Network firewalls are one of the oldest solution categories in the cybersecurity market. Much like firewalls that isolate parts of a building to prevent the spread of fire, network firewalls emerged to separate organizations' private networks from the public internet. Early firewalls enabled organizations to inspect incoming and outgoing traffic. Over time, firewalls evolved to include additional functionalities that allow organizations to examine traffic more deeply and provided organizations with more active security controls.
