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.

New here?

Start with Installation to stand up the server, then 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 port 8444.
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:

Install the server by running the Docker container.
Sign in to the console at https://<host>:8443 with the default admin account.
Generate a registration token and run the one-line agent installer on a target.
Build a deployment package and roll it out to the agent.
