## New DLP topic based detection entries for AI prompt protection

You now have access to a comprehensive suite of capabilities to secure your organization's use of generative AI. AI prompt protection introduces four key features that work together to provide deep visibility and granular control.

1. **Prompt Detection for AI Applications**

DLP can now natively detect and inspect user prompts submitted to popular AI applications, including **Google Gemini**, **ChatGPT**, **Claude**, and **Perplexity**.

2. **Prompt Analysis and Topic Classification**

Our DLP engine performs deep analysis on each prompt, applying [topic classification](https://developers.cloudflare.com/cloudflare-one/data-loss-prevention/detection-entries/configure-detection-entries/#ai-prompt-topics). These topics are grouped into two evaluation categories:

- **Content:** PII, Source Code, Credentials and Secrets, Financial Information, and Customer Data.
- **Intent:** Jailbreak attempts, requests for malicious code, or attempts to extract PII.

To help you apply these topics quickly, we have also released five new predefined profiles (for example, AI Prompt: AI Security, AI Prompt: PII) that bundle these new topics.

3. **Granular Guardrails**

   You can now build guardrails using Gateway HTTP policies with [application granular controls](https://developers.cloudflare.com/cloudflare-one/traffic-controls/http-policies/#granular-controls). Apply a DLP profile containing an [AI prompt topic detection](https://developers.cloudflare.com/cloudflare-one/data-loss-prevention/detection-entries/configure-detection-entries/#ai-prompt-topics) to individual AI applications (for example, `ChatGPT`) and specific user actions (for example, `SendPrompt`) to block sensitive prompts.![DLP](https://developers.cloudflare.com/cdn-cgi/image/onerror=redirect,width=731,height=511,format=webp/_astro/ai-prompt-policy.CF3H2rbK.png)
4. **Full Prompt Logging**

   To aid in incident investigation, an optional setting in your Gateway policy allows you to [capture prompt logs](https://developers.cloudflare.com/cloudflare-one/data-loss-prevention/dlp-policies/logging-options/#log-generative-ai-prompt-content) to store the full interaction of prompts that trigger a policy match. To make investigations easier, logs can be filtered by `conversation_id`, allowing you to reconstruct the full context of an interaction that led to a policy violation.![DLP](https://developers.cloudflare.com/cdn-cgi/image/onerror=redirect,width=728,height=444,format=webp/_astro/ai-prompt-log.ywQDc5qN.png)

AI prompt protection is now available in open beta.
