This confidence in security measures can lead to increased innovation and efficiency as organizations explore the full potential of cloud computing.

ManageEngine Vulnerability Manager Plus is an enterprise vulnerability management and compliance solution that helps IT and security teams detect, prioritize, and remediate security risks across their entire network from a single console. Unpatched endpoints and security misconfigurations remain the most common entry points for cyberattacks. With the CVE database crossing 350,000 recorded vulnerabilities and attackers increasingly using AI to identify and exploit weaknesses faster, IT teams can no longer rely on periodic scans and manual remediation workflows to keep their environments secure. Vulnerability Manager Plus addresses this by delivering continuous, real-time visibility into every endpoint across the network including desktops, laptops, servers, virtual machines, DMZ servers, and network devices across local offices, remote branches, and roaming environments. AI-powered threat intelligence assigns risk scores using CVSS severity, exploit availability, vulnerability age, and active attack trends so teams can focus their remediation efforts where they matter most. Unlike most vulnerability management platforms, Vulnerability Manager Plus includes built-in patch management at no additional cost. It automates patch deployment across Windows, macOS, Linux, and 1,500+ third-party applications with customizable deployment policies, test-and-approve workflows, and automatic rollback. For zero-day vulnerabilities where no vendor patch is available, pre-built scripts can be deployed immediately to contain risk while awaiting a fix. Beyond patching, it continuously detects security misconfigurations, hardens web servers, audits high-risk software, and automates compliance audits against CIS, NIST, and UK Cyber Essentials. Available as cloud or on-premises in Free, Professional, and Enterprise editions.
