Pod level external HTTP(S) proxy configuration with Istio
Companies frequently use proxies to act as a link between an internal network and the Internet. This is often frustrating for employees, even non-IT ones, when they can’t access a specific site from the company network. For engineers it’s even more obnoxious, since they have to configure all kinds of compute infrastructure to connect to external networks via these proxies.
It’s debatable if this is the best way to harden corporate network security, but it’s still the most widely spread method to restrict outgoing traffic.
