What is Tenable One Identity Exposure?

Tenable One Identity Exposure is an identity security posture management and exposure management solution built to help organizations reduce identity-driven cyber risk. The platform focuses on visibility and protection for Active Directory, Entra ID, and hybrid identity environments where misconfigurations, risky permissions, and attack paths can create serious breach opportunities. It helps teams unify identity inventory, map attack paths, identify identity hygiene issues, and harden security before attackers can move through the environment. Tenable One Identity Exposure is designed around the reality that identity is central to modern breaches, making it critical for organizations to understand who has access, how permissions are configured, and where dangerous paths exist. The platform helps security teams discover identity weaknesses that can lead to privilege escalation, lateral movement, and active exploitation. It supports continuous identity security posture management rather than relying only on occasional audits or manual reviews. Features such as attack path mapping and Identity Asset Exposure Score help teams prioritize identity risks based on exposure and potential impact. As part of Tenable One, the solution connects identity risk with broader exposure data across cloud, OT, vulnerability management, and attack surface management. This unified context helps organizations understand how identity weaknesses interact with other cyber risks across the enterprise. Tenable One Identity Exposure also supports related strategies such as least privilege, hybrid identity governance, active threat defense, and identity-aware remediation planning. The platform helps enterprises strengthen identity defenses, break attack chains, and reduce the chance that attackers can use compromised identities to reach critical systems.

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.
