We Partner with Sefas to Transform Customer Communication Security

We’ve partnered with Sefas to offer a smarter, safer way to deliver sensitive customer documents by email, at scale.

Every day, businesses send documents that really matter. A policy renewal, a pension update, a payment reminder.

For customers, these messages carry weight. But for organisations, making sure they’re delivered securely - and in the right way - is getting harder.

That’s why we’ve joined forces with Sefas, a leader in Customer Communications Management (CCM), to help organisations send protected, personalised messages without compromising speed or compliance.

What’s the Partnership About?

Sefas’s Harmonie Communication Suite (HCS) gives organisations a way to produce and manage essential customer documents, across print and digital channels, from a single platform.

Now, using Mailock, those documents can be delivered securely via email - encrypted end-to-end, with multi-factor authentication and audit tracking.

It’s a secure solution that works behind the scenes, making things safer for customers and simpler for teams.

Benefits for organisations include:

• Encrypt documents with AES-256 security, automatically.
• Apply multi-factor authentication to confirm recipient identity.
• Track delivery and access with read receipts and audit logs.
• Reduce costs and carbon by switching from print to digital.
• Tailor the experience to reflect your brand.
• Stay compliant with UK and EU data rules.

Why It Matters

Security and simplicity don’t always go hand in hand.

If a secure system is slow or clunky, teams will find workarounds. If it’s confusing for customers, trust breaks down.

That’s the gap this partnership closes. By integrating Mailock into HCS, we’re making sure sensitive documents are encrypted and verified without adding friction - or needing a new system to manage it all.

"Security and trust sit at the heart of every customer relationship. By combining Mailock’s secure communication capabilities with Sefas’s class-leading CCM platform, we’re giving organisations a seamless way to protect their most valuable asset - their customer communications."

"We’re embedding security right into the flow of communication - no extra steps, no compromises. This is how secure email should work for high-volume organisations."

What It Means for Businesses

Many organisations are trying to modernise communications - but legacy systems, tight budgets, and regulatory pressure can get in the way.

Our combined solution works with existing infrastructure, helping teams add secure email delivery into their workflows with minimal disruption.

It’s built for the real world - for banks sending statements, pension providers issuing updates, and legal firms sharing valuable documents that need to be protected.

"We’re delighted to be strengthening our collaboration with Beyond Encryption. Together, we’re helping businesses shape better journeys for their customers through secure, scalable, omnichannel communication."
