Defend Against Threats with Microsoft Defender for Endpoint.

Updated: Dec 12, 2023

1.1. Improving Organizational Security with Microsoft Defender for Endpoint

Introduction

Organizations are increasingly relying on cloud apps to streamline operations, facilitate collaboration, and spur creativity in today's quickly changing digital landscape. The advantages of cloud computing come with some serious security challenges, for companies of all sizes and in all sectors, ensuring the confidentiality, integrity, and availability of sensitive data across numerous cloud apps has become of utmost important and its security is a big concern.

Microsoft Defender is a family of security products and services that protect devices, identities, applications, data, and workloads from known and emerging threats. It is a unified pre- and post-breach enterprise defense suite that natively coordinates detection, prevention, investigation, and response across endpoints, identities, email, and applications to provide integrated protection against sophisticated attacks.

Endpoint behavioral sensors: Embedded in Windows 10, these sensors collect and process behavioral signals from the operating system and send this sensor data to your private, isolated, cloud instance of Microsoft Defender for Endpoint.

Cloud security analytics: Leveraging big-data, device learning, and unique Microsoft optics across the Windows ecosystem, enterprise cloud products (such as Office 365), and online assets, behavioral signals are translated into insights, detections, and recommended responses to advanced threats.

Threat intelligence: Generated by Microsoft hunters, security teams, and augmented by threat intelligence provided by partners, threat intelligence enables Defender for Endpoint to identify attacker tools, techniques, and procedures, and generate alerts when they are observed in collected sensor data.
