Talk Freely, Communicate Securely. 


With Post-Quantum Cryptography combined with classical CNSA encryption, your phone calls, video calls, conference calls, messages, and large file transfers are not just secure - they are Quantum-Safe.

But it's not just about securing your communications; it's about managing them too. Cellcrypt provide unrivalled Enterprise Management capabilities.


Encryption for Secure 


Welcome to Cellcrypt.

Secure today, prepared for tomorrow.

Post-Quantum Protection

Post-Quantum Protection

Quantum computing poses an urgent threat: Data encrypted today can be stolen and stored by adversaries, waiting to be decrypted when quantum computers become powerful enough. This can expose your most sensitive information.


Cellcrypt safeguards your data from future quantum attacks with its advanced Post-Quantum Protection. This ensures your sensitive communications remain secure, even in an era of advanced quantum computing

Quantum computing isn't just a future risk; it's a clear and present danger. Data encrypted today could be vulnerable tomorrow. Cellcrypt's Post-Quantum Protection provides future-proof security, ensuring your confidential information remains protected against emerging quantum threats.

This Hybrid Post Quantum Protections bolsters the security of Cellcrypt's cryptography and safeguards your data from quantum threats, without altering the underlying classical CNSA cryptography.

The Cellcrypt Android Mobile Client v4 is eligible to be used as a Voice and Video over IP component in Commercial Soutions for Classifed (CSfC) Solutions.



Cellcrypt is certified by the National Institute of Standards and Technology (NIST) and the Canadian Centre for Cyber Security under the 

Cryptographic Module Validation Program

FIPS 140-2

FIPS Certificate

Cellcrypt is built upon a multi-layered approach to cryptographic security, providing maximum assurance within Zero-Trust Environments, where networks are assumed to be actively compromised.

Adhering to the rigorous standards prescribed by the Commercial National Security Algorithm Suite (CNSA), Cellcrypt enables the safeguarding of Classified Top Secret information, as defined by the National Security Agency (NSA) to protect classified information up to Top Secret.

The cornerstone of Cellcrypt’s security platform is the Cellcrypt Crypto Core, which employs multiple encryption layers to secure data in transit and data at rest.


Incorporating ephemeral key exchange technology, Cellcrypt generates a new key for each individual message, file transfer, or voice call. This systematic process eliminates the need for centralized COMSEC key management, thereby enhancing overall system security.

Encypted Phone Calls & Video Calls

Cellcrypt Video Call

Cellcrypt delivers encrypted phone calls and video calls.


Calls are safeguarded with end-to-end encryption and signal obfuscation, providing the highest level of security through your mobile device's data connection.

But it's not just about securing your calls; it's about enhancing your communication experience. Cellcrypt's cutting-edge phone call encryption codecs ensure high-definition call quality, optimizing data and battery usage even across the most austere, low-bandwidth, mobile / wireless networks.


With Cellcrypt, flexibility is at the forefront. Our platform supports secure calling over an extensive range of IP-based networks, including WiFi, 5G, 4G/LTE, 3G/HSDPA, 2G/EDGE, WiFi, and satellite networks. Moreover, we prioritize the mutual authentication of all call participants to eliminate any potential risks associated with Caller ID spoofing and Man In The Middle (MITM) attacks.

Secure Conference Calls

Experience the unparalleled simplicity of Secure Conference Calls with Cellcrypt.


Our platform allows the swift establishment of a conference bridge directly from the Cellcrypt app. Simply create a group of contacts and press the call button - it's as straightforward as that.

We've eliminated the hassles of participant PINs and passwords by ensuring that only mutually authenticated, authorized users can join your Cellcrypt conference calls. This not only streamlines the connection process but significantly enhances the security of your meetings.

Moreover, our Cellcrypt Voice Gateway extends these security measures to your physical office space. PBX-connected desk phones and conference phones can seamlessly join a Cellcrypt conference call, and Cellcrypt users can also join PBX-hosted conference calls, bridging the gap between your in-house and remote teams.
