Why Audit Log Drains Matter for Enterprise Teams

If you're running a production app on Vercel, your team's activity log is a goldmine of security and compliance data. Every deploy, configuration change, and team member action leaves a trace. But unless you're actively monitoring those logs, you're flying blind.

Vercel's Audit Log Drains have been a crucial feature for enterprises that need to centralize their audit trails. Now, with the addition of Datadog, Splunk, and Panther as destinations, you can stream your team's audit events directly into the SIEM tools you already use. This is a significant upgrade for teams that rely on these platforms for real-time threat detection and incident response.

What Are Audit Log Drains?

An Audit Log Drain forwards every event from your team's Activity Log—plus additional audit metadata—to a destination of your choice. This ensures that you have a complete, tamper-proof record of who did what, when, and where. For enterprises that need to meet SOC 2, ISO 27001, or other compliance standards, this level of visibility is non-negotiable.

Previously, you could only send audit logs to a custom HTTPS endpoint or Amazon S3. Now, with native integrations for Datadog, Splunk, and Panther, you can skip the middleman and get your logs into your SIEM of choice with just a few clicks.

How to Set Up an Audit Log Drain

Setting up an Audit Log Drain is straightforward. Here's a step-by-step guide:

  1. Navigate to your team settings on Vercel.
  2. Go to Drains.
  3. Click Add Drain.
  4. Choose Audit Log as the data type.
  5. Select your destination: Datadog, Splunk, Panther, or the existing custom HTTPS endpoint / Amazon S3.

Below is a simplified example of how to configure an Audit Log Drain using Vercel's API (for demonstration purposes):

# Create a new Audit Log Drain to Datadog
curl -X POST "https://api.vercel.com/v1/drains" \
  -H "Authorization: Bearer $VERCEL_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "type": "audit-log",
    "destination": "datadog",
    "config": {
      "api_key": "your-datadog-api-key",
      "site": "datadoghq.com"
    }
  }'

Note: This is a simplified example. Always refer to Vercel's official API documentation for the most up-to-date payload structure.

Migration from Custom SIEM Log Streaming

If you were previously using Custom SIEM Log Streaming, you'll need to migrate to the new Audit Log Drains. Vercel provides a migration guide to help you transition seamlessly. The new system is more robust and offers better integration with enterprise-grade SIEM tools.

Limitations and Considerations

While the new Audit Log Drains are a welcome addition, there are a few caveats to keep in mind:

  • Enterprise plan only: This feature is exclusive to Vercel's Enterprise tier. If you're on a Pro plan, you won't have access.
  • No real-time streaming: While the logs are forwarded quickly, there may be a slight delay. For real-time security monitoring, ensure your SIEM can handle a few seconds of latency.
  • Data volume: Audit logs can generate a lot of data, especially in large teams. Be mindful of your SIEM's ingestion limits and associated costs.

Next Steps for Implementation

Now that you know the basics, here's how to move forward:

  1. Map out your audit log needs: Identify which team members and actions generate the most critical audit events.
  2. Set up your drain: Use Vercel's UI or API to create a drain for your preferred SIEM.
  3. Test thoroughly: Send a few test events and verify they appear in your SIEM correctly.
  4. Set up alerts: Leverage your SIEM's alerting capabilities to get notified of suspicious activities.

Conclusion

Vercel's expansion of Audit Log Drains to Datadog, Splunk, and Panther is a game-changer for enterprise teams that need robust security and compliance monitoring. By streamlining the integration process, Vercel is making it easier than ever to keep a close eye on your development pipeline.

For teams already using these SIEM tools, the migration path is clear. If you're just starting, now is the perfect time to implement audit log streaming to strengthen your security posture.
