- Proton VPN has had its non-logs policy audited for the fourth time
- The results confirm that the Swiss -based supplier does not maintain records
- Still considered one of the most respectful of privacy available
Proton VPN has published the results of its last independent audit, confirming that the supplier continues to maintain a strict policy of Non -logs.
Made by Securitum, an independent European audit firm, the August 2025 audit marks the fourth consecutive review of third parties of the Proton VPN non -registration policy. The announcement follows a SOC2 type II audit of July II, 2025, which verified the proper implementation of proton of security controls.
The results of the audit corroborate the statements of Non-Logs of Proton VPN, underlining their continuous commitment to transparency and privacy. This consists in the place of Proton VPN among the best VPN services currently available.
Key Takeways Audit N-Logs of Proton VPN
Securitum, whose customers include Duckdukgo VPN and Hide.me VPN, which went from August 18 to 20 at the site at the Proton Ag headquarters in Zurich, examining the infrastructure of the VPN and the server side operations.
Although Proton VPN works outside Switzerland, where it is not subject to mandatory data retention laws when writing this article, Proton recognizes that the incorrect configuration of the server or other architectural defects could lead to an accidental record.
This is exactly the reason why Proton has taken the step so that its non-Logs policy is regularly audited. As part of this process, Securitum reviewed the Proton VPN configuration files, server settings and operational procedures.
The detailed annual audit was aimed at answering questions, including whether the user activity or connection metadata is recorded on Proton VPN servers, as well as if the non-Logs policy applies to all users, regardless of the subscription level.
In all inspected areas, auditors were able to confirm that Proton VPN does not record user activity or maintain any metadata record, nor participates in practices that may compromise the privacy of their users. Similarly, all users benefit from the same privacy protection, regardless of whether they are paid subscribers or free Proton VPN users.
For more information, here is the full audit report of August 2025.
What this audit means for Proton VPN users
The securitum audit of Proton VPN’s non-logs policy confirms that Proton VPN offers its privacy promises without user activity, metadata or registered traffic, and with safeguards established to maintain this intact guarantee.
That is a guarantee that, even if a hacker or malicious government manages to acquire this data, none of its confidential information will be leaked because these details will simply exist.
While this last audit validates the claim of NO-Logs of Proton VPN, the service’s privacy commitment extends much more.
To start, your applications are open source, which means that anyone can examine their code. The supplier even executes a error reward program, which rewards researchers who discover failures.
You cannot say the same of all VPN, particularly free VPN, which can maintain records that potentially identify it as a user. These data could be sold or shared with third parties, or steal otherwise in a data violation, putting their privacy in the process at risk.
You can access the complete results of all external proton VPN audits, regardless of whether it is an existing subscriber or simply evaluates the service.
