Athena Documentation
Athena Deploy Center is SealGrid's self-hosted, air-gap-first platform for software deployment and inventory across Windows and Linux endpoints — a modern, fully on-premises replacement for SCCM and PDQ. These docs cover installing the server, enrolling agents, and operating your fleet without any cloud dependency.
Follow the Beginner Guide: download the appliance, answer its setup questions, sign in, and enroll your first agent. Everything runs inside your perimeter — no internet access is required at any step.
What is Athena#
Athena is built from three parts that you host yourself:
- Athena Server — a single ASP.NET Core application that hosts both the
Blazor web console and the API/agent gateway. Web UI on port
8443, the agent gateway on port8444. - Hermes Agent — a lightweight Windows/Linux agent that executes deployments, runs remote commands, and collects inventory. It connects outbound only to the server.
- Plugins — pluggable database (SQLite, PostgreSQL) and audit providers (File, Syslog) loaded at startup.
Quick start#
The fastest path from zero to a managed endpoint (step by step in the Beginner Guide):
- Import the virtual appliance and answer its five setup questions.
- Sign in at
https://<host>:8443asadminwith the password shown on the appliance console. - Install your first agent: Agents → Install agent, then run the one-liner on a target.
- Build a deployment package and roll it out to the agent.
