Securing identity is crucial for maintaining business continuity, particularly in hybrid environments with Active Directory and Entra ID. With Active Directory security being a top priority, organizations must consider that Forrester reports downtime costs as high as $730K per hour, and with 80% of breaches involving compromised identities, these systems have become prime targets. Security Guardian mitigates these risks and by using Machine Learning to establish behavioral baselines, detecting unusual patterns like spikes in account lockouts, failed sign-ins, and permission changes. Through integration with Microsoft Security Copilot, it extends powerful and seamless ITDR functionality across your hybrid AD environment.

Security Guardian FAQs

While Microsoft Defender for Identity (MDI) provides robust security, Security Guardian offers additional specialized features that enhance Active Directory security and protection for your environment. Security Guardian alerts on specific attacker tools, techniques, and procedures (TTPs) within Active Directory, ensuring comprehensive threat detection. It enforces adherence to Privilege Account Management policies by hindering implicit relationships, especially concerning Tier 0 objects. Security Guardian automatically categorizes these critical objects and monitors any drifts from their known state. Furthermore, Security Guardian proactively identifies, alerts on, and protects critical objects (including GPOs) from setting changes and database attacks. It also retains findings and audit data in compliance with retention requirements, ensuring thorough and compliant security management.

Additionally, Security Guardian integrates with MDI by forwarding its findings to Sentinel, which, in turn, sends signal data to Microsoft Defender. * MDI to Sentinel forwarding requires special Microsoft licensing
