How it works
Step-by-step
1. Encrypt
Start a secure email with a button in your email client or by using our browser app.

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

3. Engage
Our browser app works just like an email client. Recipients download files, compose, attach, and reply. Any replies will be automatically decrypted into your inbox.

Communicate safely
We feel a lot more secure now we are sending and receiving sensitive client information safely.
Mailock removes a lot of the concern around dealing with everyone’s favourite communication method, which is email. I think it’s very good for a business to be able to demonstrate you have taken steps to protect data and be in line with GDPR."

Outbound security
Multilayer email security
Cybercrime is rising, but it's not the most common cause of data leaks. Emailing the wrong person is the top source of incidents. That's why Mailock Pro doesn't just encrypt, it also protects messages from human error.
Human error
Make sure emails sent to the wrong recipient remain secure. Use multi-factor authentication to verify ID before recipients can gain access. Full Revoke gives you a “last resort” lockdown.

Cyber threat
Fortify your comms against cyber criminals, with NSA-grade AES-256 encryption. Safeguard 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.
