Manage Vercel Firewall in the CLI
By Steven Van ·
The new vercel firewall command covers custom rules, IP blocks, Attack Mode, and system mitigations, plus a skill for agents rolling out rules.
The Vercel CLI now has a vercel firewall command for managing a project's Firewall configuration from the terminal. It covers custom rules, IP blocks, system bypasses, Attack Mode, and system mitigations. Custom rule and IP block changes are staged as drafts until published; system bypass, attack challenge mode, and system mitigations apply immediately.
New rules can be created interactively, generated from a natural-language prompt with --ai, or defined with command-line flags or a JSON payload. A separate Vercel Firewall skill for coding agents documents best practices for rolling out new rules safely. Update the Vercel CLI and run vercel firewall to get started.
