AWS Network Firewall Pricing Updates: Ultimate Guide

Introduction¶

AWS Network Firewall is an essential tool for organizations looking to secure their cloud infrastructure. Recently, AWS has announced significant price reductions that make network security even more accessible. In this comprehensive guide on AWS Network Firewall pricing updates, we will explore the new cost-saving measures, delve into the functionalities offered by AWS Network Firewall, and provide actionable insights on maximizing these improvements. Whether you are a beginner or an expert in cloud security, this article will provide you with valuable information to optimize your network firewall practices.

What Are the New Pricing Improvements?¶

AWS Network Firewall has introduced two major pricing enhancements aimed at reducing costs for customers. These are:

NAT Gateway Discounts: Discounts have been extended to include secondary Network Firewall endpoints, allowing service chaining.
Removal of Advanced Inspection Charges: The additional data processing charges for TLS inspection have been eliminated for specific AWS regions.

Understanding the Impact of These Changes¶

The earlier restrictions meant that NAT Gateway discounts only applied when traffic was processed by primary Network Firewall endpoints. Furthermore, advanced TLS inspection came with a varying cost that could impact budgeting for cybersecurity solutions. The removal of these charges and the extension of discounts offers organizations the opportunity to save considerably while enhancing their security frameworks.
