We Partner with Sefas to Transform Customer Communication Security

Mailock is now integrated with Sefas's Harmonie Communication Suite (HCS) so organisations can deliver sensitive customer documents by secure 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. For organisations, getting delivery secure and consistent across print and digital channels is getting harder.

That's why Beyond Encryption and Sefas announced this partnership to connect Mailock with Sefas's Customer Communications Management (CCM) platform, helping 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.

Using Mailock, those documents can be delivered securely via email - with AES-256 encryption, multi-factor authentication, and audit tracking.

The integration works behind the scenes, so teams can add protected email delivery without rebuilding their document workflows.

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.
• Help support compliance expectations under UK and EU data rules.

Secure Document Delivery Without Extra Workflow Friction

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.

Integrating Mailock into HCS is designed to keep sensitive documents encrypted and verified without adding friction - or needing a separate system to manage delivery.

"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."

Paul Holland, Founder and CEO, Beyond Encryption (Mailock)

"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."

Mike Wakefield, Chief Technology Officer, Beyond Encryption (Mailock)

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.

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

It fits high-volume use cases already common in regulated sectors - banks sending statements, pension providers issuing updates, and legal firms sharing documents that need protected access.

"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."

Dave Chilman, COO, Sefas UK
