AWS Shield Advanced cost: a flat subscription for DDoS protection

Quick answer

Shield Standard is free and protects all AWS customers against common DDoS attacks. Shield Advanced is a flat subscription of about $3,000/month (with a one-year commitment) that covers an entire organization, plus data-transfer-out charges for protected resources, and adds advanced mitigation, a response team, and cost protection against attack-driven scaling. It suits high-value, attack-prone applications where that protection justifies the fixed fee.

AWS Shield comes in two tiers. Standard is free and automatically protects every AWS customer against common, most-frequent DDoS attacks. Advanced is a paid subscription that adds sophisticated mitigation and support, and its flat monthly fee means the cost question is whether your risk justifies the subscription.

Standard is free; Advanced is a subscription

Tier	Cost	Provides
Shield Standard	Free	Automatic protection against common DDoS
Shield Advanced	~$3,000/month (1-year commit) + data transfer	Advanced mitigation, response team, cost protection

The Advanced subscription is roughly $3,000 per month, committed for a year, and covers all protected resources across an organization (not per-resource), plus data-transfer-out charges for the resources under protection. So the fixed fee is the same whether you protect one application or many.

What the subscription buys

Beyond stronger mitigation, Advanced includes access to the AWS Shield Response Team during attacks, detailed attack diagnostics, and cost protection, credits for the scaling costs a DDoS attack causes (extra data transfer, autoscaling), which can otherwise be substantial. That cost protection is part of the value: a large attack without it can generate a big surprise bill.

When Shield Advanced pays off

The flat fee is significant, so Advanced suits organizations with high-value, internet-facing, attack-prone applications where downtime or attack-driven cost would exceed the subscription. Because it covers the whole organization, the more protected resources you have, the better the fixed fee amortizes. For lower-risk workloads, free Shield Standard plus WAF is usually sufficient, the same enable-what-you- need discipline as any premium security tier.

FAQ

How much does AWS Shield Advanced cost?

A flat subscription of about $3,000 per month with a one-year commitment, covering an entire organization's protected resources (not per-resource), plus data-transfer-out charges for those resources. Shield Standard, which protects against common DDoS attacks, is free for all AWS customers.

When is Shield Advanced worth the cost?

For high-value, internet-facing, attack-prone applications where downtime or attack-driven cost would exceed the roughly $3,000 monthly subscription. Because it covers the whole organization, the more protected resources you have, the better the fixed fee amortizes. Lower-risk workloads are usually fine with free Shield Standard plus WAF.

What does Shield Advanced include beyond mitigation?

Access to the AWS Shield Response Team during attacks, detailed attack diagnostics, and cost protection, credits for the scaling costs a DDoS attack causes, such as extra data transfer and autoscaling. That cost protection is part of the value, since a large attack without it can generate a substantial surprise bill.

Do I need Shield Advanced or is Standard enough?

Shield Standard, which is free and automatic, protects against common DDoS attacks and suffices for most workloads. Shield Advanced adds sophisticated mitigation, a response team, and cost protection for high-value, attack-prone applications where the risk justifies the subscription. Pair Standard with WAF for application-layer protection.

Is Shield Advanced charged per resource?

No. The subscription is a flat organization-wide fee covering all protected resources, plus data-transfer-out charges for those resources. This means the fixed fee is the same whether you protect one application or many, so it amortizes better across more protected resources.

Does C3X estimate Shield cost?

Shield Advanced is a flat subscription plus data transfer for protected resources. C3X prices the surrounding infrastructure and data transfer from your Terraform; the subscription is a fixed organizational cost you weigh against your DDoS risk and the value of its cost protection.
