AWS Shield

AWS Shield is AWS’s DDoS defense and network-security analysis service for customers protecting websites and applications on AWS. It suits teams running internet-facing workloads on eligible AWS resources; Standard is a baseline, while Advanced is for those who need application-layer mitigation and operational protections.

Overview

Shield Standard is automatically configured for AWS customers and protects against common network- and transport-layer DDoS attacks. That makes it a useful baseline for AWS workloads, but it does not provide the broader mitigation and monitoring offered by Advanced. Advanced detects sophisticated events across network, transport, and application layers and can block them with automatic inline mitigation.

Network Security Director analyzes AWS resources, maps network topology, identifies configuration issues, and recommends remediation. It is in preview and is not included in either Shield plan, so it should be viewed as a separate analysis capability rather than a plan benefit.

Key features

Detection and mitigation

Advanced establishes application traffic baselines to identify anomalies such as HTTP floods and DNS query floods, then applies automatic mitigation. This combination is useful for internet-facing applications where attacks may target more than the network or transport layers. Standard's narrower coverage remains relevant for customers who need common DDoS protection without an Advanced subscription.

AWS integrations and support

Advanced can protect EC2, Elastic Load Balancing, CloudFront, Global Accelerator, and Route 53 resources. It integrates with AWS WAF and AWS Firewall Manager, with event visibility through Amazon CloudWatch. Its subscription includes up to 50 billion AWS WAF requests per subscribed payer account per calendar month for protected resources, a meaningful allowance for high-volume workloads, though usage fees may still apply.

Advanced includes DDoS cost protection for qualifying usage spikes on protected resources. The Shield Response Team is available 24/7 to Business or Enterprise support customers; custom mitigations during events also require one of those support plans. That makes the response offering less complete for customers without the qualifying support tier.

Pricing

Advanced is billed as a monthly fee but requires a 1-year subscription commitment and renews annually; usage fees may apply. The commitment and $3,000.00 monthly price make it a targeted choice for AWS customers whose protected workloads justify the added defenses, rather than a routine upgrade for every account. Standard costs nothing, but gives up application-layer mitigation, traffic monitoring, cost protection, and the Advanced WAF allowance.

Platforms

Shield is available through API and web access. Its deployment model is cloud-based, and its protections are intended for AWS resources rather than a general cross-cloud security setup.

Who it's for

Choose Shield if your websites or applications run on AWS and you want DDoS protection aligned with AWS services. Advanced is most relevant to teams protecting internet-facing applications on its eligible resources, particularly when application-layer mitigation, traffic visibility, and qualifying cost protection matter. If the need is limited to baseline network and transport protection, Standard is the more proportionate choice.

Pros and cons

• Pro: Standard is automatically configured for AWS customers and has no charge, providing a baseline without a paid subscription.
• Pro: Advanced combines mitigation across three attack layers with traffic anomaly monitoring and AWS service integrations.
• Pro: The WAF request allowance and DDoS cost protection add practical benefits for qualifying protected workloads.
• Con: Advanced costs $3,000 a month and binds subscribers to a one-year commitment with annual renewal.
• Con: Shield Response Team access and custom event mitigations depend on Business or Enterprise support.
• Con: Network Security Director is in preview and is not part of either Shield plan.

Alternatives

DDoS Protection Software is a useful starting point if you want to compare options by category rather than choose an AWS-specific service immediately.

• Cloudflare DDoS Protection is worth considering if its free plan, which includes unmetered DDoS protection and a WAF, better matches your needs; its Pro plan is $20 a month billed annually.
• Gcore DDoS Protection may suit readers seeking a freemium option with a PAYG plan at no cost and a Start plan at $275 a month.
• Fastly Image Optimizer is an alternative for readers focused on image optimization, with a free allowance of 100,000 image requests per month.
• F5 BIG-IP APM is another option, with a free trial and a perpetual license for BIG-IP Virtual Editions, hardware, or hybrid environments.
• Haltdos offers a Community WAF plan at no cost for one website and one security profile, as well as a Professional WAF plan at $30 a month.
• Oracle Cloud Infrastructure Secret Management is a free alternative for readers looking for secret management rather than DDoS protection.
• Tencent Cloud API Gateway may fit readers looking for an API gateway, with the first 1 million API calls per month free during the first year on its shared instance.
• FastNetMon is another alternative to consider.

Verdict

AWS Shield is the right choice for AWS customers who want DDoS defense tied to their AWS workloads. Standard offers a no-charge baseline, while Advanced is compelling when application-layer mitigation, monitoring, and protection for eligible resources justify its high monthly fee and annual commitment. Look elsewhere if you need a different kind of security product or cannot justify that commitment.
