OCR Support for On-Premises (OCR Server Deprecation)
From DLP version 10.4, OCR is done directly over the policy engine. OCR server is no longer in use and will not be available on version 10.4 and above.
For the OCR to work, the administrator MUST configure the desired OCR setting in one of the two options: Policy Engine global settings or on the Supplemental Forcepoint DLP server’s policy engine or the Protector’s policy engine. For more information, see Configuring the Policy Engine.
For customers who enable OCR over protectors on version 10.3 and below, and upgrade to 10.4, it is recommended to upgrade the protectors to version 10.4 or above before upgrading the Supplemental Forcepoint DLP server. Otherwise, the protector’s OCR will stop working as the OCR server will be no longer available on the Supplemental Forcepoint DLP server.
