Compare Microsoft Entra ID Protection vs. Quest Identity Defense

Microsoft Entra ID Protection leverages sophisticated machine learning techniques to detect sign-in threats and atypical user activities, enabling it to block, challenge, limit, or permit access as necessary. By implementing risk-based adaptive access policies, organizations can bolster their defenses against potential malicious intrusions. In addition, it is crucial to protect sensitive access through robust authentication methods that provide high assurance. The system allows for the export of intelligence to any Microsoft or third-party security information and event management (SIEM) systems, as well as extended detection and response (XDR) tools, facilitating deeper investigations into security incidents. Users can enhance their identity security by reviewing a comprehensive overview of thwarted identity attacks and prevalent attack patterns via an intuitive dashboard. This solution ensures secure access for any identity, from any location, to any resource, whether in the cloud or on-premises, thereby promoting a seamless and secure user experience. Ultimately, the integration of these features fosters a more resilient security posture for organizations.

Quest Identity Defense, previously known as Security Guardian, is a hybrid identity security platform for protecting Active Directory and Microsoft Entra ID from identity-based threats. The platform continuously observes human and non-human identities to identify Tier 0 exposures, privileged attack paths, risky configurations, anomalous behavior, and other identity vulnerabilities. Identity posture management compares AD and Entra ID configurations with security best practices and provides guidance for remediating identified weaknesses. Proactive object protection helps prevent critical Tier 0 assets from being improperly changed or compromised rather than relying exclusively on rollback after an incident. Quest's Shields Up functionality and agentic AI defense capabilities can automatically freeze at-risk users or critical objects, contain active threats, and limit attacker lateral movement. Continuous anomaly monitoring and detailed auditing show who changed what, when and where the activity occurred, and the workstation from which a change originated. AI-driven analysis converts identity telemetry into security insights and remediation guidance intended to help teams investigate threats and respond more quickly. A flexible API enables organizations to integrate Identity Defense information with existing security tools and custom workflows, while the platform is also designed to support audit and compliance requirements. Quest Identity Defense covers identity security functions across the Identify, Protect, Detect, Respond, Recover, and Govern pillars of the NIST Cybersecurity Framework and is FedRAMP High authorized.
