Introduces the Vercel Web Application Firewall (WAF) as a new layer of defense against web threats. Key features include a customizable rules engine (path, user agent, IP, geolocation, JA4 fingerprints), framework-aware rules, managed rulesets for OWASP Top 10, observability into WAF metrics, rate limiting (beta), instant propagation (300ms), and instant rollback. The WAF leverages framework-defined infrastructure for intelligent edge request handling.
