What is Windows Firewall? Is it good enough? How to enable/disable it?

The Windows Firewall is an in-built solution from Windows to monitor and control all incoming and outgoing network traffic on your computer. It is a very well developed system which works silently in the background and needs no separate installation.

First, we’re going to talk about why we require Windows Firewall. It is very effective and does not constantly annoy by too many pop-ups. It runs seamlessly in the background and has seen massive improvements over several OS updates. The Windows Firewall is more than enough to protect your network during day-to-day use.

This firewall made its first debut with Windows XP and has come a long way since. It monitors all network activity that is accessed by applications or programs and is also very flexible. The user can choose from various levels of security according to preference.

The Windows Firewall is primarily required to keep your system safe from any kind of incoming malware through your network or the internet. It also blocks any sort of unauthorised access to your PC too.

It monitors both inbound and outbound network traffic and instantly reports if any suspicious data is detected.

The Windows Firewall is deeply integrated with the OS as it is developed specifically for Windows and hence works seamlessly. It has many good features including one where you can Allow or Deny networks access to every app or program individually.
