Restrict access with IP blocking by CIDR range

Vercel Firewall protects your application from DDoS attacks and unauthorized access.

Enterprise teams now have increased security with the ability to control traffic and restrict access through static IP addresses or entire network CIDR ranges.

Stay secure by blocking entire subnets, or restricting access from untrusted networks, to prevent attacks against your applications.
