At Proton(yeni pencere), we believe everyone should be in control of their personal data. A critical component of controlling your data is having the ability to make informed decisions about who you entrust with your data and how it is secured. Most companies rely on security through obscurity and do not share their code, making it impossible for you to accurately assess how secure their service is.
Rather than relying on secrecy to protect our code, we believe in security through transparency, which means we:
- Make all our apps open source to leverage the expertise of IT security experts and the Proton community
- Commission independent security experts to conduct regular audits of our code
- Share the audit reports with the public
By subjecting our apps to rigorous public examination, we ensure that any potential vulnerabilities are swiftly discovered and resolved.
We have previously shared the results of the audits for our Proton Mail(yeni pencere) and Proton VPN(yeni pencere) apps. Now that we have released the new Proton Mail, including Proton Calendar(yeni pencere), we would like to share the results of its audit as well.
The new Proton Mail is secure
Like all Proton applications, the new Proton Mail is open source, and anyone can inspect its code for themselves on GitHub(yeni pencere).
Prior to their release, the source code of both the new Proton Mail and Proton Calendar underwent an extensive security audit. We are happy to announce the final report was overwhelmingly positive, and the audit uncovered no major issues or security vulnerabilities.

This security audit was carried out by Securitum(yeni pencere), a leading European security auditing company. Securitum currently oversees more than 300 security testing projects every year, including for many top European banks.

Security through transparency
Proton Mail was founded by scientists who met at the European Organization for Nuclear Research (CERN), and the scientific principles of peer review and transparency are core values of our team. Just as we would not trust a result without first seeing the underlying data, we do not expect you to trust us without being able to examine our work for yourselves.
If you have questions or comments about the security audit for the new Proton Mail, please share them with us! Join the conversation on Twitter(yeni pencere) and Reddit(yeni pencere).
