On an endpoint that encrypts local files to protect against data leakage and other harmful malware events, newly detected files are dynamically encrypted when they are detected as long as the endpoint is not compromised. If a compromised state is detected, the newly detected file will not be added to the encrypted files until the endpoint can be remediated and the compromised state resolved.

Just-in-time encryption

Transparent file processing is supported in Unix-like operating systems by emulating the desired file processing through a number of recipes that accommodate different contexts. Recipes are provided, for example, for local folders in user space, for whole devices (e.g., flash drives or network drives), and for folders synchronized to cloud data. By detecting the path type for a file operation and selecting and applying the appropriate recipe, file processing can be performed in a manner transparent to the user.
