# What is Luumen?

> Luumen is an AI-powered SSH client for engineers who manage Linux and Windows infrastructure. LuumenAI is embedded in every session with full context on your hosts, OS, packages, and environments.

Luumen is an AI-powered SSH client built for engineers who manage Linux and Windows infrastructure. It connects to your servers over SSH or WinRM like other SSH clients (like Termius, PuTTY, or OpenSSH). The difference is **LuumenAI**, embedded in every session with full context on your hosts, OS, installed packages, and environments, ready to answer questions, suggest commands, and run them with your explicit approval.

## Who Luumen is for

Luumen is built for the people who keep infrastructure running:

* **SREs** who need to reduce MTTR and resolve incidents under pressure
* **Sysadmins** responsible for uptime, patching, security, and compliance
* **Network engineers** managing routers, switches, and firewalls across large device fleets
* **DevOps and platform engineers** automating routine operational work
* **Managed service providers** managing infrastructure across multiple client environments

## What makes Luumen different

* **Context-aware AI.** LuumenAI has full context on the host you're connected to: OS, packages, running services, and environment. Answers come from your live state, not generic advice.
* **LuumenAI Skills.** Turn your runbooks, SOPs, and tribal knowledge into reusable, shareable automated AI procedures. Skills run step-by-step with explicit human-in-the-loop approval at every action.
* **AI-assisted incident triage.** When something breaks, Luumen surfaces how similar incidents have been resolved before, drawing on session context, tickets, telemetry, and SOPs.
* **Vulnerability scanning.** Daily scans against the National Vulnerability Database and Open Source Vulnerabilities databases are included on every plan. Enterprise includes compliance and configuration scans.
* **Team collaboration.** Workspaces, role-based access, shared credentials, and shared AI Skills, so operational knowledge scales across your team.
