Endpoint devices are the entry points through which potential cyber criminals can gain access to your organization’s network. Go on a wrong website or click on a malicious email attachment, and that could be the entry point into your system. Vulnerabilities could include outdated systems, security misconfigurations, weak passwords, or lack of proper security software.
Microsoft 365 Endpoint Security
Microsoft 365 provides a range of tools to help secure endpoint devices. These tools assess and respond to endpoint vulnerabilities using a multi-faceted approach, including Identity and Access Management, Threat Protection, Information Protection, and Security Management.
- Identity and Access Management: This includes tools like Azure Active Directory (AD) and Conditional Access Policies, which enforce strong identity verification and limit access based on user activity, location and device status.
- Threat Protection: This refers to features like Microsoft Defender for Endpoint and Office 365 Advanced Threat Protection. They provide robust mechanisms that detect, prevent, investigate, and respond to potential threats.
- Information Protection: Tools like Data Loss Prevention (DLP) policies, Windows Information Protection, and Azure Information Protection help classify, protect, and monitor sensitive data.
