Windows defender is a simple way to protect your digital life and all of your devices. It comes with your Microsoft 365 Family, or Personal, subscription at no extra cost.

Firstly, preventing malware

Malware refers to malicious software which can steal or damage your personal data such as files, photos, or messages. This malware may also track or spy on you, steal your money, or use your device to cause other mischiefs like attacking other people.

On platforms like Windows, Mac, and Android, Microsoft Defender can check files or apps you download and install, as well as run scans of files already on your system to spot any malware that may threaten your device.

Note: Stay up-to-date and install the latest updates on all your devices and apps (especially browsers) to help prevent malware.

In the event that you have a non-Microsoft antimalware product installed, such as Norton or BitDefender, Microsoft Defender can work alongside it.

Secondly, web protection

Most digital attacks we see are through harmful websites that try to trick you into revealing personal information—such as usernames and passwords, credit cards, or other account information—or installing malware on your system.

On platforms like windows, iOS, and Android, Microsoft Defender will check links that you (or an app on your device) open to try and spot any that may be dangerous.

In case it finds a harmful link, it’ll block it and let you know.

Thirdly, identity theft monitoring

Microsoft partnered with Experian® to bring world-class identity theft monitoring to Microsoft Defender. Identity theft monitoring allows you to monitor your own identity details, as well as your family’s, for breaches on both the public internet and the dark web.

Provided defender spots your personal details in a breach, you’ll receive an alert and a detailed breach report telling you exactly what data was found and where. Then, you’ll get recommendations on what to do right away to address the situation, details on how this might have happened, information on the possible risks, and tips on how to reduce the chances of it happening again.

Additionally, you also get 24/7 phone access to a team of highly skilled identity theft professionals who can guide you through the process of addressing the breached details or provide full-service identity restoration services in the event an identity thief is using your personal details to commit fraud.

Lastly, adding other devices

Furthermore, you can add up to 4 additional devices (for a total of 5 per person) to your Microsoft Defender account by installing the app on your other devices and signing in using the same personal Microsoft account.

The added devices will appear on your Microsoft Defender dashboard so you can see the security status of all your devices in one place.
