How to Allow an App through Windows Firewall?
Windows Firewall helps protect your computer from unauthorized access, malware, and other security threats
Windows Firewall: It is a network security system designed to monitor and control incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between your computer and potential threats from the internet or other networks, helping to protect your system from unauthorized access and cyber-attacks. Windows Firewall was first introduced in Windows XP in 2001 as part of Service Pack 2 (SP2), released in August 2004. Initially named “Internet Connection Firewall,” it was rebranded to “Windows Firewall” and significantly enhanced in functionality and ease of use. Windows Firewall blocks apps by default to maintain a secure environment, and there may be instances where we trust an app and want to allow it through Windows Firewall. This article will cruise through the steps of How to Allow an App through Windows Firewall in Windows 11.
Key Steps:
- Go to Windows Securiy and then to Virus & Threat Protection.
- Navigate to Firewall & Network Protection.
- Click on Allow an App through firewall.
- Select the App that you want to allow.

- Scroll through the list of apps available, and locate the app that you want to allow through Windows Firewall.
- Once you find your app, you can find two check boxes next to it, Private and Public. Private networks are networks that you trust, such as your home or office network. Public networks are networks that you do not trust or not familiar with, such as a public Wi-Fi at a mall or airport. Choose accordingly.
- Finally, click OK to save the changes. Your selected app should now be allowed through Windows Firewall in Windows 11.
What are the Risks of allowing an app through Windows Firewall?
Allowing an app through Windows Firewall introduces several risks, such as unauthorized access and data leakage. If the app has security vulnerabilities or becomes compromised, attackers can exploit these weaknesses to gain unauthorized access to your system, potentially leading to data breaches. Additionally, allowing apps increases your network’s attack surface, providing more opportunities for malware to communicate with command-and-control servers, which can further spread infections or exfiltrate data. Furthermore, allowing unnecessary apps can consume network bandwidth and system resources, affecting overall performance.
When should an App be allowed?

There are three crucial considerations. Trusted Source, Specific need, and Proper Configuration.
- Ensure the app comes from a trusted source and is not malicious. Only allow apps that are necessary and verified to be safe.
- Allow the app through the firewall only if it specifically needs network access to function. Unnecessary allowances can create security risks.
- Configure the firewall to allow only the necessary types of traffic for the app. For example, allow specific ports, protocols, or IP addresses rather than a broad allowance.
Information on the Go!
The principle of “default deny” is a security best practice. It means that by default, all connections are blocked, and only those explicitly allowed are permitted. This minimizes the attack surface and enhances security.
Restore Firewalls to default in Windows 11:

- This option will remove Windows Defender Firewall settings that you have configured for all network locations. Please note that this might cause some apps to stop working.
Take away:
Windows Firewall blocks apps by default, even those from trusted sources, to maintain a high level of security and ensure that only necessary network communications are allowed. This approach helps maintain a secure computing environment and minimizes the risk of unauthorized access and data breaches. By being cautious and selective about which apps are allowed through Windows Firewall, you can minimize potential security risks and maintain a more secure network environment in Windows 11.
