The pfSense project is a completely free network firewall distribution, placed on the FreeBSD operating system along with a custom kernel that contains third party free software packages for extra functionality.
pfSense software, using the help of the package system, can easily give the same, or better, functionality of common commercial firewalls without any of the artificial limitations. This comes from a web interface for the configuration of all included components. You are required to have any UNIX knowledge and will not have to use the command line for anything as you will not have to manually edit any rule sets.
The features of pfsense are flexible and customisable, these features are: Network Address Translation (NAT), Multi-WAN, Server Load Balancing, Virtual Private Network (VPN), Dynamic DNS and more.
Made from Fortinet’s security platform, Fortigate allows a one-stop-shop reach to network protection which includes a firewall, Virtual Private Network (VPN), as well as application control, antimalware, antispam, IPS, wireless control, and web filtering.
Fortigate gives two different types of firewall, both the enterprise firewall and the next generation firewall. Depending on the firewall you are looking for, Fortigate may tailor to you. Both are very high-performance firewalls, specifically made for larger businesses.
Comodo Internet Security Pro
Comodo grants an amazing firewall capable of efficiently filtering ICMP and outbounds TCP and UDP traffic before monitoring any connection that is made within your network. Furthermore, it recognizes any connection that is not safe.
A downside to this firewall can be the pop-up notifications that it pesters users with. Those who would like a silent firewall that works behind the scenes may wish to use something different. This, however, could be forgiven due to Comodo’s high-quality response to any outside attempts who try to methodically uncover user data with things such as keyloggers; Comodo detects these and stops them before any data is stolen.
Sophos UTM Essential Firewall is the free version of Sophos UTM software and provides core security functions for businesses that are medium-sized and in need of network protection.

Any businesses who require effective logging and reporting capabilities, then Sophos UTM can provide hardware reports in real-time.
VirtualPF is an excellent firewall which allows Loadbalance/Failover your firewall for better stability which includes attack mitigation. This firewall protects any virtual environment, Hyper-V, XenServer, VMware, and Proxmox. All of these will need environment protection against threats and will also need a solid and scalable firewall. Once VirtualPF is clustered, it uses the power of loadbalancing, mixed with the safety of failover services and custom IP addresses which ensures your network is scalable.
VirtualPF is very powerful with many features and functions, comes with a user-friendly interface, and is completely free. Another thing this firewall provides is a built in intrusion detection and prevention, it inspects any inbound and outbound network activity then identifies suspicious patterns which may indicate someone is trying to break into or compromise your network or system.
