The Document Sharing Problem

Email is unencrypted by default. Cloud links can be forwarded. Messaging apps retain copies. None provide the combination of encryption, access control, and automatic expiration that sensitive documents require.

Secure Sharing Methods

For immediate sharing: ZeroLatch encrypted vault with separate password channel. For ongoing sharing: encrypted cloud folder (Tresorit, Proton Drive). For conditional sharing: dead man's switch delivery. For large files: encrypted transfer services with expiration.

Key principle: Always separate the encrypted file from the encryption key.

Choosing the Right Method

Tax docs: encrypted vault. Medical records: secure portal. Legal documents: dead man's switch. Passwords: password manager shared vault. Large media: encrypted transfer with expiration.
