What are the advantages of next-generation firewalls?

Enterprises are turning to next-generation firewalls for enhanced security due to the sophistication of recent cyberattacks and sophisticated hacking techniques. For example, applications are being exploited by new web-based malware and intrusion attempts that get over perimeter security. Although next-generation firewalls are the only ones that can offer adequate protection in today's shifting threat landscape, firewalls are still a standard security solution for most businesses.

Since this technology is relatively new, some of us are still determining what the term next-generation firewall means, what it adds to the old firewall, and why it is required. A Next-Generation Firewall (NGFW) is, to put it simply, a firewall that adds additional layers of security to the traditional firewall's perimeter and the standard port/protocol protection.

Your security posture may be standardized across all cloud-based firewalls, including virtual, private, and public ones, with the help of Databytes' firewall services. In this blog, we'll go through the main benefits of the new generation firewall, which is an update to the conventional firewall.

Advantages of Next-Generation Firewalls

1. Multiple Layers of Security

A basic antivirus program that is preinstalled on your smartphone is no longer sufficient in today's digital world. To prevent cyberattacks, you need to have numerous distinct levels of protection in place. NGFWs go further and inspect traffic from layers 2 through 7 of the OSI model, whereas standard firewall provides single-layer protection by restricting access through ports using data from layer 4 of the OSI model. This gives businesses more understanding of the activities on their network, including who, when, and where accessing harmful websites.

2. Elements of application-level security like IDS and IPS

Application security features like intrusion detection systems, or IDS, and intrusion prevention systems, or IPS, have been added by NGFWs.

These programs aid in streamlining packet-content filtering. These functionalities include recognizing, examining, and responding to abnormal departures from the expected events, threat signatures, and user-based attacks.

3. Application Awareness

Traditional firewalls frequently block standard application ports or services on a network to manage application access and keep an eye on specific dangers. Although the complexity of network communication makes it harder for typical firewalls to detect the targeted port, many applications use many or different ports.

Additionally, these ports are utilized in various other methods, like tunneling, where a network protocol is encapsulated within the packets delivered by the second network and abstracted at the end.

4. Threat prevention

NGFWs come with antivirus and malware protection that is regularly updated automatically whenever new threats are found, in contrast to traditional firewalls. In addition, the NGFW device reduces attack vectors by restricting the apps it can run.

Then, it checks each of the allowed applications for any concealed vulnerabilities or potential data leaks, reducing the dangers posed by unauthorized applications. Of course, with typical firewalls, it cannot minimize bandwidth utilization from any unnecessary traffic, but doing so helps.

5. Network speed

Although many manufacturers of conventional firewalls assert that they can provide a specific throughput from every port, the truth is significantly different.

When activated, the increased amount of security tools and services slows down the network speed. As a result, the speed has been reduced by approximately a third of the actual claimed speed by the time the traffic reaches the end user. In contrast, regardless of the quantity of security services, next-generation firewall throughput remains constant.
