A Guide to Modern File-Level Encryption

What is file-level encryption?

File-level encryption has long been a common technique to protect file confidentiality and sensitive data at rest. It ensures that selected information is unreadable to unauthorized viewers, regardless of where it’s stored. In contrast to full-disk encryption, where entire partitions or disks are protected, file-level encryption (FLE) protects data in specific files, folders, or storage locations. It also protects the metadata of those files or locations.
