A quality enterprise firewall should be a top priority for businesses building a secure infrastructure. These tools protect endpoints and monitor network traffic, blocking bad actors from breaching sensitive data and damaging networked assets.

Firewalls are responsible for processing a large amount of the incoming traffic on an enterprise network. Although they aren’t responsible for the security of the entire infrastructure, they’re a critical piece of network protection. To select a firewall that fits your organization, your team should consider the environments it supports, the flexibility of its security policies, and the performance requirements for your top applications and workloads.

Top Firewall Software

1. Fortinet

Fortinet, headquartered in Sunnyvale, California, is a leader in cybersecurity services, offering a long list of tools like physical and software firewalls, antivirus software, and a variety of other endpoint security products. FortiGate is Fortinet’s primary firewall product offering.

Key features

Fortinet offers multiple types of firewalls, including:

  • Container firewalls
  • Virtual firewalls
  • Hardware firewall appliances

Fortigate is a sizeable firewall solution, but it’s not a massive security platform like Palo Alto or Forcepoint and won’t require a deployment as extensive. It’s a good solution for smaller enterprises that may not feel comfortable investing in a more extensive network security platform in their current position.

Fortinet also offers a seventh-generation network processor (NP7) for hyperscale data centers. This processor powers Fortinet’s NGFWs so they can support high-performance security workloads like sensitive data research. If your business is in the medical industry and does regular research on large volumes of data, consider Fortinet’s new hyperscale processor.


  • Highly scalable
  • Well-equipped to handle work-from-anywhere staffing structures
  • Part of the centralized, coordinated FortiOS security package
  • AI-powered enhancements

User review

A Fortigate reviewer on Gartner’s Peer Insights page says, “Fortigate provides our company with a network security framework that is designed to provide threat prevention and performance while being simple to use. Its approach is efficient and has great capabilities. We implemented a unique security program that not only reduced our security posture but also provided that all of our actual, online, and cloud-based technology was appropriately protected, allowing our employees to concentrate on growing profits rather than worrying about protection.”


Fortinet was designated as a leader in the 2021 Gartner “Magic Quadrant” for network firewalls ranking.

5. Cisco

Cisco has long been a leader in the network security space. The company, headquartered in San Jose, California, offers many enterprise and consumer-grade products related to networking, including Cisco Secure Firewall. This firewall is available as a stand-alone product or as part of the Cisco Umbrella unified security package.

Key features

Cisco’s TLS Server Identity and Discovery capability keeps TLS 1.3 traffic encrypted rather than decrypting it and potentially exposing the content to threat actors on the network. Businesses using Server Identity and Discovery can maintain Layer 7 OSI security policies without using the high processing power required to decrypt pieces of traffic. Administrators can still view the network traffic, too. This is a beneficial feature for businesses that use TLS 1.3 and are focused on intensive network security.

Through the Cisco Secure Firewall Management Center, IT and security teams can manage their firewalls as well as application control, URL filtering, and malware defense policies. This central console helps admins manage multiple parts of their network security in one place. Consider Cisco if your business needs to create policies for all your distributed applications, particularly ones that process sensitive data.


  • Superior visibility into traffic and application environments
  • Behavioral analysis for logged data from all Cisco Secure Firewalls on the network
  • Key component of Cisco’s unified security package

User review

A reviewer at Gartner Peer Insights says, “We have been using the Cisco Secure Firewall in our company for quite a long time now. It is a proactive threat defense tool that tops all attacks even before they spread through our network. This tool has solved many of our business problems such as it provides VPN remote access allowing employees to work at the home office and be able to even access the intranet. The customer support of Cisco Secure Firewall is just spectacular and absolutely top-notch. We are highly satisfied with the quality of support it provides us.”


Cisco was designated as a Leader in the 2021 Gartner “Magic Quadrant” for network firewalls.

Bottom line

The volume of options available for enterprise firewalls can feel overwhelming, but taking a methodical approach can help. To start, narrow your choices by eliminating options that are out of budget or require more time than you’re able to spend on training and onboarding. The best firewall software for you may not be the most well-known — it may be helpful to reach out to your network to learn about which firewalls are being used by peer companies.
