Abstract
A cloud based data loss prevention (DLP) system implements a split computing architecture using separate indexer system and detection system to perform indexing and data loss prevention monitoring. The cloud DLP system includes a computing system deployed outside of the enterprise data network and including a first computing cluster and a second computing cluster. The first computing cluster includes an indexer system to generate a search index from a pre-index containing hash values of structured data to be protected. The second computing cluster comprises a detection system configured to receive the search index and network data content, to apply a forward hash function based on a key to the network data content, and to detect in the hash values of the network data content for matching data in the search index and to generate an alert in response to matched data content being found in the network data content.
