aws_shield_protection cost estimation

An aws_shield_protection enrolls a specific resource (an ALB, CloudFront distribution, Global Accelerator, Elastic IP, or Route 53 hosted zone) in AWS Shield Advanced, managed DDoS protection with 24/7 response team access, cost-protection guarantees against DDoS-driven scaling, and detailed attack diagnostics.

The crucial cost fact: Shield Advanced is a flat ~$3,000/month subscription, committed for one year, and that single fee covers the whole organization, protecting one resource or a hundred costs the same. There's also a data-transfer-out fee for protected resources, but the $3,000 subscription dominates and is the decision point.

Because the subscription is org-wide and flat, the cost question is binary: does your organization need Shield Advanced at all? It's justified for businesses where DDoS downtime is genuinely costly and the response-team access and cost-protection guarantee matter. Most workloads are adequately served by Shield Standard (free, automatic) plus WAF. Once you do subscribe, enroll every resource that warrants protection, the fee is already paid.

c3x prices Shield Advanced as the flat monthly subscription, so this substantial standing cost is visible, and counted once, not per protected resource.

Terraform example

A minimal but realistic configuration that C3X can estimate.

resource "aws_shield_protection" "alb" {
  name         = "prod-alb-protection"
  resource_arn = aws_lb.main.arn

  tags = {
    Environment = "production"
  }
}

Optimization tips

Common ways to reduce aws_shield_protection cost without changing the workload.

Decide at the organization level, it's one flat fee

The entire fee if Standard suffices

Shield Advanced is ~$3,000/month for the whole organization regardless of how many resources you protect. The decision is whether your business needs it at all; if so, the fee is fixed, so protect everything that warrants it.

Use Shield Standard + WAF for most workloads

$3,000/month when Standard is enough

Shield Standard is free and automatic, covering common network/transport-layer attacks; pairing it with WAF handles application-layer protection. Most workloads don't need Advanced's ~$3,000/month subscription.

Enroll all warranted resources once subscribed

Maximizes value of the fixed fee

Since the subscription is already paid org-wide, enroll every resource that benefits (ALBs, CloudFront, Global Accelerator, EIPs, Route 53), there's no per-resource subscription cost, only the shared fee.
