As we move into the new year, the cybersecurity landscape continues to evolve, and small businesses are often the victim of nascent cyber threats. The reason is clear: there are no shortage of potential victims, and many small businesses simply don't have the resources or expertise to defend themselves effectively. At the same time, we know that about half of all small businesses that suffer a major data breach go under within a year. That sobering fact should incentivize far more small firms to pay serious attention to their cybersecurity. One of the first and most important steps is to ensure you have a properly configured firewall. Let's take a look at some of the top candidates for firewalls to protect your small business" in 2024.
There are many network security appliances at the higher end of the affordable spectrum, from the $549 range to $1,000 and above, that can safeguard a small business's network. Advanced, affordable network security appliances are our top recommendation for the average business, and in our experience, they can offer a level of protection superior to most other options available today.
Why is that? Performance. Vendors of network security appliances aren't shying away from the fact that top-shelf products in this class have a suite of features explicitly optimized for network traffic, as well as a pretty good price-to-performance ratio. But once you take a closer look, performance is where the products in this category separate themselves from more commonly used, consumer-grade alternatives.
Small businesses can gain a variety of benefits from investing in a dependable firewall solution.
A small business has many types of firewalls to choose from for fulfilling its security needs. Although these firewalls perform the same basic task and share some features, they are quite different in their specifics. Here are the deployment methods and characteristics of three types of firewalls that a small business might consider:
Firewall Technologies:
When small businesses know the kinds of firewalls that are available, and the types of protections they provide, they can make smart, informed decisions about how to securely protect their business. The bad guys are always trying to get in, and firewalls are the first line of defense in keeping them out. More than just understanding, though, is grasping the firewall advantages—why an organization should choose the category of firewall it does.
Here are five popular options we think buyers often consider.

For small businesses, a firewall is vital. It offers network security and, most significantly, protects sensitive data and resources from various kinds of cyber threats. It plays an essential role in managing and monitoring network traffic, preventing unauthorized access, and safeguarding against many online attacks, hackers, and data breaches. A well-set-up firewall is an integral part of any small business that has a sturdy cybersecurity strategy.
For small businesses, Unified Threat Management firewalls offer an all-in-one cybersecurity solution. UTM firewalls integrate several security features—such as anti-virus, anti-spyware, intrusion prevention, and web filtering—that work together to thwart cybercriminals. By placing UTM firewalls at the perimeter of their IT infrastructure, small businesses are able to reduce both management complexity and the total cost of maintaining multiple security solutions. A next-generation firewall (NGFW) is another good option for small businesses. NGFWs offer some enhanced features that UTM firewalls lack, especially in application control and advanced threat detection.
A small business can expect to pay hundreds to thousands of dollars for a firewall. The basic cost is not too different from what a VPN would run, just under $300 to $400 per year for a service that covers around 50 devices (although a basic firewall function may be built into your high-end router). If a small business opts instead for a sophisticated, all-inclusive network security solution, then the annual price might run from $3,000 to $5,000 and up, with some vendors pricing their security services on a per-user, per-month basis.
The effectiveness of a firewall greatly depends on its configuration and how well it aligns with the network for which it serves as a point of protection. Hardware firewalls, such as those made by Netgate and Fortinet, provide potent capabilities primarily useful to network environments found at the business level. On the other hand, software firewalls—often part of antivirus programs or operating systems—can and do protect quite adequately the point at which individual users can safely use the internet.
A firewall's security level largely depends on how it's set up and the environment in which it runs. We tend to view hardware firewalls as the most secure. This is because they have the resources to run, cover the network sufficiently, and often are configured to be highly available. However, the most secure setup is the one that not only is properly configured but also is integrated into a multi-layer network security strategy.
