Examples of Hardware Firewalls

Most of the time, people use a hardware firewall without even realizing it. Too many hardware firewalls exist to name them all, but most of them use the same basic idea to protect Internet users from bad software. Hardware firewalls are a good way to protect your computer, but they work best when used with other security methods.

What Is Firewall Hardware?

A physical firewall device, also called firewall hardware, is an appliance that sits between the uplink and the client system and filters the traffic based on security policies, user profiles, and business rules that have already been set up. The uplink is where traffic from public or private networks comes in, while the client system can be a server, an employee’s desktop, a WFH system, an IoT node, etc.


CyberCoyote says that when people talk about hardware firewalls, they are really talking about routers, which are built-in firewalls. A computer that is connected to a router is given an IP address by the router, which uses its own IP address to direct traffic. So, it is much harder to target a specific computer that is behind a router than one that is connected directly.


All routers have hardware parts that act like firewalls. Linksys is a well-known company that makes routers. FirewallGuide says that there are, however, more expensive routers that are made by the same companies that make basic routers and have specific features to stop malicious users from attacking. True hardware firewalls, like the Linksys WRV200, use a method called “Stateful Pack Inspection” (SPI). SPI protection looks at the information that is being sent over the network to see if it contains any harmful code. Simple routers can only block certain ports and addresses.


Hardware firewalls are very good at keeping viruses and worms from infecting a single computer. CyberCoyote says that one problem with routers is that they make it easier for malicious software to spread to other computers on the network if one computer connected to them gets “malware” like a virus from a download than if they were on separate connections.


A wired or wireless router is a good example of a hardware firewall. However, FirewallGuide says that network administrators usually recommend a combination of a software firewall, anti-virus software, and a hardware firewall because other computers on the network are more likely to be vulnerable. When used together, software and hardware can make up for each other’s flaws and give the best protection all around.


Malware and viruses can get into a computer no matter what hardware or software is used to protect it. Hackers and other bad people are always coming up with new ways to break into a computer’s security system. As of 2009, people can put together a very safe computer security system for less than $200. This also needs the latest definitions and information from security vendors, which must be downloaded.

Different Hardware Firewall

A hardware firewall can be bought from many different places. The type of hardware and the company that makes it depend on what an organization needs.

Before deciding on a Firewall, there are a lot of things to think about.

  1. How well the computer network needs to be protected.
  2. The area where the company does business. For example, if it’s in the defense industry, it needs the most advanced Firewall to stop any leaks of data that could affect national security.
  3. The amount of money that can be spent on putting up the firewall.
  4. How many people are needed to keep the Firewall running.
  5. The reputation of the vendors for reliability and customer service after the sale.
  6. The ability to get updates often.

There are many kinds of hardware firewalls. Here is a list of the biggest and most popular companies that sell hardware firewalls to businesses that want to protect their data from being leaked or stolen.
