NGFW or Next Generation Firewall

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 firewall 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 gen firewall, and what is its difference from a traditional firewall?

What is a Next Generation Firewall?

NGFW or next gen firewall is a network security device that provides capabilities beyond what a traditional firewall could. A next gen 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 external 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.



Traditional Firewall



Port Blocking






Packet Filtering



Stateful Inspection



IP addresses and Domain Name Blocking



Intrusion Prevention System (IPS)


Deep Packet Inspection (DPI)


Encrypted Traffic Inspection


Application Control


Directory Integration


Things to Consider in an NGFW

There are five essential things to consider when getting a next gen firewall that includes:

The next gen 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. 

The current industry standard time to detect a threat is between 100 to 200 days. Fortunately, a next gen firewall is believed to address evolving security 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 gen 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.

The most important feature of an NGFW is to prevent breaches and keep your network and organization safe. It should include advanced capabilities to perform advanced malware protection quickly, IPS built-in to spot stealthy threats, a world-class threat intelligence organization, and URL filtering features that enforce URLs’ policies.

Essentially, your next gen 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 gen firewall is better equipped than the traditional firewall and eventually provides users with top security to address 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.

FAQs on Next Generation Firewall

A Next-Generation Firewall (NGFW) is a cyber security system that goes beyond standard firewalls to protect network fronts. Traditional firewalls identify suspicious traffic and deny network access based on a predetermined blacklist, while next-generation firewalls (NGFWs) contain capabilities like intrusion prevention and deep packet inspection.

Firewalls prevent any unwanted connections to your computer including those made by hackers attempting to steal your data and even allow you to choose which apps are allowed to connect to the internet, ensuring that you’re never linked unintentionally.

A next-generation firewall (NGFW) is a network security device that goes beyond a typical stateful firewall in terms of functionality. A next-generation firewall combines capabilities such as application awareness and control, integrated intrusion prevention, and cloud-delivered threat information, in addition to stateful inspection of incoming and outgoing network traffic.

The changing patterns of liquid crystals in IPS screens define them. The flexibility of the liquid crystal to tilt horizontally allows for greater viewing angles. For those who desire colour accuracy and consistency, IPS monitors remain the display technology of choice. When it comes to colour accuracy and viewing angles, IPS displays are second to none. When seen from various angles, the vast viewing angles afforded by IPS displays assist to produce superb colour.

NGFW operates near to the organisation, on levels 3–4, on the network, whereas WAF operates close to the app, on layer 7. WAF monitors the app and delivers warnings for unexpected activity caused by things like cross-site scripting (XSS), L7 DDoS, injection, failed authentication, and other similar attacks, whereas NGFW acts as a form of filter to protect against unauthorized network access. The internal network and its users are protected by NGFW, while the data passing across the app transcript is protected by WAF.
