Azure API Management Collectors

Azure API Management is a fully managed service that enables organizations to publish, secure, transform, maintain, and monitor APIs. It serves as a gateway between backend services and client applications, providing capabilities such as rate limiting, authentication, request/response transformation, and comprehensive analytics.

AIDR integrates with Azure API Management through custom policies that can inspect, validate, and secure traffic to and from upstream LLM providers using the

AIDR APIs .

This integration enables AI traffic visibility and enforcement of security controls - such as prompt injection detection, PII redaction, and malicious content blocking - without requiring changes to your application code.

Register Azure API Management collector

1. On the Collectors page, click + Collector.

2. Choose Gateway as the collector type, then select Azure API Management and click Next.

3. On the Add a Collector screen:

   • Collector Name - Enter a descriptive name for the collector to appear in dashboards and reports.
   • Logging - Select whether to log incoming (prompt) data and model responses, or only metadata submitted to AIDR.
   • Policy (optional) - Assign a policy to apply to incoming data and model responses.

   Use the assigned policy to determine which detections run on data sent to AIDR. Policies define rules for detecting malicious activity, sensitive data exposure, topic violations, and other risks in AI interactions.

   • You can select an existing policy available for this collector type or create new policies on the Policies page.

     The selected policy name appears under the dropdown. Once collector registration is saved, this label becomes a link to the corresponding policy page.

   • You can also select No Policy, Log Only. When no policy is assigned, activity is recorded for visibility and analysis without applying detection rules.

4. Click Save to complete collector registration.

This opens the collector details page, where you can:

• Copy credentials and AIDR base URL from the Config tab to communicate with AIDR APIs.
• View installation instructions for the collector type on the Install tab.
• Update the collector name, its logging preference, and reassign the policy.
• Follow the policy link to view the policy details.
• View the collector configuration activity logs.

If you need to return to the collector details page later, select your collector from the list on the Collectors page.

Set up Azure API Management

You'll need an existing Azure API Management instance and basic familiarity with Azure policies.

For detailed setup instructions, refer to the Azure API Management documentation .

Deploy collector

On the collector details page, you can switch to the Install tab for instructions on how to install and configure the AIDR policy in Azure API Management.

Configure named values

Before configuring the AIDR policy, you need to set up named values in Azure API Management to securely store your AIDR credentials.

1. In the Azure portal, navigate to your API Management instance.
2. Under APIs, select Named values.
3. Click + Add to create a new named value.
4. Create the following named values:

Name	Display Name	Type	Value	Description
ai-guard-url	ai-guard-url	Plain	Your AIDR endpoint URL	Example: https://api.crowdstrike.com/aidr/aiguard
ai-guard-token	ai-guard-token	Secret	Your AIDR API token	Keep this secure by selecting "Secret" type

You can copy both values from the collector's Config tab in the AIDR console.

note:

• ai-guard-url - This should be the full endpoint URL for your AIDR instance, including the protocol (https://).
• ai-guard-token - This should be your AIDR API token with appropriate permissions for AI Guard operations.

For more information on managing named values, see the Azure API Management named values documentation .

Install and configure AIDR policy

After setting up the named values, you can install and configure the AIDR policy in your Azure API Management instance.

1. Get the Policy XML: Copy the policy XML from the CrowdStrike AIDR Azure API Management repository .

2. Navigate to Policy Configuration:

   • In the Azure portal, go to your API Management instance.
   • Select APIs from the left menu.
   • Choose the API you want to protect.
   • Select All operations to apply to the entire API, or choose a specific operation.
   • In the Inbound processing section, select the </> (code editor) icon.

3. Apply the Policy:

   • Paste or merge the AIDR policy XML into your existing policy definition.
   • Ensure the named values ({{ai-guard-url}} and {{ai-guard-token}}) are correctly referenced.
   • Save the policy configuration.

Policy structure and requirements

The AIDR policy integrates into the standard Azure API Management policy sections:

<policies>
    <inbound>
        <base />
        <!-- AIDR policy for request inspection -->
    </inbound>
    <backend>
        <base />
    </backend>
    <outbound>
        <base />
        <!-- AIDR policy for response inspection -->
    </outbound>
    <on-error>
        <base />
    </on-error>
</policies>

Requirements:

• Your API must handle requests and responses in OpenAI API format.
• Named values for ai-guard-url and ai-guard-token must be configured.
• The policy validates and optionally transforms content before it reaches the LLM or is returned to the client.

note:

Policies are automatically associated with the collector's policy rules:

• Inbound policy - Input Rules
• Outbound policy - Output Rules

For detailed policy configuration options, refer to the Azure API Management policy documentation .
