ADAudit Plus delivers stronger auditing at a lower price than Quest Auditor

Quest Auditor is licensed per user, so costs rise as you add users, even without adding servers. In contrast, ADAudit Plus is licensed per server, helping you stay within budget even as user numbers grow.
Both ADAudit Plus and Quest Auditor offer comparable auditing capabilities. However, ADAudit Plus goes further with features like GPO misconfiguration detection; risky configuration detection for Azure, AWS, and GCP; broader NAS device support including Synology, Hitachi, Huawei, Amazon FSx, NetApp ONTAP-AWS, QNAP, and Azure Files; agentless log collection; and incident response.
