Encryption is the conversion of data into a form called ciphertext, that cannot be read by unauthorized people. There are different forms of encryption for files, including whole disk encryption and per-file encryption. Both can be used to help protect your data from being compromised or exposed.

Whole Disk Encryption


Enable whole disk encryption on portable devices (laptops, tablets, phones) and for high risk data additionally on portable media (USB drives). This protects your entire device, and lets you unlock it with a password.

File Level Encryption (Encryption for File Sharing)

File level encryption is the encryption of a single file for sharing that can be decrypted using a key. Use file level encryption when sharing high risk files on platforms like email, Dropbox, and Slack. Encryption keys must be shared via another method. Sending them with the files you've encrypted isn't offers no protection against compromise when the files and the key to decrypt them are kept together.
