Proton

At Proton, security is our highest priority and something that we work on day and night to improve. We have been very fortunate to have several individuals and organizations step forward to assist us with security auditing. The contributors listed below have dedicated their time and effort to helping us and participating in our Bug Bounty program because they believe in online privacy and the right to anonymous email.

If you would like to help audit the Proton Mail code, please reach out and let us know! And if we forgot to mention you below, let us know and we will add you right away, we actually don’t know who some of you are because Proton Mail users are anonymous.
