I got tired of security tools that wake me up at 3am with alerts but leave all the real work to me.

So I built **Cortex** — the autonomous decision engine that powers [Watch](https://watch.alsopss.com).

Most tools (Falco, Wazuh, OSSEC, etc.) are great at **detecting** things, but terrible at **deciding** what to do about them. You end up with alert fatigue and manual investigation every single time.

I wanted something different.

Cortex is the AI-powered security brain inside Watch. It runs on every server and works like this:

**Context** — Automatically builds a rich snapshot of the system (processes with ancestry, network connections, file integrity, SSH activity, DNS queries, etc.)

**Reason** — The on-device AI analyzes everything and answers:

**Plan** — If action is needed, it creates a clear, safe response plan (ban IP, kill process, revert file changes, etc.). It also **deduplicates** plans so you don’t get spammed with the same alert 50 times.

**Actuate** — It can act autonomously (in Autopilot or Sovereign mode) or queue the plan for your one-click approval.

All of this happens **on-device**, in milliseconds, even if the backend is unreachable.

When a brute-force attack hits, you can literally watch Cortex:

You see the full reasoning chain in plain English.

I run a small independent software company (AL'S-OPS LLC) and got frustrated with the existing tools. Either they were:

Cortex was designed to fix all four problems.
