Tenable Identity Exposure

Tenable Identity Exposure (formerly Tenable.ad / Alsid) is an enterprise identity security platform engineered to discover, investigate, and remediate Active Directory (AD) and Microsoft Entra ID vulnerabilities, misconfigurations, and active attacks in real time. Because Active Directory serves as the primary authentication and authorization backbone for over 90% of global enterprises, it represents the primary target for cyber attackers seeking privilege escalation and domain dominance. Tenable Identity Exposure protects identity infrastructure without requiring agents on domain controllers or privileged domain admin credentials.

The platform continuously analyzes Active Directory replication streams to detect security drift, misconfigurations, and active attacks as they occur. Key technical capabilities include automated discovery of AD weaknesses (such as Kerberoasting, AS-REP roasting, DCSync vulnerabilities, unconstrained delegation, and shadow administrators), attack path visualization that reveals step-by-step lateral movement routes to Domain Admin status, and real-time detection of live attacks (such as Golden Ticket generation, DCShadow, and brute-force attacks). By alerting security teams to identity risks before attacks occur and guiding step-by-step remediation, Tenable Identity Exposure hardens the core enterprise identity perimeter.

Tenable Identity Exposure integrates with Tenable One, Microsoft Sentinel, Splunk, IBM QRadar, ServiceNow, and enterprise SIEM/SOAR platforms. Core enterprise use cases include preventing ransomware groups from gaining Domain Admin privileges, hardening hybrid Active Directory architectures, auditing trust relationships between AD domains, and meeting regulatory identity governance requirements. Tenable Identity Exposure delivers real-time identity defense, agentless architecture, and proactive Active Directory hardening.
