Our Mission

Email encryption is broken, with too many steps required for users to send and view emails. The result is a vulnerable system open to cyberattacks that costs individuals and companies billions of dollars each year.

We want to secure every email by increasing the adoption of encryption. We do this by putting the user experience first, but not at the expense of security. We want to start with the healthcare industry, which is under attack by hackers who value the personal health information of patients.
