The common methods of storing and sharing sensitive data with colleagues and partners have weak links. Today, files are often encrypted in transit and at rest, but decrypted while in use. This provides hackers and insiders with repeated opportunities to exfiltrate unencrypted data. FHE plugs these holes. It allows the manipulation of data by permissioned parties while it remains encrypted, minimizing the time it exists in its most vulnerable state.

In conjunction with other techniques, FHE also makes it possible to selectively restrict decryption capabilities, so people can see only the portions of a file that they are entitled to, and are necessary for them to do their work.
