Introducing Mailock Free

Mailock Free gives individuals and businesses a no-cost way to send up to five secure emails each month, attachments included.

In September 2022, Beyond Encryption launched Mailock Free so advisers, providers, and consumers could send sensitive documents outbound without waiting for a firm to initiate secure email first.

Mailock already supports secure communication for household names including Aegon, HSBC, and Royal London, working with partners such as Origo and Paragon Customer Communications. Mailock Free extends that capability to anyone who needs occasional secure outbound email.

What Is Mailock Free?

Mailock Free lets users send up to five secure messages each month, complete with attachments.

That gives advisers, providers, and consumers a practical route to secure outbound email without relying on the recipient to start the exchange.

The free version uses the same AES-256 encryption as paid Mailock licences, with protected access to help keep sensitive content controlled.

Mailock works inside Microsoft Outlook, and senders can identify recipients using a secure Question & Answer authentication method.

Mailock Free sits alongside the secure email capability already used by major financial services firms and their partners.

Why We’re Offering a Free Version

Digital activity has risen alongside a significant increase in cyber attacks, and many organisations now face sharper questions about how customer data is handled in everyday communication.

ICO guidance on data protection puts clearer pressure on firms to protect personal information, including when customers send confidential or personally identifiable data back by email.

Mailock Free addresses that gap by giving individuals and organisations a simple way to send sensitive information securely, without paying for a full licence when their needs are occasional.

Who Can Use It?

Mailock Free is available to individuals and organisations that need secure email for low-volume outbound communication.

If you need to send more than five secure emails per month, or access additional features like sender company branding, SMS recipient authentication, email recall, and security alerts, paid upgrade options are available.

Those tools support businesses and individuals with higher security or volume requirements.

“Our goal is to make digital security accessible and affordable for all.

Consumers need a practical way to send documents to companies securely, as well as receive them.

Communication works both ways, and both ends need protection.”

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

For commercial and delivery teams, Mailock Free is designed as a practical entry point before higher-volume secure email use.

“Mailock Free gives individuals and businesses a straightforward route into secure outbound email.

For organisations already using Mailock at scale, it helps close the gap when clients, advisers, or providers need to send sensitive information back without committing to a full licence straight away.”

Adam Byford, COO, Beyond Encryption (Mailock)

That entry point builds on the same secure email infrastructure Mailock already delivers through enterprise deployments and industry partnerships.

From Enterprise Mailock To Mailock Free

Mailock Free extends the same secure email approach used by firms such as Aegon, HSBC, and Royal London to anyone who needs occasional protected outbound communication.

Together with partners including Origo and Paragon Customer Communications, that gives more senders a practical way to protect sensitive information by email.
