Confidential Zero-Knowledge File Transfer for Legal Practices
Legal privilege, attorney-client confidentiality, and strict NDAs require that sensitive evidentiary documents, depositions, and litigation discoveries never exist in plaintext on third-party cloud servers. LimeShare's zero-knowledge pipeline guarantees that only sender and recipient hold decryption keys.
