What is the Vercel Firewall?

Can somebody be so awesome to explain what is the Vercel firewall and what does it do exactly?

I noticed this a while back

The Vercel Firewall protects apps and sites against attacks and unauthorized access. It’s made up of a platform-wide firewall with DDoS mitigation and Web Application Firewall (WAF) with customizable rules and Attack Challenge Mode.

You can read all about it here: Vercel Firewall :slightly_smiling_face:

We also organised this Vercel Community Session which may be helpful :sparkles:
