Quest Identity Defense

Quest Identity Defense is an agentic AI-powered identity security platform that helps organizations reduce risk, stop attacks, and strengthen resilience across hybrid Active Directory and Microsoft Entra ID environments. As identity becomes the primary attack surface for cyberattacks, organizations need comprehensive visibility and protection across both human and non-human identities. Identity Defense delivers continuous insight into identity posture, privileged access, Tier 0 assets, and potential attack paths, helping security teams identify and remediate vulnerabilities before they can be exploited. Built specifically for hybrid identity environments, Identity Defense combines security-grade visibility, deep auditing, proactive protection and containment, and AI-driven threat detection in a unified platform. Security teams can benchmark configurations against industry best practices, uncover privilege risks, investigate suspicious activity, and gain the context needed to respond to threats faster. Human-readable auditing provides detailed visibility into identity changes, helping organizations strengthen security operations, support compliance initiatives, and improve overall governance. Identity Defense goes beyond detection by helping organizations actively safeguard critical identity infrastructure. Its unique object protection prevents critical Tier 0 misconfiguration, rather than having to rollback after changes. Agentic AI defense and Shields Up containment capabilities allow teams to autonomously freeze changes to Tier 0 and other high-value assets during a suspected attack, disrupting lateral movement, limiting persistence techniques, and reducing the potential blast radius of identity-based threats. By combining visibility, protection, detection, response, and compliance readiness, Quest Identity Defense helps organizations secure Active Directory and Entra ID, reduce identity risk, strengthen cyber resilience, and respond confidently to evolving threats across the complete identity security lifecycle. The platform also helps organizations align identity security operations with industry best practices while improving readiness for audits, compliance reviews, and incident response efforts.
