Compliance

Regulatory guidance

A secure email service that helps you comply with data protection regulations.

GDPR - Encrypt personal information

The Information Commissioner's Office (ICO) and Financial Conduct Authority (FCA) require businesses to encrypt sensitive data transferred digitally. The ICO can levy fines of up to £17m for non-compliance (or 4% of turnover). Mailock protects your data with military grade AES-256 encryption.

MIFID II - Record proof-of-delivery

All businesses should record digital communications and retain proof-of-delivery to align with ICO guidance. Proof-of-receipt is also required by the FCA for certain types of document (e.g., KIDs). Mailock tracks every sent item - from delivery through to the exact date and time it’s opened by your recipient.

Consumer Duty - Protect customers

Are you encouraging customers to send their information into your business unsecured? The FCA's Consumer Duty is a mandate to provide easy-to-understand communications and protect customers from financial harm. Mailock makes it easy for you to delivery communications via your customers' channel of choice - email.

Testimonial

It's become a critical part of our processes

It hasn’t changed the way we work. Email is how most of our clients want to communicate and Mailock enables us to do that securely.
