When Cloudflare AI Might Be Better
Cloudflare AI Prompt Protection excels in edge security scenarios:
- Existing Cloudflare customers: If you already use Cloudflare for CDN/WAF, AI protection integrates naturally
- Network-level enforcement: Block sensitive data at the edge before it reaches AI providers
- DLP policy enforcement: Centralized DLP policies across your organization's AI usage
- Block vs. transform approach: If you'd rather block sensitive data than transform and share it
Frequently Asked Questions
What's the difference between anonym.legal and Cloudflare AI Prompt Protection?

Can both prevent AI data leakage?
Yes, but differently. anonym.legal anonymizes data so you can safely share it while preserving utility. Cloudflare blocks data from being sent to AI providers. anonym.legal lets you still use AI; Cloudflare blocks usage.
