What is Quest Identity Defense?

Quest Identity Defense, formerly called Security Guardian, is an agentic AI-powered identity threat detection and security platform for hybrid Active Directory and Microsoft Entra ID environments. It provides continuous visibility and observability across both human and non-human identities to help organizations identify and investigate identity-related security risks. The platform detects Tier 0 exposures, privileged attack paths, risky configurations, anomalous activity, and vulnerabilities associated with workload and other non-human identities. Identity posture management benchmarks Active Directory and Entra ID configurations against industry best practices and provides remediation guidance for identified vulnerabilities and compromises. Proactive object protection is designed to prevent unauthorized or dangerous changes to critical Tier 0 objects before those changes result in compromise. During an active incident, Shields Up and agentic AI defense capabilities can automatically freeze vulnerable users or objects, stop attacks in progress, and limit lateral movement through the environment. Deep monitoring and auditing provide human-readable records showing who performed a change, what was modified, when and where the event occurred, and which workstation was involved. Integrated AI analyzes identity telemetry and converts it into security insights and remediation recommendations that can help security teams reduce investigation and response time. Quest states that Identity Defense can improve mean time to respond by 44% by helping teams reduce alert fatigue and move more quickly from detection to investigation and containment. The platform includes a flexible API for extending identity security data into existing security ecosystems and custom workflows, while its auditing capabilities can also help organizations improve compliance readiness.
