Assuming the software is the same (usually isn't), virtual firewalls can be better than a physical firewall because you have better redundancy. A firewall is just a server with CPU, RAM, and uplink adapters. It's the same argument as a physical web server verses a virtual one.
Physical or Virtual Firewall: What fits best for your environment? However, some virtualisation software, such as a firewall, presents an attractive target to threat actors. If a hypervisor running security is attacked and breached hackers have an entry point to the business. Because a software firewall is running directly on a computer, it's in a position to know a lot more about network traffic than simply what port its using and where it's going -- it will also know what program is trying to access the Internet and whether it's legit or malicious (it consults a regularly updated database to determine this). A dedicated hardware firewall costs more than a software firewall, It is difficult to install , and upgrade , It takes up physical space , and involves wiring . The hardware firewalls tend to be more expensive than the software firewalls, When the hardware firewalls can not run on the computer, they can be a challenging to configure . Physical for Firewalls - always. Why? Cause as a software firewall, and this applies to "virtualized" instances - it can be compromised more easily. The OS layer is now an attack surface, the VM server is now an attack surface, the physical server ports (USB/serial/keyboard) are now an attack surface, etc. A software firewall can go in price from 'free' to $50, depending on the features and brand. Hardware vs Software Firewall. What's the difference between a hardware firewall and software firewall? It actually is vast and choice between the two will depend on the firewall's usage. A hardware firewall will have the better security, and is
Standalone physical firewall vs software based one - posted in Firewall Software and Hardware: Have to buy some firewall and Im divided between physical one (like one of Ciscos ASA family), or

In most hybrid environments, a combination of physical and virtualized firewalls will be deployed. The physical firewall segments between virtualized servers, so the right sets of users are accessing the virtualized servers. Meanwhile, the virtualized firewall delivers segmentation within the server, as shown in Figure 2.
A virtual firewall (VF) is a network firewall service or appliance running entirely within a virtualized environment and which provides the usual packet filtering and monitoring provided via a physical network firewall. The VF can be realized as a traditional software firewall on a guest virtual machine already running, a purpose-built virtual security appliance designed with virtual network Assuming the software is the same (usually isn't), virtual firewalls can be better than a physical firewall because you have better redundancy. A firewall is just a server with CPU, RAM, and uplink adapters. It's the same argument as a physical web server verses a virtual one. Hardware versus software. Contrary to a firewall, a data diode is a hardware product that enforces a one-way flow of data on the physical level. The diode device doesn't contain any software, logic or field-programmable gate arrays (FPGAs), and only has a physical path for signals to travel in one direction. Windows Firewall Control vs TinyWall - posted in Firewall Software and Hardware: Ive been using TinyWall for the past few days and I really like the simplicity and the lack of annoying pop-ups Hardware Firewall vs. Software Firewall With hackers, viruses, ransomware and malware compromising computer systems worldwide, every small business needs a hardware firewall. Firewalls provide enhanced IT security to protect your technology from attack, blocking unauthorized access while still allowing legitimate users access to the systems and
