What Cellcrypt does
Cellcrypt Ltd is a privately held UK company founded in London in 2005-2006 that develops post-quantum secure communications software for enterprise and government customers. The platform provides end-to-end encrypted voice/video calls, messaging, voice notes, and file transfer protected by dual-layer post-quantum cryptography combining NIST-standardized CRYSTALS-Kyber (lattice-based) and Classic McEliece (code-based) algorithms layered atop AES-256 symmetric encryption and ECDH key exchange. Target customers include government agencies, defense contractors, and Fortune 500 enterprises, with deployment options spanning Swiss-hosted cloud, on-premises, private cloud, and air-gapped networks. The platform holds Common Criteria EAL4+, NATO NIAPC listing, NATO RESTRICTED, and FIPS 140-3 Level 2/3 certifications, positioning it for government and defense procurement.
The product portfolio comprises three deployment tiers: Cellcrypt Enterprise (cloud-hosted, from USD 10/month per user), Cellcrypt On-Premises (self-hosted with custom pricing, white-labelling, and PBX integration), and Cellcrypt Government (from USD 120/year per user, certified for classified communications). A Voice (PBX) Gateway add-on bridges the platform to existing deskphone infrastructure. Live clients include Android and Windows, with iOS, macOS, and Linux listed as Coming Soon. The platform supports a zero-knowledge architecture with device-level key generation, plus SSO, Active Directory/LDAP integration, MDM integration, and centralized administration.
Cellcrypt combines three go-to-market motions: direct enterprise field sales for government and defense accounts, self-serve PLG via enterprise.cellcrypt.com and emp.cellcrypt.io/signup, and marketplace listing on Google Play. Revenue is generated primarily through recurring per-user subscriptions and custom on-premises licensing, supplemented by professional services for implementation and support. The company maintains offices in London, New York, and Brussels, and is led by CEO and Chairman Richard Greco and COO David Rivington. Cellcrypt has raised one disclosed funding round of USD 3.15M from Synergis Technologies in 2007.

Cellcrypt competitors and assessment
Company assessmentDirect peers
- Silent Circle: Silent Circle provides end-to-end encrypted voice, video, messaging, and file transfer for enterprises and governments, with on-premises and Blackphone hardware offerings. It is one of the closest direct competitors to Cellcrypt, serving the same defense/enterprise/government segment with comparable E2EE communications.
- Wickr (Amazon Web Services): AWS Wickr is an enterprise-grade encrypted messaging, voice, and video service with end-to-end encryption, administrative controls, and FedRAMP authorization. Acquired by Amazon in 2021, it directly competes with Cellcrypt in the secure enterprise/government communications market.
- Wire: Wire offers end-to-end encrypted messaging, voice, video, and file sharing for enterprises and governments, with on-premises deployment, MLS protocol support, and ISO/SOC2 certifications. It targets the same regulated, security-conscious customer base as Cellcrypt.
- Threema: Threema is a Swiss-based end-to-end encrypted messenger with Threema Work for enterprise and Threema Education, hosted under Swiss privacy law and offering on-premises options. Its privacy-first positioning and European data sovereignty story closely mirror Cellcrypt's value proposition.
- Signal: Signal is the most widely deployed end-to-end encrypted messaging/voice/video application, with ongoing post-quantum cryptography (PQXDH) implementation. While primarily consumer-focused, it sets the baseline expectation for E2EE and is increasingly referenced as the standard competitors must meet.
- Telegram: Telegram offers Secret Chats with E2EE for messaging and voice calls, with a global user base. Although its threat model and certifications differ from Cellcrypt's, it is a frequent point of comparison for secure messaging buyers evaluating alternatives.
Broad incumbents
- Apple (iMessage / FaceTime): Apple has rolled out PQ3 protocol for iMessage, providing post-quantum end-to-end encryption to its billion-plus user base. It is not a direct enterprise competitor but functions as a broad incumbent baseline that constrains enterprise willingness to pay for premium PQ-only solutions.
- Microsoft (Teams): Microsoft Teams is the dominant enterprise communications platform and is incrementally adding end-to-end encryption and post-quantum capabilities. It competes with Cellcrypt indirectly via its enterprise/government footprint, E5/GCC offerings, and integration with the broader Microsoft 365 compliance stack.
Emerging players
- ID Quantique: ID Quantique is a Swiss quantum cryptography company offering Quantum Key Distribution (QKD) and quantum-safe network encryption. It overlaps with Cellcrypt's quantum-safe positioning but from a hardware/QKD layer rather than a software communications app.
- PQShield: PQShield is a post-quantum cryptography software and IP vendor providing NIST-standardized PQC implementations for chips, devices, and applications. It is an adjacent ecosystem player whose algorithm implementations may be embedded in competing secure communications platforms over time.
