CASB

A modern, SASE-native cloud access security broker

Identify security posture risks within SaaS applications, GenAI tools, and cloud environments. Find and remediate misconfigurations and data security issues that create risk.

Comprehensive visibility

Pinpoint misconfigurations, exposed files, and suspicious activity in SaaS apps and cloud environments — and remediate risks as they arise.

SaaS access control

Apply inline, context-driven zero trust policies to control which users and devices access your internal resources.

Granular data protection

Scan for sensitive data at rest, and apply consistent DLP controls across environments to block accidental or risky data sharing.

Simpler compliance

Help meet regulatory compliance requirements with better SaaS and cloud visibility to assess risk, remediate posture issues, and maintain audit trails.

Background Pattern

You can use CASB to:

See reference architecture

Manage security posture of AI tools

Jumpstart your AI security posture management (AI-SPM) strategy by detecting GenAI-specific configuration risks across popular AI tools such as ChatGPT, Claude, Gemini, and Copilot.

Control application access

Provide least privilege access to SaaS and cloud apps, then track security posture findings and remediate issues to shrink your attack surface.

Safeguard valuable IP and developer code

Detect sensitive data at rest in files stored in SaaS and cloud apps. Find and fix issues that risk data exposure and code leaks.

Discover shadow IT

Get visibility into sanctioned and unsanctioned SaaS, cloud, and AI usage, then block risky apps or redirect users to approved alternatives.

Frequently asked questions

Cloudflare CASB (cloud access security broker) is a modern, SASE-native security solution that identifies risks across SaaS applications, Generative AI tools, and cloud environments. It provides comprehensive visibility to pinpoint misconfigurations, expose suspicious activity, and enforce inline zero trust access controls.
In Cloudflare CASB, posture findings refer to detected misconfigurations, access issues, and security vulnerabilities within a connected SaaS or cloud environment. Content findings occur when CASB detects sensitive data at rest, such as exposed PII or developer code, by scanning stored files against data loss prevention (DLP) profiles.
Cloudflare CASB supports AI Security Posture Management (AI-SPM) by actively detecting GenAI-specific configuration risks across popular platforms like ChatGPT, Claude, Gemini, and Microsoft Copilot. This visibility ensures that employee usage of AI tools complies with corporate security policies and does not expose internal data.
Cloudflare CASB protects data at rest by securely connecting to cloud storage and SaaS APIs to scan for exposed files, misconfigured permissions, and code leaks. When a content finding is triggered, administrators can apply consistent DLP controls or initiate automated remediations directly from the dashboard.
Cloudflare CASB gives IT and security teams complete visibility into both sanctioned and unsanctioned SaaS, cloud, and AI application usage across their network. Once unsanctioned tools are discovered, administrators can review the findings and easily block risky apps using Gateway HTTP policies or redirect users to approved alternatives.
