Create Vercel Firewall rules with natural language

Vercel introduced a natural language interface for creating Web Application Firewall (WAF) custom rules, allowing users to define firewall policies without writing complex rule syntax. This feature simplifies security configuration by enabling developers to describe their firewall requirements in plain English, which the system then converts into actionable WAF rules. This enhancement makes advanced security protection more accessible to users of varying technical expertise.
