10 best network firewall solutions for businesses

Since the first commercial firewall in 1991, network security needs and technology have evolved significantly. While many businesses still use hardware firewalls, the rise of virtual network firewalls has made it easier to achieve the same functionality without the maintenance and complexity of physical firewalls.

Software firewalls offer effective network protection in a simpler, easier-to-manage way compared to hardware options. This article reviews our top 10 picks for software network firewalls to help you choose the best one for your business.

Key features to look for in a firewall

Focus on features that provide strong network protection while meeting the specific needs of your business. The right firewall solution should offer visibility, easy integration, and scalability to ensure nothing gets misconfigured as your company grows:

1. Visibility and control. A good firewall solution needs to provide deep insight into your network traffic and applications, especially for businesses needing access control to meet regulations. Next-generation firewalls with strong threat intelligence can help you stay compliant.
2. Easy integrations. Ensure the firewall provider offers solutions that integrate well with your current systems, like deep packet inspection tools or data centers. It should strengthen your overall network security by fitting smoothly with your other security features.
3. Updates and maintenance. Choose firewall vendors that provide regular updates and proactive product development. Focus on solutions that are frequently updated, well-maintained, and show consistent growth. Providers should offer public release notes, regular updates, and clear communication with customers. It’s crucial to ensure that security features stay current. Automated updates and clear versioning also reduce manual work for IT teams,
4. Hybrid network support. If your business operates across both on-premises and cloud setups, choose a firewall solution that supports hybrid infrastructures.
5. Scalability. As your business grows, your firewall solution should scale without significant cost increases. For example, as your setup becomes more complex, you’ll need more firewall rules. It’s wise to check the number of rules included in each plan before purchasing, as the cost difference between plans can sometimes be steep. This helps maintain strong network protection as your infrastructure expands.

When picking a firewall, focus on features that offer strong security and fit your setup. Prioritize solutions with automation features to reduce manual work. It will save time and help manage security across complex infrastructures.

How to choose the best firewall for your business

When picking the right firewall for your company, you need to weigh several important factors:

1. Security needs. Start by assessing your network security risks. If you’re a larger organization facing more threats, choose a next-generation firewall with a strong intrusion prevention system, advanced threat intelligence, and encryption to protect sensitive data across all layers. Smaller businesses should focus on essential features like packet filtering, malware defense, and network monitoring without overcomplicating the setup. Make sure the firewall solution aligns with the size and complexity of your network to avoid unnecessary costs or gaps in protection.
2. Ease of use. The firewall should be easy to deploy and manage, especially if your IT resources are limited. Network firewalls with simple, user-friendly interfaces can reduce the time spent on managing network protection. Opt for solutions that offer automation for tasks like network traffic monitoring, deep packet inspection, and access control to save time.
3. Support. Reliable customer support is crucial when setting up and maintaining a firewall. A firewall vendor that provides 24/7 support ensures issues are resolved quickly, minimizing downtime. If your business uses data centers or hybrid cloud setups, look for a vendor that offers proactive support to avoid misconfigurations and keep your security features running smoothly.
4. Cost. While the price is important, consider the long-term value. Cheaper options may lack the scalability and advanced features you'll need as your business grows. Make sure the solution can scale with your business, especially if you expand your data centers or cloud environments, without incurring hefty costs when upgrading.
5. Compatibility. Ensure the firewall integrates seamlessly with your existing infrastructure, whether it's cloud services, VPNs, or identity management systems. A firewall that works well with other security tools, such as intrusion prevention systems and threat management platforms, strengthens your overall network security and prevents integration issues.
6. Performance and scalability. As your business grows and network traffic increases, your firewall must be able to handle the additional load without sacrificing performance. Whether securing sensitive resources or managing remote access, the firewall should maintain consistent network protection and scale efficiently to meet your evolving needs.

Overall, different firewall solutions suit different business needs. Large options like Fortinet and Palo Alto are ideal for enterprises. Mid-sized businesses may find NordLayer or Perimeter 81 effective, while Todyl targets MSPs and MSSPs. Smaller options like Banyan Security fit smaller budgets. Choose based on your security needs and resources.
