It is like having a production line and have a product checked at the end of it.
There is no need to perform the same check multiple times if it is done properly the first time.
The difference nowadays between firewalls is basically the settings they allow the user to change and how easy it is to find them.
They just check where data is coming from and where it is trying to go to.
Having multiple firewalls only means you have to set them up all in the same way.
The only thing you achieve with having multiple firewalls is that you have more work setting them up.
Why blocking something with firewall-1 and setting firewall-2 to do the same thing?
The data traffic is already blocked in firewall-1 and doesn’t even reach firewall-2 !
And with software firewalls that means only wasting resources.
