Windows Firewall: How to block Internet access for a program?

Learn the simple steps to block or remove internet connection for some particular application running on Windows 11/10/7 using in-built “Windows Defender Firewall with Advanced Security”.

Well, there are many situations in which we need to revoke permission of some application to access the Internet connection on the system. If that is the situation, then the trick given in the article will help you to do that without turning off the Internet access for the whole computer.

What Windows Firewall?

It is a security layer or tool offered by Microsoft in its Windows OS to enhance security. It helps to protect the system against unwanted connections from the internet by monitoring incoming and outgoing network traffic. And on the basis of pre-defined or custom rules, it allows or blocks specific traffic.

 

Why should I block a connection?

The reason depends upon your needs, however, generally, if you have some confidential information within the software and you don’t want it to access the internet or outside network then it is worth isolating the program. Due to the data lock, no data can be sent to the Internet and the program is a safe haven.
