Windows 10 comes with several security features to keep your device and data protected against unauthorized access, malware, and other attacks, including a powerful built-in firewall, known as Windows Defender Firewall.
Although the Windows Defender Firewall does a pretty good job managing which applications and features are allowed to connect through the network, sometimes you may need to allow or deny an apps manually.
How to allow apps through the firewall on Windows 10
To allow an app through the Windows 10 firewall, use these steps:
Open Windows Security.
Click on Firewall & network protection.
Click the Allow an app through firewall link.
Click the Change settings button.
Check the app or feature you want to allow through the firewall.Quick tip: If the app isn’t on the list, click the Allow another app button to locate the application you want to allow.
Check on which type of networks an app can access the network:
- Private — Allows the app access to the network at home or work.
- Public — Allows the app access to the network at a public place, such as on a coffee shop.
Click the OK button.
Once you complete the steps, the app will now freely access the network.
If you want to block an app through the firewall, you can follow the same instructions, but on step No. 5, make sure to clear the check mark for the app or feature you want to deny access to the network.
This guide focuses to configure the Windows 10 firewall, but in the case that you have another security solution, make sure to check your vendor support website for specific instructions.
