Summary
Vercel added natural-language rule generation for Vercel Firewall custom rules. Users can describe the behavior they want in plain language and have the dashboard generate rate-limit, block, challenge, redirect, or logging rules, with a matching AI-assisted CLI flow exposed through vercel firewall rules add --ai.
What changed
Vercel enabled natural-language creation of WAF custom rules in the dashboard and CLI.
Why it matters
This lowers the barrier to shipping and iterating on web-application firewall policy, especially for teams that do not want to hand-author rule logic for every case. It also turns policy generation into an AI-assisted workflow rather than a purely manual security-admin task.
Evidence excerpt
Vercel says Firewall custom rules can now be created from natural language in the dashboard, and the CLI exposes the same flow with vercel firewall rules add --ai.
