What You Should Know: Next Generation Firewall


Next-generation firewalls, as its name implies, are a more advanced version of existing firewalls that provide the same benefits. While both next-generation and classic firewalls have the same goal of protecting an organization’s data assets and network, there are some differences between them. NGFW uses VPN support and dynamic and static packet filtering, just like classic firewalls, to ensure that all connections between the web, internet, and firewall are logical and safe. Both next-generation and classic firewalls should be able to map IP addresses to network and port addresses.(next gen firewall)

Static packet filtering to restrict packets at the interface point to network traffic is one of the primary similarities between classic and next-generation firewalls. They may also be able to do stateful packet inspection, network, and port address translations, as well as establish VPN connections.

Traditional firewalls and next-generation firewalls have only a few key distinctions. The most significant distinction is that NGFWs, in addition to simple port and protocol inspection, do deep packet inspection by evaluating the data in network packets. Another significant distinction between standard firewalls and next-generation firewalls is the capacity of NGFWs to filter packets based on applications. These firewalls have a lot of control and visibility over the apps they can recognise by analysing and matching signatures. They can employ safelists or a signature-based IPS to differentiate between safe and undesired programmes, which can be recognised using SSL decryption. NGFWs, unlike most traditional firewalls, also feature a way for receiving future upgrades. Another significant distinction is that NGFWs include application-level inspection, intrusion prevention, and the capacity to respond on threat intelligence data.

NGFWs also integrate new threat management technologies while extending traditional firewall functionality such as NAT, PAT, and VPN support to operate both in routed mode (where the firewall acts as a router) and transparent mode (where the firewall acts like a bump in the wire when scanning packets).


The unique characteristics of NGFWs result in unusual benefits for the organisations that use them:
1. A Next-Generation Firewall can prevent malware from accessing a network, which existing firewalls are incapable of doing.
2. NGFWs are well-prepared to deal with APTs (Advanced Persistent Threats).
3. For enterprises wishing to increase their overall security, Next-Generation Firewalls can be a cost-effective choice. They can combine the advantages of firewalls, antiviruses, and other security software into a single solution.
It has elements like application awareness, inspection services, a protection system, and an awareness tool that all help the offering.


A firewall is a must-have for any business. In today’s society, however, creating a firewall for the next generation is critical. Every day, new threats to personal devices and massive networks emerge. The versatility of NGFW protects devices and businesses against a variety of threats. While these firewalls are not the best answer for every business, security professionals should think about the advantages that NGFWs may provide, since they have the most potential.


Organizations of all sizes, from small businesses to large corporations, benefit from the greatest next-generation firewalls in five ways. Ensure that your NGFW meets the following criteria:

Preventing infringement and enhancing security
The primary goal of a firewall should be to prevent security breaches and keep your company safe. However, because blocking tactics do not always succeed, your firewall should also have enhanced capabilities to detect complex malware if it manages to get past your earlier defences. Invest in a firewall that possesses the following capabilities:
Attempting to thwart an attack before it begins
The newest generation of intrusion prevention systems (IPS) is better suited to detect and stop hidden threats fast.
URL filtering enforces regulations on millions of URLs, including built-in sandboxing and powerful malware protection that monitors file performance in real time to quickly discover and remove threats.
A world-class intelligence organisation that acts as a bulwark against new dangers by providing the most up-to-date intelligence.
