Windows 11 helps protect your computer from viruses and other threats by using security software. Your device may use Microsoft Defender (which is free and already built into Windows) or another security program you installed.

This guide will show you how to check which security software is protecting your device right now by looking inside the Windows Security app.

What Are Security Providers?

Security providers are programs that help keep your PC safe. These include:

• Antivirus — stops viruses and malware
• Firewall — blocks unauthorized access to your computer
• Web Protection — helps keep you safe while browsing the internet

If you don’t have a third-party antivirus program (one you installed yourself), Microsoft Defender will protect you automatically.

How to Check Your Security Providers in Windows 11

Follow these simple steps to find out which security software is running on your device:

1. Open the Windows Security app:
   
   Click the Start menu (the Windows icon at the bottom-left of your screen), then type Windows Security in the search box.
   
   When you see Windows Security in the results, click it to open the app.

2. In the Windows Security app, look for the Settings icon at the bottom left side of the main page called Security at a glance. Click on it.

3. In the Settings page, find the Security providers section. Click the Manage providers link.

4. Now, you will see a list showing your security providers for:

• Antivirus
• Firewall
• Web Protection

Usually, if you don’t have another security program, Microsoft Defender will be listed as your provider for all three.

Summary

• The Security Providers page in Windows Security shows what programs are protecting your PC.
• To open it, start the Windows Security app, click Settings, then Manage providers.
• You’ll see your antivirus, firewall, and web protection providers listed.
• By default, Microsoft Defender covers all these if you don’t have other security software installed.

Knowing this helps you understand how your Windows 11 PC stays safe from threats.
