About

Quest Identity Defense, formerly Security Guardian, is an agentic AI-powered identity security solution for protecting hybrid Active Directory and Microsoft Entra ID environments. The platform continuously monitors human and non-human identities to identify risks, anomalous behavior, privilege exposures, and vulnerabilities involving critical Tier 0 assets. Identity posture management benchmarks AD and Entra ID configurations against industry best practices and provides remediation guidance for discovered security weaknesses. Proactive object protection prevents unauthorized or risky changes to critical objects, while Shields Up and agentic AI capabilities can automatically contain active attacks and block lateral movement. Deep monitoring and human-readable auditing provide information about who changed an identity asset, what was changed, when and where the change occurred, and which workstation was involved.

About

Tenable One Identity Exposure is an identity security solution designed to help organizations find and close identity-based attack paths before attackers exploit them. The platform provides visibility into identity hygiene across Active Directory and Entra ID environments. It helps teams unify identity inventory, map attack paths, harden security, and reduce risk across hybrid identity systems. Tenable One Identity Exposure supports identity security posture management by helping organizations understand how misconfigurations, risky permissions, and identity weaknesses can create breach opportunities. As part of the Tenable One exposure management platform, it connects identity risk with broader security visibility across the attack surface. Tenable One Identity Exposure is built to help security teams strengthen identity defenses, reduce attack chains, and improve protection against active threats.
