Abstract
The increasing complexity and proliferation of modern cyberattacks, such as modern Persistent Threats (APTs), ransomware, and encrypted threats, have rendered classic stateful firewalls obsolete. Next-Generation Firewalls (NGFWs) have become indispensable to protection, featuring deep packet inspection, intrusion prevention systems, application control, and threat intelligence. This survey provides an in-depth review of the evolution, capabilities, and effectiveness of NGFWs in combating modern cyber threats; which is needed for various applications, such as social protection system, social determinants of health, and others. our review involves support from a literature review spanning 2015 to 2025. We combine information from academic research and industry studies to evaluate how well technologies that support NGFWs work, focusing on their strengths in application-layer visibility and threat mitigation. The paper talks about big problems, like how advanced features like SSL/TLS inspection can slow down performance and how security protocols need to be adaptable and driven by AI. Finally, we end with suggestions for how to successfully deploy and ideas for future research, such as how to combine artificial intelligence and zero-trust architecture to make next-generation firewalls more effective against new threats.
