Firewall is a system that monitors the incoming and outcoming traffic on your webiste. Firewall follows the security protocols and if it is met then only it passes the data to you. Basically, it partions between the trutsed internal network and untrusted external network.
Firewall is very important for any kind of online business and hence is important for your website.
As it blocks the suspicious activity, data theft and proactively protects the website from the cyber frauds.

Firewall is a security system that uses predetermined protocols that control the traffic coming or going out of your network.
It is always better to have firewall security for your website as it acts as a gate that keeps the malware outside your website.

A network security system that monitors as well as controls all the incoming and outgoing traffic on your website based on some security rules, it is called as a firewall.

Basically, a computer firewall is a software program that secures an unauthorized access to or from a private network.

The work of a firewall is to isolate your computer from the Internet using a "wall of code" that examines each individual "packet" of data as it arrives at either side of it— inbound to or outbound from your computer — to check whether it should be allowed to pass or should be blocked.

A firewall is a software or hardware device that appears as a filter for data entering or leaving a network or computer. It is designed to prevent unauthorized access enter to a private network.
In simple terms, a firewall is a security guard that determines who enters or exits a building. A firewall operates by preventing or restricting network ports. Firewalls are basically used to help block unauthorized access to both public and personal networks.

A firewall is software used to maintain the security of a private network. Firewalls block unauthorized access to or from private networks and are often employed to prevent unauthorized Web users or illicit software from gaining access to private networks connected to the Internet. A firewall may be implemented using hardware, software, or a combination of both.

A firewall is recognized as the first line of defense in securing sensitive information. For better safety, the data can be encrypted.

Types of the firewall are as follows:-

  • Packet filtering firewalls.
  • Circuit-level gateways.
  • Stateful inspection firewalls.
  • Application-level gateways.
  • Next-gen firewalls.

Personally, I would recommend you for security reasons you need to install a firewall for your website.

The firewall prevents the unauthorized access coming or going from a network. It can be implemented either on hardware, software or a combination of both to access the internet with the security. Thus, I think, it would always be a safer way to save your online business with a firewall.

It is a hardware deployed in tune with the web server or server plugin that directly runs on the web servers.
