How it works

Step-by-step

1. Encrypt

Start a secure email with the click of a button in Outlook, compose, and send. Get prompts to encrypt if Mailock thinks you might be sending sensitive information unsecured.

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 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, they are automatically decrypted into your Outlook inbox.

Easy and efficient

"I just think about it as being email."

It hasn’t changed the way we work. Email is still the way most of our clients want to communicate. It’s been around for so long now, it’s just second nature. It’s a failsafe. I don’t have a peer system for checking emails, so this acts as a second pair of eyes."

Protect data

Free your business from open-risk email. Protect messages and files from cyber threat and human error. Exchange documents with customers and keep their data safe 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.
