When to propose AWS Network Firewall vs 3rd party options?

Hi,

Can not speak for 3rd party firewalls but as far as AWS Network Firewall is concerned here is some useful information that you can go through:

• You can see the list of features supported here: AWS Network Firewall Features
• Compliance validation for Network Firewall
• Blog explaining Deployment models/design patterns
• If you want to try hands-on you can always try the workshop/lab
• AWS Network Firewall FAQs

Hope this helps
