When to Use Free AWS Shield and the Cost of Paid AWS Shield Advanced

AWS Shield is Amazon Web Services’ security solution designed to protect against DDoS (Distributed Denial of Service) attacks. It offers AWS Shield Standard for free and a paid version, AWS Shield Advanced, which provides enhanced security features. Since AWS Shield Advanced incurs additional costs, not all businesses require the paid version. This article explores when the free version suffices and outlines the costs associated with AWS Shield Advanced.

When AWS Shield Standard is Sufficient

AWS Shield Standard includes basic DDoS protection and is suitable for many use cases due to the following reasons:

1. Basic DDoS Attacks Are Mitigated by Standard

AWS Shield Standard automatically detects and mitigates DDoS attacks at the network (Layer 3) and transport (Layer 4) levels. Since most attacks fall within these categories, it is adequate for small- to medium-sized websites and online businesses.

2. Enhanced Protection Through AWS Service Integration

By combining AWS Shield Standard with services like Amazon CloudFront and AWS Global Accelerator, you can create a stronger defense without incurring additional costs. This combination is particularly effective for small businesses that prioritize cost efficiency.

3. Low-Risk Applications

Some businesses and services have a lower likelihood of being targeted by attacks. For example:

• Internal systems with limited access.
• Low-traffic websites with minimal exposure.

For such cases, the free Shield Standard provides sufficient protection without over-investing in additional security.

4. Cost-Conscious Operations

Startups and small businesses often operate on limited budgets. Shield Standard offers foundational DDoS protection at no cost, allowing businesses to secure their environments while focusing their budgets on growth.

Costs of AWS Shield Advanced

AWS Shield Advanced delivers more robust DDoS protection and incident response features, but it comes with associated costs:

1. Base Monthly Fee

• AWS Shield Advanced costs approximately $3,000 per month as a base fee.
• This includes access to advanced mitigation capabilities and support features.

2. Additional Fees Based on Data Transfer

• The cost of Shield Advanced also depends on the data transfer associated with AWS services like Amazon CloudFront, Elastic Load Balancing, Route 53, and AWS Global Accelerator.
• Businesses with significant traffic should account for additional data transfer fees on top of the base cost.

3. Cost Protection and Incident Support

• Shield Advanced includes cost protection for unexpected AWS resource usage caused by DDoS attacks. For example, any increased expenses due to mitigating an attack can be reimbursed under the plan.
• Customers also gain access to the DDoS Response Team (DRT), a 24/7 incident response team, ensuring quick resolution and minimal downtime during an attack.
