Description

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.

Description

Tenable One Identity Exposure is an identity exposure management solution that helps organizations secure Active Directory, Entra ID, and hybrid identity environments. The platform gives security teams visibility into identity hygiene so they can detect weaknesses, understand attack paths, and take action before attackers exploit identity-based risks. It helps teams unify identity inventory, map paths that could lead to compromise, and harden security across users, permissions, and configurations. Tenable One Identity Exposure supports identity security posture management by identifying the identity conditions that can enable lateral movement, privilege escalation, and breach activity. The solution helps organizations move beyond point-in-time audits by continuously monitoring identity exposure across the attack surface. It also provides insights such as the Identity Asset Exposure Score to help teams understand and prioritize identity risk. As part of Tenable One, it brings identity findings into a unified exposure management platform that also supports cloud, vulnerability, OT, and broader attack surface risk. Security teams can use the platform to break attack chains, improve identity governance, and reduce the likelihood of identity-driven breaches. Tenable One Identity Exposure is designed for organizations that need stronger visibility, faster action, and better control over identity-related cyber risk.
