ProtonVPN Network Overview


ProtonVPN has undergone several independent audits to verify the security and privacy of its service. In 2018, ProtonVPN commissioned Cure53, a leading cybersecurity firm based in Berlin, Germany, to perform a security audit of its infrastructure and client software. The audit found that ProtonVPN’s security practices were in line with industry standards, and it did not identify any major security vulnerabilities.

In 2020, ProtonVPN commissioned the independent cybersecurity firm X41 D-Sec to perform a comprehensive security assessment of its infrastructure and client software. The assessment found that ProtonVPN’s security practices were “exemplary” and that the company had “a clear commitment to the security and privacy of their users.”

ProtonVPN has also undergone a transparency report audit by the firm KPMG, which verified that the company does not collect or store any personal information or metadata about its users.

Overall, the independent audits of ProtonVPN have found that the service is secure and privacy-protective.
