Do you need 2 firewalls for a DMZ?

The more secure approach to creating a DMZ network is a dual-firewall configuration, in which two firewalls are deployed with the DMZ network positioned between them. The dual-firewall approach is considered more secure because two devices must be compromised before an attacker can access the internal LAN.

What is a two way firewall?

Microsoft describes the firewall as “two-way” because it filters both incoming and outgoing network traffic, meaning it can be used to block machines attempting to connect to the Windows PC as well as applications on the PC trying to connect to other systems on the network.
