License Plans

Energy Logserver is available in the following plans:

  • Log Management Plan (LMP) — base platform for centralized log management and operational monitoring

  • SIEM Plan — add-on package extending LMP with SIEM capabilities (requires additional license)

  • Network Probe — add-on package for network traffic analysis, available in configurable node count (requires additional license)

  • AI Assistant — add-on enabling LLM-based features in Discover (requires additional license)

  • MSSP — mode for managed service providers enabling multi-tenant source management (requires additional license)
