Comply with

regulatory guidance

Keep an irrefutable record of message opens, attachment downloads, and revoke calls with secure audit trails. In regulated sectors, proof-of-delivery is paramount.

audit trails with Mailock


"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."


"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."


"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.”

How it works

1. Delivery

Route your sensitive document output through the Mailock network, providing any details needed to authenticate recipients in the process.

2. Authentication

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.

3. Response

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.
