Why Firewalls Are Not Enough in Today's Cybersecurity Landscape
Firewall technology has mirrored the complexities in network security, evolving significantly over time. Originally serving as basic traffic regulators based on IP addresses, firewalls advanced to stateful inspection models, offering a more nuanced approach to network security. This evolution continued with the emergence of Next-Generation Firewalls (NGFWs), which brought even greater depth through data analysis and application-level inspection.
