A firewall is an essential security product that monitors the incoming and outgoing network traffic and permits or blocks data packets based on a set of security rules. A firewall is available in software applications installed on a server or a computer and physical hardware appliances connected to an internal network. A firewall usually sits between a trusted network and an untrusted network. But what is an NGFW or a next-generation firewall, and what is its difference from a traditional firewall?
What is a Next-Generation Firewall?
NGFW or next-generation firewall such as FortiGate is a network security device that provides capabilities beyond what a traditional firewall could. A next-generation firewall has additional features like cloud-delivered threat intelligence, application awareness and control, and integrated intrusion prevention.
In addition to access control, NGFWs can also fight modern threats such as advanced malware and application-layer attacks, integrated intrusion prevention, and threat intelligence sources.
NGFW vs Traditional Firewall
NGFWs typically have all the features of a traditional firewall, namely port blocking, proxying, packet filtering, and inspection. Additionally, some features differentiate traditional firewalls and NGFWs as below.

|Intrusion Prevention System (IPS)||✓|
|Deep Packet Inspection (DPI)||✓|
|Encrypted Traffic Inspection||✓|
Things to Consider in an NGFW
There are five essential things to consider when getting a next-generation firewall that includes:
Extensive Network Visibility
The next-generation firewall should provide a holistic view of activity and full contextual awareness for the users to see threat activity across networks and devices, the originality of a threat, and active applications and websites.
Quick Detection Time
The current industry standard time to detect a threat is between 100 to 200 days. Fortunately, a next-generation firewall is believed to detect threats within seconds, detect the presence of a successful breach within hours or minutes, and know when to prioritize alerts to take action in eliminating threats.
A next-generation firewall should seamlessly integrate with other tools, automatically share threat information, and automates security tasks like impact assessment, policy management and tuning, and user identification.
Advanced Security and Breach Prevention
The most important feature of an NGFW is to prevent breaches and keep your network and organization safe. It should include advanced capabilities to detect advanced malware quickly, IPS built-in to spot stealthy threats, a world-class threat intelligence organization, and URL filtering features that enforce URLs’ policies.
Flexible Management Options
Essentially, your next-generation firewall should be able to meet your unique requirements and customize with features that meet your needs, manage every use case, and have options to choose from a variety of throughput speeds.
The Benefits of a Next-Generation Firewall
Block Malware – Unlike traditional firewalls, the NGFW can block malware and threats. This has never been done before by the traditional firewall, allowing you to have better security on your network and organization.
Better Equipped – Additionally, a next-generation firewall is better equipped than the traditional firewall and eventually provides users with top security against any Advanced Persistent Threats (APTs).
Low-Cost Option – Despite their advanced capabilities, NGFWs can be a low-cost solution for organizations to upgrade their basic firewall security and system.
