Preventing infrastructure abuse with Vercel Firewall

Vercel Firewall is an automatic security solution that blocks around 1 billion suspicious TCP connections per week and mitigates thousands of DDoS attacks daily to keep websites operational without user intervention. The firewall integrates Layer 4 protections with industry-leading third-party services, as well as proprietary Layer 7 protections tailored for modern web applications. It provides comprehensive, multi-layered security and a customizable Web Application Firewall (WAF) to protect against both infrastructure-level and application-level threats. This approach ensures that as attacks evolve, Vercel's protections can adapt to mitigate threats before they impact your applications.
