Critical questions to ask when evaluating AD vendors

Does the solution provide full visibility and control of Tier 0 assets?

Security Guardian offers unparalleled clarity into your hybrid AD environment, automatically identifying and monitoring Tier 0 assets in both AD and Entra ID. Be cautious of vendors who fail to prioritize critical object protection, as this can leave your organization vulnerable to compromise.

Does the solution protect against misconfigurations and GPO compromises?

Security Guardian empowers you to lock down critical objects, including GPOs, with precise control and effortless rollback capabilities. Be wary of solutions that offer limited or rollback-only recovery, as they may not fully safeguard your environment from unauthorized changes.

Can the solution integrate seamlessly with your existing security stack?

Security Guardian integrates effortlessly with Microsoft Security Copilot, Sentinel, and third-party SIEM tools like Splunk, forwarding critical findings to ensure centralized visibility and enhanced collaboration. Looking for solutions that not only work within your ecosystem but also enhance your cross-product insights can be key to increasing productivity and filling in security gaps.

Does the solution bridge cybersecurity talent gaps?

With its Microsoft Security Copilot plugin, Security Guardian enhances your team’s capabilities through AI-driven insights, natural language reporting, and guided remediation, supplementing expertise during talent shortages.

How does the solution handle detection of hacker tactics and anomalies?

Security Guardian continuously monitors for anomalous activities, such as permission changes and account lockouts, using Azure AI and Machine Learning to identify hacker TTPs (Tactics, Techniques, and Procedures) early. This minimizes false positives and ensures faster response times.

Does the solution bridge the identity security gap left by EDR, NDR, and XDR?

While EDR and NDR focus on endpoints and network traffic, and XDR integrates their signals for unified visibility, many solutions fail to address identity-specific vulnerabilities. Security Guardian fills this critical gap by delivering robust Identity Threat Detection and Response (ITDR) capabilities tailored for protecting Active Directory and Entra ID. With focused protection for identity infrastructure, it complements your existing EDR and NDR solutions, ensuring holistic security for your hybrid AD environment.

How comfortable are you with the vendor’s support SLA times?

Quest offers award-winning technical support with 24/7/365 availability, 1-hour response times for Level 1 cases, and a Premier Support option to reduce SLA times by half.

What are other vendors doing to secure their software supply chain?

Quest is extremely mindful of the increased attacks on supply chains and takes great lengths to protect it, with mature supply chain risk management practices and an airgap-secured assembly process that exceeds industry standards. Quest performs no development in countries of security concern.

While other vendors may advertise being cyber-first, be sure to validate supply chain risk management practices, and ensure that your leadership is comfortable with the locations/countries where development is performed.
