Microsoft Defender is Microsoft’s dedicated security application for individuals and families, rolling device protection, identity theft monitoring, and credit alerts into one easy-to-manage dashboard. Unlike the classic Windows Security utility built into Windows, this application is an extension available exclusively to those with an active Microsoft 365 Personal or Family subscription. 

Microsoft Defender simplifies online safety by providing a cohesive security experience across multiple platforms. It offers multi-device, cross-platform protection for major operating systems, ensuring your digital life is safeguarded no matter what device you are using. Its focus on identity and credit monitoring makes it a robust, all-in-one package.

Cross-platform protection and identity safeguards 

Microsoft Defender excels at extending the trusted protection of Microsoft to all your devices. It complements the built-in Windows Security, while offering its own trusted antivirus and anti-phishing protection for various devices. Each person covered by the Microsoft 365 subscription can secure up to five devices simultaneously, making it an excellent choice for families managing a diverse collection of hardware, all monitored and updated from a single, unified interface

Beyond device protection, the application provides crucial safeguards for your personal information. It offers continuous scanning of threats to your identity and personal identifying information, helping to protect against hackers and scammers. The service includes credit monitoring with timely alerts and monthly reports, along with access to 24/7 identity theft restoration experts. With this application, you can manage your online safety and deal with threats without feeling overwhelmed.

Despite its comprehensive feature set, one noticeable drawback of the software is its strict paywall. Unlike a number of similar programs, such as AVG AntiVirus Free or the basic Windows Security features, it requires a premium Microsoft 365 subscription (Personal or Family) to activate and use. This mandatory subscription model effectively locks out users who prefer a one-time purchase or a standalone subscription for security only.
