How to Set Up Cloudflare CASB with Claude Compliance API for Enterprise Agent Governance
Enterprise security teams finally have a native, agentless way to monitor what Claude is doing across their organization — and it doesn’t require touching endpoints, installing agents, or routing all traffic through a proxy.
On May 21, 2026, Cloudflare announced that its Cloud Access Security Broker (CASB) now supports Anthropic’s Claude Compliance API. The integration gives security and compliance teams out-of-band visibility into Claude Enterprise and Claude Platform activity, directly in the Cloudflare dashboard.
This is a meaningful step forward. Most organizations deploying Claude in production have had limited ability to answer basic governance questions: What files is Claude accessing? What projects contain sensitive data? Which API keys are being used? Who is doing what in which Claude workspace?
The Cloudflare CASB integration answers all of these questions — without requiring end-user behavior changes.
What the Integration Covers
The Cloudflare CASB integration with Claude Compliance API provides visibility into:
- Projects — what Claude projects exist in your organization, their contents, and who has access
- Chat files — files uploaded to Claude conversations across your tenant
- Messages and artifacts — the content of interactions flagged by DLP policies
- API key activity — which API keys are active, when they were last used, and associated usage patterns
This is out-of-band monitoring — meaning Cloudflare pulls this data via the Claude Compliance API, rather than sitting inline between users and Claude. There’s no endpoint agent required. No changes to how users access Claude. Security teams get visibility without user-facing friction.
For inline enforcement — blocking specific interactions in real time — you pair this CASB integration with Cloudflare Gateway. CASB provides the visibility layer; Gateway provides the enforcement layer when you need it.
Prerequisites
Before setting up the integration, you’ll need:
- A Cloudflare Zero Trust account with CASB enabled
- Claude Enterprise or Claude Platform access — the Compliance API requires an Enterprise or API-tier Anthropic account
- Access to the Claude Compliance API — documented at support.claude.com/en/articles/13015708-access-the-compliance-api
- Sufficient permissions in both Cloudflare (admin or security administrator role) and Anthropic’s admin console to generate compliance API credentials
Setting Up the Integration
The integration is configured through the Cloudflare Zero Trust dashboard’s CASB section. The general setup flow, as documented by Cloudflare:
Step 1: Generate Claude Compliance API credentials
In your Anthropic admin console, navigate to the Compliance API settings and generate the credentials needed for the Cloudflare integration. Anthropic’s compliance documentation provides the current steps for this — always refer to the official Anthropic Compliance API docs for the exact credential generation process, as the interface may evolve.
Step 2: Add a new CASB integration in Cloudflare
In the Cloudflare Zero Trust dashboard:
- Navigate to CASB → Integrations
- Select Add Integration
- Choose Anthropic Claude from the application list
- Enter the API credentials from Step 1
Cloudflare will validate the credentials and begin the initial data pull.
Step 3: Configure DLP policies
Once the integration is active, configure Data Loss Prevention (DLP) policies that apply to Claude activity. Cloudflare CASB supports DLP scanning across the data types listed above (projects, files, messages, artifacts).
For organizations with existing Cloudflare DLP profiles (for Google Workspace, Microsoft 365, Salesforce, etc.), you can apply the same detection patterns to Claude activity without creating new policies from scratch.
Step 4: Review findings in the Cloudflare dashboard
The Cloudflare dashboard surfaces:
- Policy matches — instances where Claude content matched your DLP rules
- Usage insights — overview of API key activity, project access patterns, and organizational Claude usage
- Alerts — configured notifications for high-severity policy violations
⚠️ Accuracy Note: The specific UI navigation paths and exact configuration steps above are based on Cloudflare’s May 21, 2026 announcement post (blog.cloudflare.com/casb-anthropic-integration/). Cloudflare updates its Zero Trust dashboard UI periodically. For the most current step-by-step guide, refer to the official Cloudflare CASB documentation at the time you configure the integration.
Pairing with Cloudflare Gateway for Enforcement
CASB gives you visibility. If you need to act on what you see — blocking specific Claude API interactions, enforcing geographic restrictions, or preventing file uploads that match DLP policies — you’ll use Cloudflare Gateway alongside CASB.
Gateway sits inline between your users (or agents) and the internet. When Cloudflare Gateway is deployed, it can:
- Block Claude API calls that violate policies
- Prevent file uploads to Claude that contain sensitive data patterns
- Enforce location-based restrictions on Claude access
The combination of CASB (visibility) + Gateway (enforcement) gives security teams the full governance stack for Claude usage in their organization.
For Gateway setup and integration with CASB findings, see the Cloudflare Gateway documentation.
Why This Matters for Agentic AI
Traditional CASB solutions were designed for human users accessing SaaS applications. The patterns are predictable: a user logs in, reads some files, maybe uploads a document.
AI agents break this model. An agent running on Claude might:
- Read thousands of documents in an automated pipeline
- Synthesize sensitive data from multiple data sources in a single response
- Generate artifacts that contain information the original authors never intended to aggregate
- Run 24/7 without a human in the loop to notice anomalous behavior
The Cloudflare CASB integration addresses agents as a first-class use case, not an afterthought. Out-of-band monitoring means the coverage extends to API-driven agent activity — not just users clicking around in the Claude web interface.
As AI agents become standard components of enterprise workflows, governance tooling needs to evolve with them. This integration is a practical step toward that — available today, with no endpoint changes required.
