Cloudflare CASB
A modern, SASE-native cloud access security broker (CASB)
Our CASB provides comprehensive visibility and control over your SaaS applications, so you can easily eliminate the risk of compromise, prevent data loss, and avoid compliance violations.
Benefits of Cloudflare Casb
Comprehensive visibility and control
Use our API integrations to continuously scan SaaS applications for misconfigurations, exposed files, and suspicious activity — and remediate risks as they arise.
Regulate access control
Apply identity-aware, context-driven Zero Trust policies to control how and where users access your applications.
Granular data protection
Apply consistent, granular DLP controls across cloud applications to block accidental or risky data sharing.
Simplified compliance
Ensure better visibility across your application portfolio to minimize data loss and meet compliance requirements — including GDPR, CCPA, HIPAA, and more.
HOW IT WORKS
Simplify the way you protect your SaaS applications
Cloudflare’s multimode CASB helps deliver unified cloud security for SaaS applications. To secure data at rest, simple API integrations continuously scan your applications for vulnerabilities and potential risks.
Our Zero Trust access (ZTNA), gateway (SWG), and browser isolation (RBI) controls are seamlessly deployed as an inline CASB — no additional configurations needed.

Control application access
Identify which SaaS, web, and private applications users are accessing — then apply data controls and identity/device-driven policies to shrink your attack surface.
Safeguard valuable IP and developer code
Prevent users from sharing sensitive data in SaaS apps, and easily detect and remediate misconfigurations that risk data exposure and code leaks.
