A firm wants encrypted mail, but its clients won't generate a PGP key. CipherMail solves this by sitting between the mail client and the world: an SMTP/IMAP proxy that encrypts on the fly.
How it works
- On send, we check whether the recipient has a public key in the directory.
- If yes → the body is encrypted (PGP, or S/MIME if configured).
- If not → the message goes in clear but raises a compliance alert on the admin side.
Why a proxy, not a new client
Adoption is the real lock. If the team must switch tools, the project dies. By staying transparent (standard IMAP/SMTP), CipherMail plugs in without training anyone.
Known limit
The weak link is still the correspondent who replies in clear. The proxy alerts, but doesn't force the other end — that isn't its job.
