Security through design: Creating the improved Firewall experience

What this post added

The post details a redesign of the Vercel Firewall user interface to improve usability and provide better visibility into security events. Key improvements include a redesigned overview page with alerts, rules, events, and denied IPs feeds; a new traffic page with comprehensive intelligence on IPs, JA4 digests, AS names, user agents, request paths, and rules with most activity; dedicated tabs for Firewall Rules and Audit Log; and faster event inspection with a detailed view directly within the page. While the post focuses on UI/UX improvements for security tooling, it implies underlying system enhancements to provide this richer data and faster inspection, potentially related to how traffic data is processed and presented. However, it does not introduce new core system capabilities like sharding or Bloom filters for redirects, but rather enhances the user's interaction with existing security systems.
