How it works

1. Encrypt

Start a secure email from Windows Outlook or use our browser app. Set a challenge so only the right people gain access.

Start a secure email with a button in your email client

2. Connect

Recipients click ‘Open’ on the notification delivered to their inbox. They’ll answer any challenges that have been set, or if they're trusted, they can open and read right away.

Enter the code to unlock your secure email

3. Engage

If recipients need to reply to a secure message, they can use Mailock to compose, attach, and reply using their existing email address and account. They'll even get a limited number of secure emails to send.

Trigger words
