About

CyberArk Machine Identity Security provides comprehensive protection for all machine identities, including secrets, certificates, workload identities, and SSH keys. The platform offers centralized visibility and scalable automation to secure these non-human identities throughout their lifecycle. Designed to help organizations reduce risk and maintain resilience, CyberArk ensures secure machine identity management across on-premises, cloud, and hybrid environments.

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.
