KyberCrypt

Secure file sharing for law firms

Collect documents from clients, exchange files with co-counsel, and deliver work product — all sealed with encryption strong enough for privileged material, and a record you can stand behind.

Client intake without the friction

Send a client a secure request link. They upload from their browser — no account, no software — and the file is sealed to your keys and lands in your inbox. Turn on maximum-privacy mode and the file is encrypted in the client's browser before it's uploaded, so it reaches you as ciphertext we never see.

Confidentiality by default

Attorney-client privilege deserves more than transport encryption. Every file is sealed to the recipient with hybrid post-quantum cryptography (ML-KEM-768 + X25519), stored only as ciphertext, and deleted the moment it's downloaded — nothing lingers on a server waiting to be breached or subpoenaed.

A record you can defend

Every upload, download, and link event is written to a tamper-evident, hash-chained audit log you can export for the matter file. Add branded client portals so intake looks like an extension of your firm, not a third-party tool.
