Same discipline. Different products. Ship what matters. Skip the noise.

Leadership Without Ego
It’s about what gets done.
Why “Sigil”
A sigil is a protective mark — a seal placed to ward against harm before it arrives. The name fits the product. Sigil scans AI agent code before it runs. The protection comes first. Not after the breach. Not after the incident report. Before anything executes.
A Protective Mark for Every Line of Code
AI agents write code, pull packages, run scripts, modify configs. Most of it executes before anyone reviews it.
Sigil quarantines and scans AI agent code before it runs. Eight scan phases. Deterministic analysis. Nothing runs until you say so.
Open Source
Sigil's CLI is open source under Apache 2.0. The scanning engine and local analysis pipeline are freely available.
