You can now receive alerts when the Vercel Firewall detects and automatically mitigates a DDoS attack on your Vercel project. With these alerts, you can get notified immediately when traffic to your application is blocked or challenged, so that you can review attack traffic and take any further action in a timely manner.

To get started, you can either set up a webhook to get notified through a defined HTTP endpoint, or use the Vercel Slack app to receive notifications in your Slack workspace.

These alerts are available on Pro and Enterprise plans.
