What Beyond Encryption Technologies does

Beyond Encryption Technologies, trading as Beyond Encryption, is a privately held software company headquartered in Fareham, United Kingdom (with an Australian subsidiary, Mailock PTY Ltd.), that operates the Mailock secure email platform. Its core product is built around AES-256 end-to-end email encryption combined with a recipient-first security model — flexible identity verification (including SMS challenges), message tracking with proof of receipt, and post-delivery access revocation. The platform integrates natively with Microsoft 365 and ships an Outlook add-in, enabling secure email workflows without forcing recipients to install separate software or create accounts.

The company serves three primary customer segments: financial services (banks, insurers, wealth managers such as HSBC, Aegon, Royal London, Aviva, Equiniti EQ, abrdn, and Just Group), legal services (law firms and solicitors handling confidential client correspondence), and individual professionals and enterprise teams needing lightweight secure email capability. Mailock is offered through a three-tier pricing model — Free (freemium for individual light users), Pro (subscription for professionals and teams), and Enterprise (multi-year contracts with policy-driven encryption via secure gateway for high-volume deployments).

The business employs 11-50 staff and operates a hybrid go-to-market combining product-led growth through self-serve freemium sign-up with sales-assisted engagement for enterprise deployments. Distribution is amplified through technology partnerships (Microsoft 365, Outlook add-in, Unipass ID), and the company holds ISO 27001, Cyber Essentials Plus, and B Corp certifications. Engagement scale cited on the company's website includes 2,500+ companies, 300K+ registered users, and 3.5M+ recipients served; historical financial backing includes a single disclosed $1.06M funding round from Enterprise Ireland in October 2009.

Direct peers

• Virtru: Provider of end-to-end email and data encryption, including a recipient-friendly experience that does not require recipient accounts. Closely comparable to Mailock's recipient-first encryption model and Google/Microsoft ecosystem integration.
• Zivver: Secure email and file transfer platform focused on healthcare and regulated industries in Europe, with recipient authentication and DLP features. Directly comparable product offering and target verticals (regulated, EU-based) to Beyond Encryption.
• Egress (a KnowBe4 company): Specialist in intelligent email security, encryption, and DLP with strong UK market presence and Microsoft 365 integration — overlapping directly with Beyond Encryption on recipient-aware encryption and misdirected-email prevention.
• Mimecast: Cloud-based email security and archiving vendor providing secure messaging, encryption, and compliance tools to enterprises. Directly comparable to Mailock Enterprise on secure email gateway functionality and target buyer (regulated mid-market and enterprise).
• Proofpoint: Large pure-play email security vendor offering email encryption, DLP, and BEC/phishing protection to enterprises. Closely comparable to Beyond Encryption at the feature level (AES encryption, recipient authentication, policy-driven gateway), but operates at much greater scale and breadth.
• Paubox: Email encryption vendor focused on regulated industries (notably healthcare in the US), providing seamless encryption within existing email workflows. Comparable on recipient-transparent encryption model and vertical-specialisation GTM.
• RMail (RPost): Provides certified secure email, encryption, and e-signature delivery with tracking and proof-of-delivery. Directly comparable on tracked/audited secure email delivery, including legal and financial services use cases.

Emerging players

• SendSafely: Smaller specialist in end-to-end encrypted email and file transfer with strong focus on developer and security-team integrations. Comparable recipient-friendly encryption model, though smaller scale and different buyer profile than Mailock.
• Tuta (Tutanota): End-to-end encrypted email service with native web and mobile clients. Comparable on end-to-end encryption posture, though primarily consumer/SMB-focused and operates a hosted mail service rather than an enterprise gateway overlay like Mailock.

Broad incumbents

• Microsoft (Purview Message Encryption / Microsoft 365): Bundles email encryption, DLP, and compliance features into the Microsoft 365 platform via Purview. Represents the most significant incumbent threat because Microsoft 365 is the underlying email environment where Mailock integrates — and baseline encryption is included in many enterprise plans.
