Claim 6:
7. An Advanced Data Protection (ADP) appliance operated by a customer of a cloud-based system, the ADP appliance comprising:
a network interface;
a processor communicatively coupled to the network interface; and
memory storing instructions that, when executed, cause the processor to:
provide a browser-based User Interface (UI) adapted for allowing users to upload data sources and company configurations;
authenticate a user associated with the customer network;
receive a data source for data matching uploaded by the user via the browser-based UI, wherein the data source comprises customer specific sensitive data;
hash the data source with a one-way hash to transform the customer specific sensitive data into a digest, such that the customer specific sensitive data is unreadable by the cloud-based system;
distribute the digest to a central authority of the cloud-based system, wherein the central authority distributes the digest to nodes of the cloud-based system for performing monitoring of content between a client of the customer and an external network by
detecting a presence of the customer specific sensitive data via the data matching using the digest;
receive an updated data source via the browser-based UI;
determine one or more deltas between the data source and the updated data source, wherein the one or more deltas include any of additions, deletions, and updates; and
distribute the one or more deltas to the central authority of the cloud-based system, wherein the central authority distributes the deltas to the nodes of the cloud-based system.
