This post introduces Vercel's defensive playbook against Denial of Wallet (DoW) attacks, which aim to drain a service's operational budget by exploiting cloud scalability. It details how Vercel uses rate limiting, its Web Application Firewall (WAF) with challenge-response protocols, spend controls and real-time monitoring, and multifaceted bot protection (behavioral analysis, challenge-based verification, adaptive filtering) to mitigate these threats. The post emphasizes Vercel's secure-by-default approach and how these features protect both infrastructure and budget.
