NLP policy isn’t being triggered, and events are undetected

Some events that are submitted for analysis do not trigger policies. Typically, these are NLP or complex policies that use compiled Python scripts. Forcepoint may not be in your system’s pythonpath variable, and NLP uses python.

See the below instructions on modifying the path:
  1. Open the Control Panel and select System.
  2. Click on Advanced System Settings.
  3. Under the Advanced tab, click Environmental Variables.
  4. Ensure that the PYTHONPATH variable includes the following:
    C:\Program Files (x86)\Websense\Data Security\packages;C:\Program Files
(x86)\Websense\Data Security\Scripts\Lib\site-packages;C:\Program Files
(x86)\Websense\Data Security\Scripts;C:\Program Files (x86)\Websense\Data
Security\Scripts\Lib;C:\Program Files (x86)\Websense\Data Security\Scripts\Lib\sitepackages\
win32\lib;C:\Program Files (x86)\Websense\Data Security\Scripts\Lib\sitepackages\
win32;C:\Program Files (x86)\Websense\Data Security\Scripts\DLLs;C:\Program Files
(x86)\Websense\Data Security\policies\scripts
Important: If Forcepoint DLP is installed on a non-default path, edit the paths above to match the install directory of Forcepoint DLP.
