How it works
Step-by-step
1. Encrypt
Start an encrypted message with the click of a button in your email client, compose, and send. Get prompts to encrypt if Mailock thinks you might be sending sensitive information.

2. Connect
Recipients click ‘Open’ on the digital envelope delivered to their inbox to start the Mailock in-browser app. Set challenges to verify their identity - or, if they're a trusted contact, they can decrypt and read right away.

3. Engage
Our browser app works just like an email client. Recipients download files, compose, attach, and reply. When you receive their replies and attachments, they are automatically decrypted into your inbox.




2-Factor Authentication
Make sure the right person is reading
Set read challenges for recipients
- SMS: Send a one-time code to your recipient's mobile phone or tablet.
- Q&A: Ask your recipient a question only they could correctly answer.

Smart alerts
Prevent a leak
before it happens
Get reminders to encrypt sensitive info
If Mailock thinks it sees sensitive information in your email, it'll tell you. Smart alerts prevent data leaks and they train you and your colleagues to become more intentional about what you send over open-risk email.

Protection
Multilayer email security
Cybercrime is rising, but it's not the most common reason for data loss. Emailing the wrong person is the primary cause of incidents. That's why our Mailock for Outlook add-in doesn't just encrypt, it also protects messages from human error.
Human error
Make sure emails sent to the wrong recipient remain secure. Use 2-factor authentication so only the right people can gain access. Full Revoke provides you with a last resort option to strip access.

Cyber threat
Fortify your comms against bad actors, with military-grade AES-256 encryption. Mailock safeguards your confidential data on its journey and at rest on your mail server and in your recipients' inboxes.

Risk training
Customisable security alerts train employees at the point of sending to encrypt emails containing sensitive data. Mailock scans your emails for key information that your business considers sensitive to prevent data loss.
