There are many types of Firewalls currently in use. If you wish, you can find the information you are looking for in our subheadings about what these systems are and what they do.

Next Generation Firewall
Next generation Firewall is a concept known by the abbreviation sri lanka telegram NGFW and its Turkish equivalent is the new generation firewall. This type of Firewall also supports additional features such as intrusion prevention systems, encrypted traffic control and virus protection. The most important feature of the system is also known as deep packet inspection. Deep packet inspection is suspicious of requests from all sources, no matter how reliable the source is. Since in-depth inspection is performed, the system is called deep packet inspection.


Proxy Firewalls
Proxy Firewall firewalls provide application-level security control. Unlike other systems, proxy acts as a bridge between two systems. With this system, requests are sent to the firewall. The request is filtered and the request is approved or blocked depending on the reliability of the request. Proxy filters by monitoring traffic of protocols such as FTP and HTTP. It also uses deep packet inspection during this process.

Network Address Translation Firewalls
This type of Firewall is simply called NAT. Its Turkish equivalent is network address translation. With this system, devices with different network addresses can connect to the network using a single IP address. The system also ensures that other IPs are kept secret. With this mechanism, hackers who want to carry out cyber attacks via IP addresses cannot achieve their goal. NAT is similar to a proxy system because it is a system between a group of computers and an external network.
