Next-Generation Firewall vs Traditional Firewall: What’s the Difference

 In Blog

As the name implies, the firewall functions within the company’s scope, which is “wall,” serves as a barrier. This barrier is created between the computer and the internet network used by the parties to protect the company from various attacks and cyber threats originating from the internet network.

Along with the development of sophisticated technology, ordinary firewalls or traditional firewalls are no longer relevant to protect companies optimally.

Since the firewall is one of the crucial aspects of cyber security to protect the system from external threats, the next-generation firewall is developed to replace the traditional one and provide protection that suits the current company’s needs. What is a next-generation firewall, and what is the difference between a next-generation firewall and a traditional firewall?

Definition of Next-Generation Firewall

Cited from Gartner, the next-generation firewall is a cutting-edge security solution used to ward off all cyber-attacks from third parties. Thus, the data owned by the company cannot be changed, stolen, or tampered with easily. Unlike traditional firewalls, next-generation firewalls inspect all applications, attacks, traffic, and content across multiple platforms and investigate how cyber-attacks work.

Comparison of Next-Generation Firewall and Traditional Firewall

Next-generation firewalls are more sophisticated than traditional firewalls; both provide the same benefits to companies. Like traditional firewalls, next-generation firewalls use static filtering, dynamic filtering, and VPN support to ensure that all connections within the network, internet, and firewall are valid and secure. Both types of firewalls can also translate network addresses and ports to plot the IP.

There are some differences between a next-generation firewall and a traditional firewall. The most apparent difference between those is the ability of the next-generation firewall to filter any traffic based on the application. This sophisticated firewall allows for more visibility and control over the applications, allowing the identification using analysis and signature matching. The next-generation firewall users can use a whitelist or a signature-based IPS to distinguish between secure and non-secure applications and then place them using SSL decryption. Unlike most traditional firewalls, next-generation firewalls also attach the path to receive future updates.

In simpler terms, here are the differences between next-generation firewalls and traditional firewalls:

Traditional Firewall Next-Generation Firewall
Traditional firewalls provide stateful inspection of incoming and outgoing network traffic Next-generation firewall provides stateful inspection of incoming and outgoing network traffic along with other additional features.
Traditional firewalls provide partial application control and visibility only. Next-generation firewall provides comprehensive application control and visibility.
Traditional firewalls work at layer 2 to layer 4 only. Next-generation firewalls work at layer 2 to layer 7.
In traditional firewalls, managing security tools separately is quite expensive. By the next-generation firewall, users can easily install, configure, or integrate security tools. Therefore, it may reduce administrative costs.
Traditional firewalls cannot decrypt and inspect SSL traffic. SSL traffic can be decrypted and inspected by next-generation firewall.
The Integrated Intrusion Protection System (IPS) and Intrusion Detection System (IDS) are deployed separately in traditional firewalls. The Integrated Intrusion Protection System (IPS) and Intrusion Detection System (IDS) are integrated

 

Those are some of the differences between next-generation firewalls and traditional firewalls. Both offer the same benefit for companies, which is to ward off all cyber-attacks from third parties. Thus, the data owned by the company cannot be changed, stolen, or tampered with easily. The difference lies in its capabilities advancement since the next-generation firewall is designed with several additional features relevant to the company’s digital landscape growth.
