Zscaler AI Guard provides AI-powered security for LLM applications. It enforces Detections Policies to perform security checks such as Data Loss Prevention (DLP) and prompt injection protection on both inbound prompts and outbound model responses.

Get Started with Zscaler AI Guard

Using Zscaler AI Guard with Prisma AIRS AI Gateway

1. Add Zscaler Credentials to the AI Gateway

  • Navigate to the Plugins page under Admin Settings
  • Click on the edit button for the Zscaler AI Guard integration
  • Add your Zscaler AI Guard API Key (the DAS Application Key generated from your Zscaler AI Guard tenant)

2. Add Zscaler AI Guard Check

  • Navigate to the Guardrails page and click the Create button
  • Search for “Zscaler AI Guard” and click Add
  • Configure your guardrail settings:
    • Policy ID: The ID of the Zscaler Detections Policy to execute (Required)
    • Timeout: The timeout in milliseconds for the scan (Default: 10000)
  • Set any actions you want on your check, and create the Guardrail!
Guardrail Actions allow you to orchestrate your guardrails logic. You can learn more about them here

3. Add Guardrail ID to a Config and Make Your Request

  • When you save a Guardrail, you’ll get an associated Guardrail ID - add this ID to the input_guardrails or output_guardrails params in your AI Gateway Config
  • Create these Configs in Strata Cloud Manager, save them, and get an associated Config ID to attach to your requests. More here.
Here’s an example config:
For more, refer to the Config documentation. Your requests are now guarded by Zscaler AI Guard, and you can see the verdict and any actions taken directly in your AI Gateway logs!
