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 proxy firewall, which has some functions and advantages.
The functions of a proxy firewall include acting as an intermediary to enhance privacy. Moreover, the advantages include more detailed access control, granular control, to protection against application-level threats.
This article will give you information on proxy firewalls, including definitions, functions, and the advantages they have.

What is a Proxy Firewall?
A proxy firewall is a type of firewall that works on the application layer. The overall packet payload will be examined in greater depth. This type of firewall will issue two connections to prevent two devices from connecting to each other.
The Functions of Proxy Firewall
The proxy firewall has several functions, from as intermediary to enhancing privacy. Here are some of its functions:
- As an intermediary: User requests will be forwarded through this device as an intermediary between internal network users and external servers.
- Caching: Cached data can be stored on this device, thus reducing the load on the network.
- Enhancing privacy: The user’s IP address can be hidden by this device thereby enhancing privacy while browsing the internet.
The Advantages of Proxy Firewall
The proxy firewall has several advantages, from more detailed access control, granular control to protection against application-level threats. Here are some of its main advantages in detail:
1. More detailed access control
One of the advantages of a proxy firewall is more detailed access control. With this device, administrators can apply specific security policies and monitor their activities with detailed logs.
2. Increased security
Increased security is another advantage of this firewall. It deeply examines network traffic from headers to payloads so that it can detect threats that other types of firewalls may miss.
3. Granular control
By using a proxy firewall, control will be more detailed over network access and activity. It will apply different security policies to different users or groups.
4. Network efficiency
With the caching capabilities of this firewall, network efficiency is improved. The storage of frequently accessed content makes page loading times faster and saves bandwidth.
5. Protects against application-level threats
Another advantage of a proxy firewall is that it can protect against application-level threats. Threats hiding in application data, such as malware, can be identified and blocked by this device.
Those are the definitions, functions, and advantages of a proxy 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.
