File transfer that is secure AND private
When your business handles sensitive data, “secure” isn’t good enough — you need provable privacy. Hexiosec Transfer is a file sharing solution built from the ground up with true end-to-end encryption (E2EE), ensuring that only you and your intended recipients can ever see your data.
Unlike many “encrypted” tools that decrypt your data on their servers, Hexiosec Transfer never has access to your files — not now, not ever.

What makes Hexiosec Transfer more secure?
- Client-side encryption - Your files are encrypted in your browser before they ever leave your device. We never see your plaintext.
- The decryption key never touches our servers - Keys are embedded in the secure link’s fragment, which your browser never sends to our servers. Even if someone had access to our systems, they couldn’t decrypt your files.
- Zero-knowledge architecture - Because we never have access to your keys or decrypt your content, we have zero visibility of your data, by design.
- Proven cryptography - Hexiosec Transfer uses industry-approved algorithms trusted worldwide: AES-256-GCM encryption, PBKDF2 + HKDF key derivation, and ECDH P-384 for secure key exchange.
Why true end-to-end encryption matters
Many file sharing and “secure” email tools advertise end-to-end encryption, but decrypt your data for virus scanning, indexing, or storage.
That means they can, and do, access your data, even if they imply they won't. It also means an attacker could access your sensitive data, and all their other customers', if their systems are breached.
With Hexiosec Transfer, this can’t happen:
- We never store your keys
- We never decrypt your files
- We can’t read your data
Your privacy is mathematically guaranteed, not merely promised.


Transparency you can trust
We believe security should be provable, not just promised. That’s why our architecture and cryptography choices are publicly documented.
