In our ongoing series, SecureSky aims to provide details about the Microsoft Defender technologies suite.

The Evolution of Microsoft Defender

Initially known as Microsoft's antivirus solution, the "Defender" branding has evolved. It now encompasses a broad range of security products under the "Defender for ..." umbrella. This suite includes cutting-edge XDR (Extended Detection and Response) technologies designed to safeguard against threats targeting identities, endpoints, applications, emails, IoT devices, infrastructure, and cloud platforms.

While the unified branding simplifies the product suite's identity, it presents challenges. Users often find themselves navigating through the myriad of "Defender for ..." offerings, trying to understand their functionalities, how they integrate with Microsoft's ecosystem and third-party solutions, and their acquisition process.
