Firewall Solutions are a core cybersecurity product, up there with endpoint protection as a foundational security tool every organization needs. As defending data and applications become more complicated, the security products built to withstand evolving threats also grow more powerful. The vast expansion of IoT devices, remote work, and advanced threats like ransomware has made protecting the perimeter both harder and more critical than ever, thus making firewall evaluation more complicated.

Network firewalls secure traffic bidirectionally across networks. Although these firewalls are primarily deployed as hardware appliances, clients are increasingly deploying virtual appliance firewalls, cloud-native firewalls from infrastructure as a service (IaaS) providers, and firewall as a service (FWaaS) offerings hosted directly by vendors.
