amazon web services - How to whitelist VPC outbound traffic

Question

How can we restrict outbound traffic from AWS VPC to the internet, for example limiting outbound traffic to certain trusted domains (URL “whitelisting”). I was thinking on AWS WAF but it seems it filter trrafic traffic traveling to the web application not from web application. Any thoughts, suggestions, Thanks in advance.

It seems to be that you‘re looking for a proxy solution. As I know there aren‘t any managed proxy AWS services offered yet but you can use cloudformation, terraform or similar to setup it your own way with open source solutions f.e..

There is a good blog post on AWS about exactly your issue: https://aws.amazon.com/de/blogs/security/how-to-set-up-an-outbound-vpc-proxy-with-domain-whitelisting-and-content-filtering/
