What is a Firewall?

Why is a Firewall Necessary?

Today's rapidly evolving digital transformation has made it imperative for all companies to be part of this transformation. This development and transformation is called a firewall, which are security wall systems that prevent unauthorized individuals from accessing sensitive company or user data from inside or outside the company over internet networks.

It is a security wall system that controls incoming and outgoing traffic within internet network traffic according to pre-determined protocols, ensuring that it reaches its intended destinations or prevents unwanted access. Firewall systems, known as security walls, ensure network security by controlling internal and external network traffic. Which security wall system a company uses varies. However, in addition to controlling all incoming and outgoing network traffic, it also filters it through specific filters, stopping all harmful and malicious activities within the network traffic.

Is Firewall Hardware-Based or Software-Based?

In today's developing digital age, companies must prevent any cyberattacks that may occur on internal and external computer systems. Therefore, they need firewall systems. Firewall systems perform the task of ensuring network security by controlling all traffic coming through internal and external network traffic. Thus, all internal or external computers and other devices will be protected. Firewall, known as a security wall system, can be hardware-based or software-based. Software-based security wall systems are generally installed on servers and operating systems. Hardware-based security wall systems, on the other hand, are systems where firewall devices operate on specialized hardware. Thanks to the rapidly developing technology today, firewall devices are developed to offer integrated solutions.
