Software Firewalls
A software firewall is installed on the host device. Accordingly, this type of firewall is also known as a Host Firewall. Since it is attached to a specific device, it has to utilize its resources to work. Therefore, it is inevitable for it to use up some of the system’s RAM and CPU.

If there are multiple devices, you need to install the software on each device. Since it needs to be compatible with the host, it requires individual configuration for each. Hence, the main disadvantage is the time and knowledge needed to administrate and manage firewalls for each device.
On the other hand, the advantage of software firewalls is that they can distinguish between programs while filtering incoming and outgoing traffic. Hence, they can deny access to one program while allowing access to another.
