Applying data-centric encryption directly to files is a robust method for protecting unstructured data in the cloud. This approach focuses on the data itself rather than the perimeter or environment in which it resides. Data-centric encryption ensures that sensitive information is encrypted at the file level, meaning that even if unauthorized access occurs, the files remain protected because they can only be read by individuals or systems with the correct decryption keys.

This method is especially effective for unstructured data, which often includes documents, images, and other files that may contain sensitive information. By encrypting the data, organizations can maintain confidentiality and comply with data protection regulations, as the data is rendered unintelligible to those without the proper credentials.

In contrast, methods like data masking are used to obfuscate specific elements of the data for use in non-production environments but do not provide true confidentiality of the data itself. File permissions help control access to files but do not encrypt the data, which leaves it vulnerable if access controls are bypassed. Data loss prevention solutions are designed to monitor and protect against unauthorized transmission of data but also do not provide direct encryption of the files themselves.
