Details:
Endpoint DLP now includes a pre curated list of file extensions for the file extension condition. Previously, file extensions were entered as free form text, which could result in unsupported or non-scannable extensions being used. This could lead to gaps in protection and increase processing overhead on endpoints. With the pre curated list, you can select only supported file extensions. This helps improve policy reliability and reduces unnecessary processing on endpoints.

Increased Risk of Data Loss
If the change to a pre curated list of file extensions is implemented without proper preparation, users may inadvertently attempt to use unsupported file extensions, leading to potential data loss as these files may not be adequately protected by the DLP policies.

User Experience Disruption
The transition to a pre curated list may confuse users who are accustomed to entering file extensions freely. This could lead to frustration and decreased productivity as users may not understand why their files are being blocked or not scanned.
