2. Authentication

Recipients click ‘Open’ on the notification delivered to their inbox. They’ll answer an identity challenge, or if they're trusted, they can read right away.

Lower costs

Through our consultancy process, we found that for businesses with high outputs, secure email generates 95% savings on print, pack, and post.


Carbon savings

Taking into account the full lifecycle of paper production and delivery, secure email helps businesses to reduce their carbon impact by over 80%.

Protect data

Do your duty to protect data in line with regulatory guidance (FCA/ICO).

Encrypt personal information (GDPR)

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).

Record proof-of-delivery (MIFID II)

All businesses should record digital communications and retain proof-of-delivery to align with ICO guidance. Proof-of-receipt is required by the FCA for certain types of document (e.g., KIDs).

Protect customers (Consumer Duty)

Are you encouraging customers to send their information into your business unsecured? The FCA Consumer Duty is a mandate to provide easy-to-understand communications and protect customers from financial harm.
