Proofpoint Cloud App Security Broker review
A broad CASB for cloud visibility, data protection and account-threat response.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Proofpoint Cloud App Security Broker is a hybrid CASB for organizations managing enterprise SaaS and IaaS applications. It protects cloud users, applications and data against threats, data loss and compliance risks. The product brings together cloud application and user visibility, shadow IT and third-party OAuth application discovery, cloud DLP policies and classifiers, adaptive access controls, malicious-file quarantine, and account-takeover detection. It is best suited to teams that need both cloud data protection and account-threat controls across their environment.
Its standout capability is the combination of preventive controls and automated response. Inline DLP applies controls within cloud applications, while API controls extend protection through connected services. Adaptive access can respond to access conditions, and the product can detect and quarantine malicious files. Automated remediation addresses risky sharing, permissions and OAuth access. Timeline-based reporting connects cloud threats and data-loss activity, giving security teams a way to review related events rather than treating each control as an isolated function.
Platform fit is a central part of the product’s design. It integrates with Microsoft 365, Google Workspace and Okta, along with Proofpoint Information Protection, Targeted Attack Protection, Cloud Security, Threat Response and Emerging Threat Intelligence. Security telemetry can also connect with SIEMs, SOARs, ticketing systems and messaging systems. Deployment options include API connectors, adaptive access controls and cloud proxy models. According to the vendor’s pricing model, buyers contact sales rather than selecting a published self-service plan. Choose it when cloud applications, data loss, OAuth governance and account threats need to be managed together; choose a narrower tool when only one of those controls is required.
