# Manage Vercel Firewall in the CLI

By Steven Van · 2026-05-12

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](<https://creatorstoolbox.com/tools/vercel>) CLI now has a [vercel firewall](<https://vercel.com/docs/cli/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.
