Quest Software

Quest Software is a U.S.-based enterprise software vendor focused on systems management, identity and access management, database management, data protection, migration, and Microsoft platform administration. The company is widely known for products such as NetVault Backup, KACE, PowerGUI, and tools for Active Directory, PKI, and coexistence or migration scenarios involving Microsoft and legacy collaboration platforms. Quest has operated for decades in the enterprise IT market and serves organizations ranging from mid-sized businesses to large enterprises and public-sector environments.

From a cybersecurity perspective, Quest Software is relevant both as a software supplier and as a vendor whose products have been the subject of multiple publicly disclosed vulnerabilities. Quest NetVault Backup has had numerous high-severity issues disclosed in 2026, including SQL injection, command injection, authentication bypass, and cross-site scripting flaws affecting multiple components and creating potential paths to remote code execution. Quest Coexistence Manager for Notes was also reported vulnerable in 2025 to an HTTP request smuggling issue in its Free/Busy Connector. These disclosures make patch management and exposure assessment for Quest products particularly important in enterprise environments.

Quest has also appeared in the threat landscape as a victim organization in reporting on REvil ransomware activity. In addition, some Quest products and tooling have surfaced in intrusion reporting and administrative tradecraft, including PowerGUI in malware delivery chains and Quest administrative tools in enterprise identity operations. Overall, Quest Software is a significant enterprise infrastructure software provider with notable security relevance due to both product exposure and its presence in broader cyber incident reporting.
