How It Works

This workflow automates Identity and Access Management (IAM) event governance using an AI agent, targeting security operations teams, compliance officers, and IT governance teams managing cloud or enterprise IAM systems. The core problem it solves is the manual, error-prone review of IAM events, such as permission grants, role changes, and access revocations, which are high-risk and require rapid, consistent decision-making at scale. When an IAM event is received via webhook (POST), a Governance Agent powered by an LLM evaluates it using contextual memory, an Access Signal Agent, and a forgeLLM API. It cross-references compliance rules via a Compliance Query Tool and logs findings through an Audit Log Tool. Notifications are dispatched via Email and Slack. Based on the agent's decision, a Rules-based Router directs the event into one of three branches, namely: Approved, Revoked, or Escalated, where event data is prepared and stored accordingly. A unified response is then returned to the caller, ensuring every IAM event is audited, classified, and actioned without human bottlenecks.

Setup Steps

  1. Configure the Webhook node with your IAM event source endpoint.
  2. Add LLM credentials to the forgeLLM API Tool node.
  3. Set up Governance Model with your policy prompt and connect Conversation Memory.
  4. Configure Access Signal Agent with your access data source credentials.
  5. Connect Compliance Query Tool to your compliance database or API.
  6. Add Gmail/SMTP credentials to the Email Notification Tool.
  7. Add Slack Bot token to the Slack Notification Tool.

Prerequisites

  • forgeLLM or compatible LLM API key
  • Slack Bot token
  • Gmail/SMTP credentials

Use Cases

  • Automatically approve or revoke IAM role assignments based on policy.

Customization

  • Swap forgeLLM for OpenAI or Anthropic models.

Benefits

  • Eliminates manual IAM review bottlenecks.

4. Reproducing the Workflow from Scratch

  1. 1. Download the workflow JSON

    Use the JSON export at /data/workflows/14409/14409.json as the source template for this automation.

  2. 2. Import the template into n8n

    Open n8n, import the downloaded JSON, and review each node before activating the workflow.

  3. 3. Configure credentials and variables

    Replace placeholder credentials, API keys, webhook URLs, account IDs, and environment-specific values with your own settings.

  4. 4. Test with sample data

    Run the workflow manually or in a staging workspace, inspect node output, and confirm downstream systems receive the expected data.

  5. 5. Activate and monitor

    Enable the workflow only after testing, then monitor executions, errors, and rate limits during the first production runs.

5. General Notes & Resources

Review imported nodes carefully before activation. This catalog entry is intended to help you inspect the workflow structure, understand required services, and find related templates faster.

Node names, credentials, schedules, webhook paths, and external service limits may need adjustment for your workspace.
