and interviewing staff to ensure user data is not being collected silently.
The assessment also found no persistent records that could link 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-logging policy. Unlike some vendors, we openly publish comprehensive no-logging reports for anyone to read. Claims should be investigated and verified, including ours.1/2 👇June 16, 2026
Proton’s commitment to peer review stems from its origins; the company was founded by scientists meeting at CERN. For this reason, all Proton VPN apps are completely 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 vulnerabilities.
The supplier also benefits from its headquarters in Switzerland. Under the current Swiss legal framework, Proton VPN is not subject to any mandatory data retention laws, which adds an extra layer of protection for users looking for a strictly private VPN.
Get a kick-off at the competition
Alongside the positive audit results, Proton VPN took the opportunity to highlight its commitment to transparency, while also throwing some shade at competing providers.
“Many of our competitors have never been independently audited or have taken a sleight of hand by having their privacy policy audited instead of their actual infrastructure without logs,” Yen wrote.
Yen also criticized competitors that make their audits difficult to access, noting that some require users to sign nondisclosure agreements or only make reports available to paying customers. While Proton has made the full results fully accessible here.
