What is Next-Gen Firewall?


In today’s digital age, security threats are increasing at an alarming rate. With hackers becoming more sophisticated every day, it is essential to protect your network against cyber attacks. One technology that has emerged as a game-changer in the world of cybersecurity is Next-Generation Firewall (NGFW). But what is NGFW exactly? In this blog post, we’ll delve deep into the concept of next-gen firewall and how it can help safeguard your organization from emerging threats. So buckle up and get ready for a thrilling ride!

What is a firewall?

A firewall is a system that helps protect your computer from unauthorized access. It does this by filtering traffic coming into and out of your network. A firewall can be hardware, software, or both.

Next-generation firewalls (NGFWs) are the latest generation of firewalls. They offer better protection than traditional firewalls by adding features like application control and intrusion prevention. NGFWs also offer better performance, so they can handle more traffic without slowing down your network.

What is a next-generation firewall?

A next-generation firewall (NGFW) is a type of firewall that has been designed to offer better protection against the latest types of cyber threats. NGFWs typically include features such as application control, intrusion prevention, and advanced malware protection.

Unlike traditional firewalls that focus mainly on blocking incoming traffic from known attackers, NGFWs are designed to also protect against new and unknown threats. This is achieved by inspecting traffic at a deeper level and identifying malicious activity even when it is disguised or encrypted.

NGFWs are an important part of a comprehensive security strategy and can help organisations to better protect their networks and data from sophisticated cyber attacks.

What should I look for in a next-generation firewall?

When shopping for a next-generation firewall, there are several key features to look for. The firewall should have the ability to inspect all traffic passing through it, including encrypted traffic. It should also have advanced application control, so that you can control which applications are allowed to communicate with each other on your network. Additionally, the firewall should offer intrusion prevention capabilities, so that it can detect and block malicious traffic before it reaches your network.

The benefits of next gen firewall

As enterprises face an ever-growing number of network security threats, they are turning to next generation firewalls (NGFWs) to provide the advanced protection they need. NGFWs are purpose-built devices that offer a number of benefits over traditional firewalls, including:

1. Improved performance: NGFWs are designed to inspected every packet passing through the firewall, which results in increased performance and fewer dropped packets than traditional firewalls.

2. Increased security: NGFWs include features such as intrusion prevention and application control that allow them to more effectively protect networks from sophisticated attacks.

3. Greater visibility and control: NGFWs provide detailed logging and reporting capabilities that give administrators greater visibility into network activity and allow them to more effectively manage traffic flows.

4. easier to deploy and manage: NGFWs typically come with easy-to-use management interfaces that make them simpler to deploy and manage than traditional firewalls.

How to choose the right next gen firewall for your business

There are a few key considerations when choosing the right next gen firewall for your business. The first is to identify what network security risks are most relevant to your organization. For example, if you’re primarily concerned with data breaches then you’ll want to prioritize features like advanced malware protection and intrusion detection/prevention. On the other hand, if you’re more worried about distributed denial of service (DDoS) attacks then you’ll want to focus on firewalls with robust DDoS mitigation capabilities.

Another important consideration is whether you need a hardware or software-based firewall solution. Hardware-based firewalls tend to be more expensive but offer better performance and scalability. Software-based firewalls are less expensive and can be run on commodity hardware, but they may not be able to keep up with high-traffic networks.

Finally, you’ll need to decide on a deployment model that fits your organizational needs. On-premises firewalls are typically best for large enterprises with complex network architectures. Cloud-based firewalls are more flexible and easier to manage, making them a good choice for small businesses and organizations with limited IT resources.


Next gen firewalls offer a great solution for organizations seeking to protect their data networks from malicious attacks. By combining traditional firewall features with advanced security features, next gen firewalls provide businesses with an extra layer of protection against threats that regular firewalls cannot detect or stop. As the cyber threat landscape continues to evolve, it is essential that businesses keep up with the latest technologies and solutions in order to protect their valuable data and information. Next gen firewalls are one such technology that can help businesses stay ahead of the curve when it comes to cyber security.
