Compare Cayosoft Guardian vs. Quest Change Auditor

Your Active Directory (AD) or Azure Active Directory (Azure AD) holds essential user identities that are critical for maintaining seamless business operations. The corruption of your Active Directory, whether due to harmful actions like cyberattacks and malware or errors such as accidental deletions and misconfigurations, can severely disrupt your business and lead to expensive downtime that may extend for hours, days, or even weeks. To address these challenges, Cayosoft Guardian was developed to simplify the security of hybrid Active Directory by integrating threat detection, monitoring, and recovery into one all-encompassing solution. This tool continuously observes directories and services, enabling you to identify suspicious changes and swiftly revert any unwanted modifications made to both objects and settings. It operates across on-premises AD, hybrid AD, Azure AD, Office 365, Microsoft Teams, and Exchange Online, all managed from Cayosoft Guardian’s singular, cohesive console. With this capability, businesses can enhance their resilience against potential disruptions and maintain operational continuity more effectively.

Quest Change Auditor is a real-time security auditing and threat monitoring solution for Active Directory and broader hybrid Microsoft environments. It monitors configuration changes, administrator actions, user activity, authentication events, and other security-relevant changes across on-premises and cloud systems. Supported environments include Active Directory, Azure AD, Office 365, Windows Server, Exchange, SQL Server, network-attached storage, SharePoint, and OneDrive for Business. Change Auditor detects indicators of compromise and suspicious activity while monitoring lateral movement and post-breach actions across systems such as file servers, Exchange, and Office 365. Threat prevention capabilities can block attackers from modifying critical groups, Group Policy settings and links, sensitive mailboxes, or extracting the Active Directory database to obtain credentials. The platform also identifies common Kerberos authentication vulnerabilities associated with Golden Ticket and Pass-the-Ticket attacks. Normalized audit records convert system activity into readable who, what, when, where, and workstation information together with before-and-after values. Threat timelines and related-event searches help investigators understand how individual changes connect with other security activity across the Microsoft environment. Change Auditor can integrate detailed activity logs with SIEM platforms such as Microsoft Sentinel, Splunk, ArcSight, and QRadar and can generate reports supporting compliance requirements including GDPR, PCI DSS, HIPAA, SOX, FISMA/NIST, and GLBA.
