The Vercel Terraform Provider now allows you to customize and control the Vercel Firewall through Infrastructure as Code (IaC).

Key resources and their capabilities include:

• Resource: vercel_attack_challenge_mode

• Resource: vercel_firewall_config

  • Attribute block: rules—Define and adjust custom rules.

  • Attribute block: ip_rules—Manage a list of blocked IP addresses.

For example, to create a new rule that challenges requests where the user_agent contains curl:

resource "vercel_firewall_config" "example" {
  project_id = vercel_project.example.id
  rules {
    rule {
      name = "Challenge curl"
      description = "Challenge user agents containing 'curl'"
      condition_group = [{
        conditions = [{
          type = "user_agent"
          op = "sub"
          value = "curl"
        }]
      }]
      action = {
        action = "challenge"
      }
    }
  }  
}
