Vercel WAF upgrade brings persistent actions, rate limiting, and API control

Vercel has introduced new capabilities for its Web Application Firewall (WAF), including persistent actions, rate limiting, and a Firewall API. These enhancements aim to reduce the effects of DDoS attacks and improve traffic control. Persistent actions allow rules to be applied across all matching requests for a customizable duration, while rate limiting sets request limits on specific endpoints to prevent abuse. The Firewall API enables programmatic control over WAF settings, allowing for automation and integration with third-party tools. These improvements enable Vercel customers to better serve desired traffic while taking action against malicious behavior.
