Updated on 28 August, 2025

Distributed Denial of Service (DDoS) protection enables traffic monitoring and prevents potential DDoS attacks from overwhelming an instance. DDoS protection actives a set of tools that block network flooding attempts targeting an instance.

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

  • Vultr Customer Portal
  • Terraform
  1. Navigate to Products and click Compute.
  2. Click your target 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 the instance.

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

  2. Update the ddos_protection value in the instance resource to true.

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

    ddos_protection = true
}

  3. Apply the configuration and observe the following output:

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