## About Quest Identity Defense
Quest Identity Defense (previously known as Security Guardian) is an AI-powered, hybrid Active Directory security solution that continuously identifies identity risk, blocks unauthorized changes to critical Tier 0 assets, and instantly contains attacks before they spread. With clear visibility and observability across human and non-human identities, organizations can investigate, respond, and remediate threats with simplicity and speed. Identity is now the primary attack surface, yet most organizations lack the visibility and protection needed to defend it. Quest Identity Defense gives continuous insight into identity posture across Active Directory and Entra ID, benchmarking configurations against industry best practices and surfacing Tier 0 exposures, privilege risk, and non-human identity vulnerabilities before attackers exploit them. With dynamic Shields Up containment and proactive object protection, teams can stop attacks mid-flight and freeze changes to crown-jewel assets to limit blast radius. Deep Active Directory auditing and AI-driven insights empower teams to cut through alert fatigue, detect and investigate threats faster, and improve mean time to respond (MTTR) by 44%.
