Messageware Server Threat Guard (STG) Description
Messageware Server Threat Guard (STG) is a server security and health monitoring tool that runs directly on the server, performing all analysis locally without cloud components or external dependencies. STG provides real-time threat detection across Windows Servers, Exchange Servers, virtual machines, and cloud servers (AWS and Azure). It monitors key server components including the registry, startup items, file and virtual directory integrity, services, scheduled tasks, event logs, application stability, and WSUS. The product uses built-in integrity rules for Windows Server alongside "AutoLearn" generated baselines to detect unexpected or risky server changes. Threats are automatically categorized, allowing teams to configure alerts for high-priority detections only and reduce alert fatigue. Alerts are delivered in near-real time, and the product generates daily server health summaries and consolidated reports via dashboards. It can operate as a standalone solution or integrate with enterprise SIEMs to push data to centralized security operations. Deployment is designed to be rapid, with out-of-the-box server templates, automatically generated intelligent policies per server, and automated deployment support for multiple servers. The agent is described as lightweight with minimal system impact. All operations remain local, with no cloud components, trusts, or external dependencies, intended to support data privacy and compliance requirements.
