Kompli is a Linux security compliance engine for evaluating and remediating system configuration against industry benchmarks (CIS, STIG, etc.). It is derived from the Azure OSConfig project, retaining only the ComplianceEngine module and its direct dependencies.
This codebase originates from Azure OSConfig — a modular security configuration stack for Linux Edge devices developed by Microsoft, supporting multi-authority device management over Azure IoT Hub, GitOps, and local management. OSConfig consisted of a platform daemon, a PnP/MC adapter layer, and a set of management modules (CommandRunner, SecurityBaseline, DeviceInfo, Networking, Firewall, and others).
Kompli strips OSConfig down to a single module: ComplianceEngine (src/modules/complianceengine/). The MC (Machine Configuration) adapter, mpiclient, logging, telemetry, parson, and commonutils libraries are retained as they form the direct dependency chain of ComplianceEngine. Everything else — the platform daemon, PnP adapter, ASB/SSH adapters, and all non-CE modules — has been removed.

cmake --build build --target OsConfigResourceComplianceEngineThe build produces build/adapters/mc/complianceengine/libOsConfigResourceComplianceEngine.so.
cd build && ctestComplianceEngine is configured via /etc/osconfig/osconfig.json:
{
"LoggingLevel": 6
}LoggingLevel values: 6 = informational (default), 7 = debug.
To override automatic OS detection (useful for testing), create /etc/osconfig/system_id.override:
