Compare Quest Identity Defense vs. Rezonate

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.

Rezonate automatically detects and corrects access configurations, risky activity, and weak security practices across all your identity providers and IaaS, reducing your identity risk. Rezonate continually synthesizes all of your cloud applications, resources, as well as your human- and machine identities. It gives you a single identity storyline that provides a comprehensive view of all your access risk and identity. Rezonate's Identity Storyline goes far beyond the traditional graph views. It tells you the story behind every identity, threat and exposure so that you can confidently identify, prioritize, and take action to eliminate access risks. Identity Storyline provides a detailed explanation of every threat, exposure, or active threat that is detected and how it got there, as well as the potential consequences. You can now see every activity and change across your cloud identity attack surface in real-time, beyond the periodic configuration scans.
