Secure File Sharing for Enterprises
Secure File Transfer
Cellcrypt provides military-grade file sharing that protects your most sensitive documents, images, videos, and data from interception, unauthorised access, and cyber threats. Our zero-trust file transfer ensures that sensitive documents never fall into the wrong hands, regardless of file size or network conditions.
Any File Type
Documents, images, videos, archives - all file types supported
Large Files (500MB+)
Transfer large files without size restrictions or compression
End-to-End Encrypted
Files encrypted before transmission and decrypted only by recipient
Why Choose Cellcrypt for Secure File Transfer?
Traditional file sharing services expose your data to significant security risks. Cloud storage providers, email attachments, and consumer file sharing apps often store files in plaintext on their servers, making them vulnerable to data breaches, government surveillance, and insider threats.
Cellcrypt's secure file transfer goes beyond basic encryption by implementing a zero-trust architecture where files are encrypted on your device before transmission and can only be decrypted by the intended recipient. No third party—including Cellcrypt—can access your file contents.
Whether you're sharing classified government documents, sensitive financial reports, medical records, or confidential business plans, Cellcrypt ensures your files remain private and tamper-proof throughout the entire transfer process.
Key Features:
End-to-End File Encryption
Files are encrypted on your device using military-grade AES-256 and ChaCha20 encryption before they leave your device.
Unlimited File Size
Transfer files of any size, from small documents to large video files and database backups.
Post-Quantum Security
Built-in protection against future quantum computing attacks using CRYSTALS-Kyber and Classic McEliece algorithms.
Secure Store-and-Forward
Files are securely stored (encrypted) if the recipient is offline and auto-delivered when they come online.
Cross-Platform Compatibility
Send and receive files across smartphones, tablets, desktops, and enterprise systems.
Audit Trail & Compliance
Complete audit logging for regulatory compliance with HIPAA, SOX, FIPS 140-3 Validated, CAVP Algorithms, and government security standards.
File Integrity Verification
Cryptographic checksums ensure files haven't been tampered with during transmission.
How it Works: Zero-Trust File Transfer
Cellcrypt's file transfer architecture is designed around the principle of zero trust—assuming that networks, servers, and even our own infrastructure could be compromised. Here's how we protect your files at every step:
Client-Side Encryption
Before your file ever leaves your device, it's encrypted using AES-256 and ChaCha20 encryption with a unique, randomly generated key. This happens entirely on your device—the plaintext file never touches our servers or travels across any network unencrypted.
Secure Key Exchange
The encryption key used to protect your file is securely shared with the recipient using post-quantum secure key exchange protocols. The key is never stored on any server and is transmitted through a separate, encrypted channel from the file itself.
Encrypted Transit & Storage
Your encrypted file is transmitted over TLS-secured channels and stored (still encrypted) on our servers only temporarily. Even if our servers were compromised, attackers would only see encrypted data that's cryptographically useless without the keys—which are never stored with us.
Recipient-Only Decryption
When the recipient downloads the file, it's decrypted entirely on their device using the secure key they received. Only they can decrypt the file—not Cellcrypt, not network administrators, not government agencies—ensuring true end-to-end confidentiality.
Automatic Secure Deletion
After successful delivery or expiration, encrypted files are permanently deleted from our servers using secure deletion methods. No traces of your data remain in our infrastructure, providing perfect forward secrecy for your file transfers.
