What is Microsoft Defender for Endpoint?

Microsoft Defender for Endpoint, formerly known as Microsoft Defender Advanced Threat Protection (ATP), is a comprehensive enterprise endpoint security platform designed to help enterprises prevent, detect, investigate, and respond to advanced threats. This evolved version of what was initially a traditional antivirus software has expanded its capabilities to offer a full spectrum of endpoint security solutions, integrating seamlessly with other Microsoft security products.

Definition and Core Functionalities

Defender for Endpoint is a robust endpoint security solution that provides proactive threat prevention, post-breach detection, automated investigation, and response capabilities. It uses endpoint behavioral sensors that collect and process behavioral signals from the operating system, which then translates this data into insights, detections, and recommended responses to advanced threats.

Evolution of the Software

From its origin as a standard antivirus product, Defender for Endpoint has transformed into a sophisticated endpoint security solution. This evolution addresses a broader range of cybersecurity threats more intelligently and efficiently, with capabilities far exceeding traditional antivirus products.
