About

The Pentester's OS.

ATHELOS is a single command center for running a security practice. Clients, engagements, findings, evidence, reports, invoices, playbooks, cheat-sheets, and local AI — all in one place.

Run it in the cloud, on your own infrastructure, or on dedicated servers we operate for you. Same platform, same workflow, same guarantees about your data.

Run it how you want.

Three delivery models. Same tool.

CloudWe host it

Sign up in a browser, start working in minutes. No install, no Docker, no infrastructure. ATHELOS runs on our infrastructure and you get straight to the work.

Best for: Solo operators, small teams, anyone who wants zero setup.

Self-hostedYou host it

Run the Docker image on your laptop, your VPS, or your server. Full control over the environment, the data, and the uptime. Your client data never leaves your infrastructure.

Best for: Privacy-focused operators, compliance-bound teams, air-gapped environments.

DedicatedWe run it for you

ATHELOS deployed on dedicated infrastructure for one customer — hosted by us, or shipped as an appliance to your data center. Contract, SLA, and support scoped to your organization.

Best for: Enterprise, government, defense, and regulated industries.

Why it exists.

A pentester's work is scattered. Notes in one app, findings in another, evidence in a shared drive, reports in Word, invoices in a spreadsheet. Every engagement starts by rebuilding context from six places.

ATHELOS collapses all of it into one pane of glass so nothing falls through the cracks — whether you're a solo operator on a laptop or a fifty-person security team running shared engagements across regions.

It's built to work for anyone who does the work: freelancers, boutiques, in-house teams, MSSPs, government, and defense. One product, three delivery models, no compromise on how your client data is handled.

Principles.

Three rules we don't break.

Private by design

Your client data stays yours. No telemetry. No analytics. No cloud AI. Whether you run in the cloud or self-host, ATHELOS is built so nothing about your work leaks.

Available your way

Cloud for zero setup. Self-hosted for full control. Dedicated for enterprise requirements. Three delivery models, one product. Pick what fits your team.

Built for operators

One pane of glass. Zero reliance on memory. Every feature assumes you're a skilled pentester who wants to move fast and not fight their software.
