Preventing infrastructure abuse with Vercel Firewall

Vercel describes its Firewall's multi-layered DDoS protection, which blocks around 1 billion suspicious TCP connections weekly and recently mitigated a 1.37 Tbps attack with no downtime.

The Firewall provides automated defense across all user tiers, integrating Layer 4 and Layer 7 protections, and includes a customizable WAF for application-level threats.
