Best Hardware Firewalls for Home and Small Business Networks

A hardware firewall is a physical apparatus or device that is used to protect and monitor a network. All of the network links and as well as the traffic coming in and out of this boundary will need to pass through the firewall, which puts it in the position to inspect all incoming and outgoing traffic over the network and make sure that policies are set in place are keeping things secure.

Without having security at a border, anyone and everyone will be able to breach and do whatever they like. Computer networks work in a sort of the same way. You need to put in place proper security measures and ensure that the traffic both inbound and outbound is legitimate and free from any sort of malicious intent.

These days with the growing threats that individuals have on the internet, it is safe to say that having some form of protection over the network is key to online security. Firewalls are a relatively cheap solution that provides security without necessarily having to invest a huge deal in infrastructure.

Businesses like individuals are at the forefront of online threats and at the mercy of hackers. To prevent loss to the business and to protect the interest of their customers having sound online security is key. The right hardware firewalls for a small business network will take into consideration things like the size of the business, its security needs as well as the budget.

What are the Best Hardware Firewalls for Home Network Use?

The last thing that someone working remotely from home or even an average user would want is for their password to be compromised leaving them exposed to a hacking attempt, or all sorts of malicious software making their way to their devices. Despite taking all sorts of precautions, hackers can still gain access to your network and infect your devices.

It can be nerve-wracking for an average user to worry about potential data breaches and how a cyber attack or any sort of malware can affect an entire household. But thankfully, firewalls designed for the home provide a simple plug-and-play alternative.

People can buy hardware firewalls for their homes that will at least give them a baseline of security that they can rely on. The thing about hardware firewalls is that they are easy to use and a lot of them have limited installation steps and configuration details. This also allows the average user to get a better idea of the device they are using as well as utilize a firewall device without paying for installation fees.

Here are some of the best hardware firewalls that you can use for your home network:

1. pfSense SG-2100

The SG-2100 is a security gateway appliance that is coupled with pfSense software® to provide relatively decent functionality and performance for its size and class.

Performance-wise the SG-2100 with pfSense has a 2.20 Gbps router, 964 Mbps firewall, and a 254 Mbps IPsec VPN. These are respectable performance results given that the device is compact and easy to store away. It also has an attractive GUI that you can use to configure the device and set it according to your liking.

The pfSense SG-2100 from Netgate costs around $350 and you can purchase an extended warranty as per your need.

By easily installing and configuring Zenarmor on your pfSense hardware firewall, you have a powerful next-generation firewall to protect your home network against cyber threats. pfSense powered with Zenarmor offers home users enterprise level protection features like web filtering, application control and cloud threat intelligence.

2. WatchGuard Firebox Model T15

The WatchGuard Firebox T15 is a brilliant solution that is designed to take on the needs of large-scale organizations or if the need arises, to take care of remote workers at home. The T series from WatchGuard is designed to manage things in a centralized manner, giving you full control of how you are going to use the device and the sort of security you want to enable.

The good thing about the WatchGuard Firebox T15 is that it can easily be deployed anywhere that a network is connected and provides much-needed surveillance and security. The device can also be connected to the cloud which means that you can securely download the configuration settings and set up the device yourself without needing trained staff or outsourcing this task to an external vendor.

In terms of performance, you can expect a 120Mbps Firewall and a 46 Mbps VPN. These are very good performance metrics since the device is relatively affordable and is compact at the same time. You can also use the WatchGuard Firebox T15 as you scale and grow your usage at home.

A new device costs around $400 which is a bit more expensive than previous entries on this list. But given how the device has a lot of functionality and convenience to offer, the tradeoff can be justified for an appropriate use case.

3. Bitdefender BOX

You can think of the Bitdefender BOX as an enhanced router that can be used in place or be used with your present home networking setup. You can connect your devices to the BOX and it acts as a firewall, which helps to monitor inbound connections as well as ward off any hackers that are in search of an unprepared user.

4. Mikrotik hEX RB750Gr3

The Mikrotik hEX RB750Gr3 is essentially an ethernet router that has 5 ports. It is supposed to be used in scenarios where there is not a need for wireless connectivity. Let's say that you are at home and working from a fixed desktop, then it is a solid option.

The thing to note about the Mikrotik hEX is that it is super affordable. You can find one for around $70 and you will be able to use it without having to install any sort of OS since it already has a built-in OS.

The major flaw with the Mikrotik hEX is that you will probably need another dedicated firewall device to give you decent protection. You will still be covered, but that coverage will be very limited if compared with a dedicated firewall device or a dedicated firewall solution.

5. Zyxel Next Generation VPN Firewall

The Zyxel Next Generation VPN Firewall is first and foremost a high-performance firewall. At the same time, it also helps to provide a reliable and efficient network. Security and home network safety concerns can easily be met with the Zyxel VPN Firewall since it protects these by establishing secure communications between two or multiple remote sites, connecting different VPNs, and maintaining data security.

These help to improve security by blocking access to spam or blacklisted websites, along with controlled access with an integrated firewall policy for highly specific blocking and filtering. This helps to create a unified firewall solution for all sorts of networks.

The Zyxel Next Generation VPN Firewall is a decent option in terms of price but for an average user that just wants to have a firewall for their home network, they can be a little overwhelmed by the number of features available. However, more advanced users might find the additional features to be more convenient.

One major thing that you have to keep in mind if you are opting for the CUJO AI Smart Internet Security Firewall is that it has been discontinued and no other replacement has been announced. This means that the device has limited support and might be outdated and prone to security risks in the future. Using such a device might not be an ideal solution as you are using a firewall to protect your network. If that primary purpose is not being fulfilled, then it might be a better idea to switch to an alternative firewall alternative.

How to Choose a Hardware Firewall?

Choosing the right hardware firewall can be challenging given the number of options available on the market. With varying price points as well as growing cyber threats, the compromise between security and budget constraints.

When choosing a firewall you need to be able to apply policies to certain end-users and allow access to those who need it to the applications in use. A more modern firewall can see and manage all of the applications as well as personal information on the network. The firewall you choose should also be able to limit traffic as well as cyber threats to the network by only allowing approved apps to be used. Firewalls should also have the bare minimum security infrastructure built-in like anti-virus, spam filtering, DPI (deep packet inspection), and app filtering to name a few.

Price and budget is obviously a primary concern for any individual or business. Modern hardware firewalls are affordable for most use cases. This costing is with regards to the costs associated with any sort of cyberattack and the harm it could bring to the business or even at an individual scale.
