Profile settings
This page lists the advanced settings available when configuring a predefined or custom DLP profile.
Match count refers to the number of times that any enabled entry in the profile can be detected before an action is triggered, such as blocking or logging. For example, if you select a match count of 10, the scanned file or HTTP body must contain 11 or more matching strings. Detections do not have to be unique.
Context analysis restricts DLP detections based on proximity keywords. Additional proximity keywords must be detected within a distance of 1000 bytes (~1000 characters) from the original detection to trigger an action. For example, the string 123-45-6789 will only count as a detection if in proximity to keywords such as ssn.
Additionally, you can control context analysis for scans within files. When files are excluded from the context filter, DLP only evaluates uploaded and downloaded files based on regular expression and validation checks. Additional keywords within the file are not required.
Optical Character Recognition (OCR) analyzes and interprets text within image files. When used with DLP profiles, OCR can detect sensitive data within images your users upload.
OCR supports scanning .jpg/.jpeg and .png files between 4 KB and 1 MB in size. Text is encoded in UTF-8 format, including support for non-Latin characters.
