Differences between a hardware and software firewall

A firewall is one more option that allows us protect our systems. We can say that it is a barrier between our device and the network. It allows analyzing the connections and determining when there may be an insecure person that puts a computer, mobile or any equipment at risk. In case there is any risk, it blocks it.

We can configure different aspects, such as creating a white list that allows certain connections, blocking programs so that they cannot access the Internet, ports, etc. We normally use a software firewall, which is basically a computer program that we install. There are free ones, such as the Windows firewall itself, but we have a wide range of options.

But also, we can also count on a hardware firewall It is one more option that we can take into account to protect systems and avoid problems on the network. But what are their differences?

Structure

The first clear difference is that a software firewall is a program, somewhat intangible, while a hardware firewall is a physical device. Although they have the same objective of controlling connections, there is a differential point in their structure. An application is not the same as a computer equipment.

It is similar to when we see a physical VPN and another at the application level. In the case of software we will be able to install it on the system, while a hardware firewall will be a device independent of our computer.

Ease of use

This question is important for domestic user. Is it easier to use a hardware or software firewall? It is certainly a key factor in choosing one or the other option in most cases. Here the difference is clear and it will be much easier to use a program firewall.

In the case of software we will only have to install it on the system. Some even do not require configuration or this is minimal, since it comes preconfigured with the most basic to protect connections. On the other hand, if you use a hardware firewall it will require physical installation and greater configuration. It is more geared towards more experienced users.

Security

Clearly security is one of the reasons why we use a firewall. We want to keep protection to the maximum and not have problems with malware or attacks that may compromise our systems. But which of the two options is safer for our systems?

It should be noted that the two of us will protect ourselves, as long as we use a correct option. That is, not all firewalls will protect the same, in the same way that not all antiviruses protect us well, etc. However, a program firewall will receive updates more frequently and that gives it a plus. Instead, a hardware firewall will protect the connection that enters a computer, no matter what operating system we are currently using.

Usability

There are also differences in usability. We can install a software firewall on our computer or mobile, making it a program that will remain there. If we take that equipment and move to another place and connect to another network, it will still protect us.

Instead, a physical firewall is normal for it to be connected to the router. It will be less flexible to be able to move it from one place to another. Therefore, at the home user level, the most useful thing is software and not a physical device.

Price

As for prices we will find clear differences. A software firewall can be free, such as Microsoft itself or many other options found on the Internet, or at a low cost. On the other hand, a hardware firewall is going to be more expensive and it is an investment that we will have to make.

Therefore, if you are looking to protect your equipment and do not want to make a financial outlay, the best option is undoubtedly a program firewall. You are going to avoid having to buy a device, so that can mean in terms of price.

Which to choose

After explaining the main differences between a software and hardware firewall, let's talk about when to use one or the other option. In this way you can choose which one suits you best depending on the use you are going to give it and how you want to protect your devices.

Protect a device or many

The first thing you should think about is what are you going to protect. A single device, such as a computer or mobile, is not the same as an entire network, to which you will be able to connect many devices of all kinds. This will be key to choosing what is best for you and acquiring a physical device or program

If you are only going to protect a computer, such as a computer, it is better for you to use a software firewall. On the other hand, if you want to protect an entire network, the ideal is for you to use a hardware firewall. In this way you will protect everything you connect to your network.

Domestic user or company

But if there is a clear reason to choose one option or another, it is to see if you are going to use it to domestic level or for a company. Normally, to use it personally, to protect a computer or mobile, it is best to use a program firewall. You will not require more than that and so you do not have to spend anything or very little.

If you want protect a company, where there are going to be many devices of all kinds connected, in that case it may be interesting to use a physical firewall. This is what will allow blocking malicious connections for the entire network and thus avoid problems that affect essential components of an organization.

Where are you going to use it

The place where you will need it It will also be a key factor in choosing one or the other option. If you are going to use a computer on different networks, such as at home, at work, in a library, on the go… Undoubtedly, the ideal is to have a firewall at the software level, since you will be able to take it anywhere.

On the other hand, if you are going to use it only in your home, work or any fixed site, then you might be interested in a hardware firewall. In that case you will not be able to move it, but you would not have a need for it either.

In short, as you have seen you have the option of using a software or hardware firewall. They are two different options, but they have the same objective: to protect your connections and prevent threats to your network and your devices. Depending on the case, it may be better for you to use one or the other option.
