Best Network Firewall Software in 2026
Network firewall software helps manage the traffic moving through your network and the checks applied to it. Compared on concurrent connections and firewall throughput, these options also differ in deployment model, intrusion prevention, and SSL inspection. Site-to-site VPN, free-plan availability, and paid starting prices add further points to weigh against your needs. Names among the entries include NethSecurity, pfSense, and Arista NG Firewall. Consider the scale of traffic you handle, the inspection capabilities you require, and how the software would be deployed. The listed criteria can help you compare those practical requirements without treating every network environment as the same.
