Protect on-premises and hybrid environments with advanced threat detection and seamless integration
Our Active Directory implementation is a hybrid one. The advanced threat protection is one of the strengths of Microsoft Defender for Identity, as it utilizes user and entity analytics and can detect indicative attacks. It identifies lateral movements, privilege escalations, and alerts on potential attacks. The tool is also used for security posture assessment. The seamless integration with other Microsoft solutions within our Microsoft-centric environment is also a major advantage.
