Apigee Collectors

Google Cloud Apigee is a fully managed API management platform that enables organizations to design, secure, analyze, and scale APIs.

AIDR integrates with Apigee through the open-source CrowdStrike AIDR shared flow bundle . The shared flow inspects both user prompts and LLM responses using the

AIDR APIs , enabling enforcement of security controls such as threat detection, PII redaction, and policy-based blocking without requiring changes to your application code.

The shared flow is deployed to an Apigee environment and invoked from your API proxy using FlowCallout policies .

Requirements

AIDR subscription with AIDR Admin assigned to your Falcon customer account
Google Cloud project with Apigee provisioned
An Apigee API proxy that serves LLM traffic in the Vertex AI generateContent format

Register Apigee collector

On the Collectors page, click + Collector.
Choose Gateway as the collector type, then select Apigee and click Next.
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.

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.

Deploy collector

Download and import shared flow

Download the latest release of the CrowdStrike AIDR shared flow from the GitHub releases page .
In the Google Cloud console, go to Apigee Shared flows .
Click Upload bundle and upload the downloaded shared flow archive.
Name the shared flow cs-aidr-guard.
Deploy the shared flow to the same Apigee environment as the API proxy you want to protect.

Create policies in your API proxy

In your API proxy, create the following three policies.

1. AssignMessage - Set AIDR configuration

The AM-SetAIDRConfig policy sets the AIDR API token and base URL as flow variables that the shared flow uses to communicate with AIDR APIs.

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

Example AM-SetAIDRConfig.xml
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<AssignMessage async="false" continueOnError="false" enabled="true" name="AM-SetAIDRConfig">
  <DisplayName>AM-SetAIDRConfig</DisplayName>
  <Properties/>
  <AssignVariable>
    <Name>cs_aidr_token</Name>
    <Value>pts_lj3nqp...6ssc3k</Value>
  </AssignVariable>
  <AssignVariable>
    <Name>aiguard_base_url</Name>
    <Value>api.crowdstrike.com/aidr/aiguard</Value>
  </AssignVariable>
  <IgnoreUnresolvedVariables>true</IgnoreUnresolvedVariables>
</AssignMessage>

cs_aidr_token - Your AIDR API token
aiguard_base_url - AIDR API endpoint for your region (without the https:// protocol prefix)

2. FlowCallout - Guard LLM input

The FC-LLMGuardInput policy invokes the shared flow to inspect the request before it reaches the LLM provider.

FC-LLMGuardInput.xml
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<FlowCallout async="false" continueOnError="false" enabled="true" name="FC-LLMGuardInput">
  <DisplayName>FC-LLMGuardInput</DisplayName>
  <Properties/>
  <SharedFlowBundle>cs-aidr-guard</SharedFlowBundle>
</FlowCallout>

3. FlowCallout - Guard LLM output

The FC-LLMGuardOutput policy invokes the shared flow to inspect the response from the LLM provider before it is returned to the client.

FC-LLMGuardOutput.xml
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<FlowCallout async="false" continueOnError="false" enabled="true" name="FC-LLMGuardOutput">
  <DisplayName>FC-LLMGuardOutput</DisplayName>
  <Properties/>
  <SharedFlowBundle>cs-aidr-guard</SharedFlowBundle>
</FlowCallout>

Attach policies to proxy flow

After creating the policies, attach them to your API proxy's flow:

Add AM-SetAIDRConfig and FC-LLMGuardInput to the request PreFlow - this runs AIDR input checks before forwarding the request to the LLM provider.
Add FC-LLMGuardOutput to the response PostFlow - this runs AIDR output checks on the LLM response before returning it to the client.

You can also use flow hooks to attach the shared flow at the environment level, applying it to all API proxies in that environment without modifying individual proxy configurations.

note:

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

Request PreFlow policies - Input Rules
Response PostFlow policies - Output Rules

Request schema

The shared flow expects API proxy requests and responses to follow the Vertex AI generateContent schema .

Ensure your API proxy handles requests in this format for the shared flow to correctly parse and inspect the content.

View collector data in AIDR

You can view the event data on the Findings page.

On the Visibility page, you can explore relationships between logged data attributes and view metrics in the AIDR dashboards.
