The presence of a firewall facilitates the guarding and controlling of incoming and outgoing data traffic, especially in network security. One type of firewall is a Next-Generation Firewall (NGFW), which has some functions and advantages.
The functions of a next-generation firewall include application control to filtering content. Moreover, the advantages include intrusion prevention systems, advanced malware protection, and cost efficiency.
This article will give you information on next-generation firewalls, including definitions, functions, and the advantages they have.

What is a Next-Generation Firewall?
A next-generation firewall is a type of firewall that offers more advanced features than traditional firewalls, such as deep inspection of network traffic, application awareness, and intrusion prevention capabilities.
NGFWs are at the top of the firewall hierarchy because they are the most up-to-date systems. It offers captivating packet filtering.
The Functions of Next-Generation Firewalls
The next-generation firewall has several functions, from application control to filtering content. Here are some of its functions:
- Application control: Can identify and control applications running on the network to block or restrict access to potentially malicious applications.
- Identify users: Can identify users connected to the network using different devices or from different locations.
- Filtering content: Content accessed by users will be filtered so that access to unwanted content will be blocked.
The Advantages of Next-Generation Firewalls
The next-generation firewall has several advantages, from an intrusion prevention system, advanced malware protection, to cost efficiency. Here are some of its main advantages in detail:
1. Intrusion Prevention System (IPS)
One of the advantages of a next-generation firewall is that it has an intrusion prevention system (IPS). This device can monitor network traffic for signs of attack or suspicious activity, and then the IPS will automatically block or reject.
2. Deep Packet Inspection (DPI)
Having a Deep Packet Inspection (DPI) system is one of the advantages of an NGFW. This device is capable of performing a deep inspection of data packets from the header to the contents. This allows it to detect malware, exploits, and anomalies that may be hidden.
3. Advanced malware protection
Advanced malware protection is another advantage of the next-generation firewall. The spread of malware, including ransomware and other attacks, can be detected and prevented by this device.
4. Improve network visibility
By using an NGFW, network traffic and application usage can be viewed in detail. This ability makes potential threats well detected, and network performance can be optimized.
5. Cost efficiency
Another advantage of the next-generation firewall is that it can reduce costs. This device has various security functions so that it can reduce operational costs by eliminating the need for multiple security solutions.
Those are the definitions, functions, and advantages of a next-generation firewall that you need to know. Another thing to note is that firewalls on the market must pass the certification test from the Directorate General of Digital Infrastructure (DJID).
Firewall regulation is based on the Ministerial Decree (KEPMEN) No. 60 Tahun 2022, which requires all radio frequency-based devices to meet specific technical standards before being sold in the country.
With a DJID certification, users can feel calm about using a firewall whose quality and security are guaranteed. For manufacturers or importers of firewalls, obtaining certification from DJID is a mandatory step before the device can be officially marketed in Indonesia.
To simplify the certification process, Type Approval Certification Services for ICT Products are available to assist with this process as a reliable solution. -UN.
