While Standard firewall features had features like packet filtering, network address translation and VPN, NGFW has been made “Application Aware” i.e. capable of identifying applications and applying controls at the application layer. NGFW has also gone step ahead by improved decision making like using reputation services or identity services such as Active Directory. Another major driver for the adoption of NGFW is the benefit of reducing the complexity of managing disparate security products.
