Security and confidentiality guaranteed

End-to-end encryption with hybrid post-quantum keys and zero-knowledge architecture. Your data is protected by cutting-edge cryptography that we cannot circumvent, even if asked.

    Protection against current and future threats. Your files are encrypted before sending with hybrid post-quantum keys MLKEM768-X25519 (X-Wing).
    Zero-knowledge architecture

    Public white paper
    Architecture, cryptographic model and zero-knowledge guarantees are detailed in a freely available white paper.
