TRADITIONAL FIREWALL VS NEXT GEN FIREWALL ngfw

Introduction to Traditional & Next Gen Firewalls

With advancement in technology and new threats being introduced in the ever dynamic IT world, security has become quite essential. And so has the need for more advanced and smarter products. One such case is that of NGFW (Next Gen Firewall).

Traditional firewalls have been there for quite long and offered protection to customer network based on controlling protocols and ports and restricting traffic to and from specific IP addresses. However, these days attacks have become more innovative and have started targeting applications and services instead of ports like 80 and 443 etc.  (http and https)

  • While Standard firewall 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.
