The recipient experience
Step-by-step
1. Receive
Recipients receive a notification email to let them know they have a secure message waiting to be opened. This message can be customised with your company branding or use the familiar Mailock template.

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

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

Works with...






Compliance
Guarantee email
data compliance
Protect data in line with regulatory guidance.
ICO - GDPR
"Have a policy governing encrypted email, including guidelines that enable staff to understand when they should or should not use it. For example, there may be a guideline stating that any email containing sensitive personal data (either in the body or as an unencrypted attachment) should be sent encrypted."
"[in the event of a data breach] act quickly. Try to recall the email as soon as possible. If you can’t recall it, contact the person who received it and ask them to delete it. The 72 hours following a personal data breach are particularly critical."
FCA - COBS
"Keep a copy of relevant electronic communications, made with, sent from or received on equipment: (1) provided by the firm to an employee or contractor; or (2) the use of which by an employee or contractor has been sanctioned or permitted by the firm."
ESMA - MIFID II
"Have sound security mechanisms in place to guarantee the security and authentication of the means of transfer of information, minimise the risk of data corruption and unauthorised access and to prevent information leakage maintaining the confidentiality of the data at all times.”
