Updated on 28 August, 2025

Distributed Denial of Service (DDoS) protection enables traffic monitoring and prevents potential DDoS attacks to an instance. It activates a set of tools that detect and block network flooding attempts, ensuring the instance remains active and operational.

Follow this guide to enable DDoS protection on a Vultr Cloud Compute instance using the Vultr Customer Portal, or Terraform.

  • Vultr Customer Portal
  • Terraform
  1. Navigate to Products and click Compute.
  2. Click your target Vultr Cloud Compute instance to open its management page.
  3. Navigate to the DDoS tab.
  4. Click Enable DDoS Protection.
  5. Click Enable DDoS Protection in the confirmation prompt to enable DDoS protection on your instance.

  1. Open your Terraform configuration for the existing Cloud Compute instance.

  2. Enable DDoS protection in the instance resource.

    terraform 
    resource "vultr_instance" "cc" {
    # ...existing fields (region, plan, os_id, label, etc.)

    ddos_protection = true
}

  3. Apply the configuration and observe the following output:

    Apply complete! Resources: 0 added, 1 changed, 0 destroyed.
