What is Windows Firewall in Windows 11?

On Windows 11, the firewall is managed through Windows Security and Windows Defender Firewall:

• Windows Security = basic on/off, network status, quick controls.
• Windows Defender Firewall with Advanced Security (wf.msc) = detailed inbound/outbound rules, ports, etc.

Below are different ways to open it.

What You See Inside the Firewall Windows

A. Windows Security – Firewall & network protection

Here you can:

• See current network profiles:
  • Domain network – usually corporate network with AD/Entra join.
  • Private network – trusted home network.
  • Public network – public Wi-Fi, hotels, etc.
• Check if firewall is On or Off for each profile.
• Click Allow an app through firewall (opens the classic UI).

  • Traffic coming into your PC.
  • Rules decide which apps/ports are allowed or blocked from the outside.
• Outbound Rules
  • Traffic going out from your PC to the network/internet.
• Connection Security Rules
  • Advanced rules for IPsec, secure tunnels, etc.
• Monitoring
  • View active rules and security associations.

Quick Troubleshooting Tips

If you can’t find or open the firewall:

1. Search spelling
   • Make sure you typed firewall, Windows Security, or wf.msc correctly.
2. Check user permissions
   • Some advanced options require Administrator rights.
   • Try right-clicking Windows Terminal or Command Prompt and choose Run as administrator.
3. Managed devices (work/school)
   • If your device is joined to a company (Intune, Group Policy, etc.),
     • Firewall settings might be locked by your IT admin.
     • You may see messages like “Some settings are managed by your organization.”
4. Firewall service disabled
   • Rare, but if someone disabled the “Windows Defender Firewall” service, the app may not work correctly.
   • In that case, ask an admin to check services.
