A firewall is an important security product that monitors incoming and outgoing network traffic, and allows or blocks data packets according to a series of security rules. Firewalls can be used in software applications installed on servers or computers and physical hardware devices connected to internal networks.

The firewall is usually located between a trusted network and an untrusted network. But what is NGFW or next-generation firewall, and how is it different from traditional firewalls?

What is a next-generation firewall?

NGFW or next-generation firewall FortiGate as a firewall is a network security device that provides functions beyond the scope of traditional firewalls. Next-generation firewalls have additional features such as threat intelligence provided by the cloud, application knowledge and control, and built-in intrusion prevention.

In addition to access control, NGFW can also counter modern threats, such as advanced malware and application layer attacks, built-in intrusion prevention and threat defense.

Compared with traditional firewalls, NGFW usually has all the functions of traditional firewalls, that is, port blocking, proxy, packet filtering, and inspection.

Things to Consider

There are two key points to consider when purchasing a next-generation firewall, including:

  1. Comprehensive network visibility – The next-generation firewall must provide a holistic view of user activities and complete context awareness so that they can accept threats to activities on the network devices, threats originality, active websites, and applications.
  2. Fast detection time – Currently, the standard threat detection time is 100-200 days. Fortunately, suppose that the next-generation firewall can detect threats in a few seconds, detect security breaches in hours or minutes, and know when to prioritize alerts to take action against threats.
