AWS Network Firewall

What AWS Network Firewall is
AWS Network Firewall is a managed cloud service for applying network protections across Amazon VPCs. Its stateful firewall inspects packets and supports rules based on IP addresses, ports, protocols, and traffic direction. Web controls include filtering HTTP headers, SNI, and domains, as well as an explicit forward proxy for outbound internet traffic. AWS-managed intrusion prevention signatures and malicious-domain rule groups are included at no additional cost. TLS inspection can analyze encrypted traffic within a VPC, though Advanced Inspection adds an hourly charge. Native integrations include Transit Gateway, VPC, IAM, and CloudWatch. AWS Firewall Manager can manage policies across accounts and VPCs; alert and flow logs can be stored in Amazon S3, Kinesis, or CloudWatch. The service scales capacity automatically and supports high availability across Availability Zones. AWS states a 99.99% uptime commitment under its service-level agreement. Pricing combines endpoint time and data processing, with rates varying by region and Availability Zone. AWS says the service is not designed to mitigate volumetric denial-of-service attacks.
Who it suits
It suits teams seeking to protect VPC boundaries, filter inbound and outbound traffic, or inspect traffic between VPCs. It is a cloud deployment, and AWS notes it is not designed for volumetric denial-of-service mitigation.
What it does well
- Supports deep packet inspection and traffic-direction rules.
- Includes AWS-managed intrusion prevention signatures at no additional cost.
- Firewall Manager can centrally manage policies across accounts and VPCs.
- Capacity scales automatically with high availability across Availability Zones.
- AWS states a 99.99% uptime commitment.
What to know first
- No free plan.
- Advanced Inspection adds an hourly charge.
- Marketplace managed rules may have seller-set fees.
- Not designed to mitigate volumetric denial-of-service attacks.
Limits
There is no free plan. Charges combine firewall endpoint time and per-GB traffic processing; Advanced Inspection and Marketplace managed rules can add fees, with rates varying by region and Availability Zone.
Plans
| Plan | Billed and limits | Price |
|---|---|---|
| Firewall endpoint | $0.395 for each hour the firewall endpoint is provisioned in US East (N. Virginia) · Managed firewall endpoint | $0.40 a month |
| Traffic processing | $0.065 for 1 GB of data processed in US East (N. Virginia) · Network Firewall data processing | $0.07 a month |
| Pay-as-you-go | Hourly per firewall endpoint, plus per-GB traffic processing; rates vary by region and Availability Zone. Pricing examples show $0.395 per endpoint-hour and $0.065 per GB. · Advanced inspection and active threat defense may add charges · AWS Marketplace managed rules may cost extra | On request |
