“Personal data shall be: processed in a manner that ensures appropriate security of the personal data, including protection against unauthorised or unlawful processing and against accidental loss, destruction or damage, using appropriate technical or organisational measures ('integrity and confidentiality').” — ICO, 2021


“An investment firm shall 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.” — ESMA, 2021

ISO 27001

“You should use encrypted communication channels when transmitting personal data. You should have an encryption policy in place that governs how and when you implement encryption, and you should also train your staff in the use and importance of encryption. When storing or transmitting personal data, you should use encryption and ensure that your encryption solution meets current standards.” — ICO, 2021


Transform your communications

Make email a force for good, meet your goals, and reduce your costs while you're at it.


Reach ESG goals

Strengthen your environmental, social, and governance proposition. Businesses with strong ESG goals achieve higher equity returns and reductions in bottom-line risk.


Cut operational costs

Over 9.5 million documents are sent in the UK each year, the vast majority by businesses. In the UK financial services industry alone, digitising print and post operations could save £1.3 bn.


Protect data

The most common cause of data exposure is sending an email to the wrong person. Protect your staff and any sensitive information you send with identity authentication and full revoke.


Protect against

... things that shouldn't keep you up at night.

Human error

Keep company data secure with digital identity authentication, ensuring even emails sent to the wrong recipient remain secure.


Fortify your business against bad actors. With military-grade encryption, Mailock safeguards your confidential data on its digital journey.
