If an unsafe file gets uploaded to a cloud-based collaboration app, it can spread to your entire organization in an instant. But with our sandboxing and analytics, you can contain those malicious files in the cloud through an automated quarantine and other mitigation steps.

Our robust policy capabilities alert you to issues in real time. And to prevent unauthorized or risky access, you can apply adaptive access controls. These include enforcing multi-factor authentication and restricting access from unmanaged devices.   

Risk-Aware Data Security

As more of your organization’s data is stored in the cloud, so is sensitive content. Proofpoint CASB has hundreds of built-in DLP classifiers, dictionaries, rules and templates to help you speed up PCI, PII, PHI and GDPR compliance. Custom contextual rules allow you to build your own DLP policies to control how your data is shared or downloaded.
