Encryption is a vital cybersecurity safeguard that protects data while at rest on your device and in transit across a network.
Made possible by cryptography, the technique of applying an algorithm to scramble data in a way that only an authenticated recipient with a key can unscramble or decrypt, encryption makes data unreadable to others.
To ensure that private information remains private, utilize Full Disk Encryption (FDE) on your device as well as end-to-end encryption (such as O365 OME) when sending sensitive data via email.
