Industrial and building systems security
Assessments and architecture reviews for operational technology: plant floors, building controls, and the networks that were never meant to meet the internet.

Threat modeling and testing for LLM applications and autonomous agents. Prompt injection, tool abuse, and agents holding more keys than they need.
-
Risk reviews
Plain-language estimates of what can go wrong, how likely it is, and what it costs. The odds, written down before the bad night.

Software
Small apps and internal tools, built to ship and built to be maintained.
About
Midnight Actuary is an independent practice for security, risk, and software work. It prices the odds on systems where a failure has real consequences, then helps bring them down.
Failures keep their own hours. The work happens before they arrive.
