Quantum-Resistant Security for Your Most Sensitive Communications.

Protect your data. Today and into the future.

Protect your data. Today and into the future.

In a rapidly evolving threat landscape, traditional encryption is no longer enough. Cellcrypt's advanced multi-layered encryption ensures absolute security for governments, defence agencies, and enterprises by safeguarding sensitive communications from today's threats and tomorrow's quantum computing challenges.

Data breaches, interception, and cyber espionage are increasingly common. Quantum computing, specifically, poses a future risk by potentially breaking existing cryptographic standards. To stay ahead, organisations must adopt encryption that's secure against both classical and quantum threats.

With the strongest classical encryption, post-quantum algorithms, and a multi-layer quantum-safe framework, Cellcrypt empowers organisations to stay ahead of tomorrow’s attacks.

Cellcrypt's Multi-Layered Encryption

Classical End-to End Encryption

Classical End-to End Encryption

Built on proven cryptographic advancements and global standards.

  • NIST-certified Algorithms: ECC P-521, AES-256, and ChaCha20.


  • AES (CTR/GCM mode) and ChaCha20 are combined with separate keys to ensure continued security even if one cypher is compromised.


  • Reliable Security: Trusted globally for military-grade security and compliance.


  • End-to-End Protection: Ensures secure communications across voice calls, video, messaging, and file transfers.

Post-Quantum Protection

Post-Quantum Protection

Designed to resist quantum computing attacks, keeping data protected.

  • Integrates CRYSTALS-Kyber and Classic McEliece key encapsulation mechanisms.


  • Prevent Future Decryption: Protects against quantum computing threats, e.g. "harvest-now, decrypt-later" scenarios.


  • Long-term Security: Ensures your data remains confidential even as quantum computing emerges.

Zero-Trust Crypto Architecture

Zero-Trust Crypto Architecture

Proven to meet the standards of government classified networks

  • Session Security: Unique, ephemeral session keys are generated per interaction and are never reused or exposed.


  • Designed with an "assume a breach" philosophy, all data travelling through Cellcrypt's TLS 1.3 and SRTP encrypted tunnels is additionally secured with End-to-End Encryption with Post-Quantum Protection.


  • This removes the reliance on a Walled Garden but can operate securely within one.

Quantum-Agility

Quantum-Agility

A framework for agile post-quantum algorithm integration and replacement.

  • Flexible Framework: Easily integrate new quantum-safe algorithms as standards evolve.


  • Zero Disruption: Algorithm changes don't affect your existing classical encryption layer.

The Evolution of Post-Quantum Cryptography

Pioneering quantum resistance within a commercial secure messaging and communications app, we released our first generation of Post-Quantum Protection within Cellcrypt in 2021.

Cellcrypt has always been at the forefront of secure communications. For over 20 years, our Classical Encryption has consistently exceeded the standards required for the highest levels of government and military-grade security.

The pioneer in providing quantum-resistance within a secure messaging and communications app, we included Post-Quantum Protection within Cellcrypt in late 2020.

Working at the cutting-edge, Cellcrypt's Post-Quantum protection is designed with flexibility in mind. The agile Post-Quantum layer within the Cellcrypt app enables seamless updates and algorithm replacements as global standards evolve, without compromising the integrity of existing classical encryption.

The pioneer in providing quantum-resistance within a secure messaging and communications app, we included Post-Quantum Protection within Cellcrypt in late 2020.

The next phase in the evolution is Coming Soon.
