Case Study: Corelight achieves comprehensive cloud data visibility and proactive risk mitigation with Proofpoint DSPM

Improving Visibility to Transform Data Security With Proofpoint

Corelight, an open‑core network security company founded by the creators of Zeek and serving Fortune 500, government and research customers, needed better visibility into its cloud data and risk posture. CISO Bernard Brantley sought a scalable, customizable solution to identify sensitive structured and unstructured data, map assets and access, detect misconfigurations, and enable faster detection, response and executive reporting—limitations that manual processes, open‑source options and basic CSPM tools could not meet.

Corelight deployed Proofpoint Data Security Posture Management (DSPM). Proofpoint’s agentless scanner and knowledge graph mapped data, identities, assets and attack paths, prioritized risks, and automated remediation and ticketing. The platform quickly revealed unexpected sensitive data locations, delivered context‑aware insights for decision‑making, and enabled continuous, proactive protection across Corelight’s cloud environment, with plans to expand across its AWS infrastructure.
