Top 3 Firewalls for Your Business in 2023

More than half of today's cyberattacks are directed at small businesses because they generally have less network security, making them an easy target for hackers. According to the National Cyber Security Alliance, 60% of SMB's that are hacked tend to go out of business within 6 months.

Any organization or business handling large sums of data or connecting users online needs to have a firewall system in place. A firewall protects end users, customers, and data from all external parties so that businesses can safely operate without the fear of cybersecurity.

Keep reading to learn more about next-generation firewalls, cloud generation firewalls, and why they are so important for your business.

What is a Firewall?


A firewall is a device that sits in front of the network, monitoring all inbound and outbound traffic for probable threats. In the case that a firewall detects questionable activity, it processes those threats in accordance with the firewall rules and configuration. To put it simply, firewalls manage what is and isn't allowed to come and go through networks. 

This works so efficiently because firewalls are quick to the punch when anything problematic attempts to penetrate the network. When a data packet requests access, firewalls inspect the packet ahead of time to determine if the request is legitimate or a potential threat. 

Next generation firewalls take this approach a step further with Deep Packet Inspection, taking a deeper dive into the entire data packet to analyze its contents before coming to a security resolution.


Next-Generation Firewall


The term "Next-Generation Firewall" (NGFW) was first coined by Gartner Research, referring to the third generation of network firewall technology. 

These firewalls build on the previous generation of firewalls, which were limited to port/protocol inspection and blocking, by tightly integrating additional capabilities. These capabilities are made up of in-line deep packet inspection (DPI), intrusion prevention (IPS), and application-level traffic inspection.

Some NGFW's also enable TLS/SSL encrypted traffic inspection, website filtering, QoS/bandwidth management, antivirus inspection, and integration with third-party identity management systems like LDAP, RADIUS, and Active Directory.

Any NGFW's are going to give you a lot of the same security features:

  • Ability to block and allow traffic based on ports and applications
  • Remote access via VPN (or better yet zero trust network access, though its less common)
  • Malware scanning or web traffic
  • SSL decryption inbound or outbound
  • IDS/IPS Intrusion Detection/Prevention System)
  • URL and content filtering for websites

Why are Next-Generation Firewalls Important?


As more organizations began using online applications and SaaS services, it became obvious that purely inspecting ports and protocols was inadequate to provide constructive network security.

The most significant innovation at the time was the capability to provide Layer 7 application profiling and IPS, enabling highly granular policy enforcement based on specific applications. 

Next-generation firewalls are by now a mature solution category. Even so, the continuous mass migration of IT workloads to public-cloud IaaS platforms like Amazon Web Services and Microsoft Azure, is driving a push to expand the caliber of advanced firewalls yet again. 

While your organization's firewall, backup and recovery plan, and other features are critical to maintaining a secure infrastructure, you may be left with some security gaps that are not being filled.

Comparison of Business Firewalls


For managing multiple devices/sites and having good tech support, nothing beats Barracuda, our choice for best firewall. For the best price-to-value ratio, Fortinet would be the best choice. SonicWall consistently provides solutions with a lower TCO without needing to compromise on performance, so they will also give you a good bang for your buck. 

The benefits that set these apart from competitors come from user interface, ease/speed of configuration, price to value, and tech support. On the other hand, when comparing features, they're almost identical. 

Barracuda gets high ratings for value, advanced threat detection, ease of deployment and management, and quality of support. Their TINA tunnels are quite impressive for interconnecting multiple sites.  More than 150,000 organizations around the globe use Barracuda products, and they have a high presence in the market. Barracuda will go above and beyond in their customer service and support, which makes them top tier.   

Fortinet Fortigate's firewall solutions stand out from other competitors for several reasons, most valuable being the power and robustness of their firewalls. They use of a single piece of software as opposed to multiple pieces, which allows users to complete tasks more efficiently.

Similar to Barracuda, FortiGate has cloud deployment functionality, enabling control of the full network from one interface. While Fortinet and SonicWall share similar strengths, the greatest difference between the two is in support for cloud virtualization technologies, where Fortinet has more of an edge.

SonicWall is a good fit for those businesses that may be cost-conscious and are looking for more throughput at a fair price. With that being said, its cloud security, compared to Barracuda and Fortinet, is less mature.
