Abstract

This paper provides a comprehensive review of firewall technologies, focusing on the evolution from traditional firewalls to Next-Generation Firewalls (NGFWs). The study examines various firewall types, including packet filtering, stateful inspection, application-layer, and next-generation firewalls. It highlights their key features, advantages, and limitations. The paper compares Fortinet's FortiGate NGFW with Cisco's Adaptive Security Appliance (ASA), emphasizing the advanced capabilities of NGFWs in addressing modern cybersecurity challenges. Key aspects covered include virtualization, SSL/TLS inspection, and automation features. The research underscores the importance of NGFWs in protecting hybrid environments and handling increasing volumes of data-intensive traffic and cloud-based applications.
