At ProtonMail, 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. We are a small group that is largely supported by donations and grants so we typically do not offer financial incentives to security contributors. While we do have an unofficial bug bounty program, most of the contributors listed below have donated their time and effort because they believe in online privacy and the right to anonymous email.
If you would like to help audit the ProtonMail 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 ProtonMail users are anonymous.
