About
Safeguarding the digital evolution
TrueCustodian is a knowledge and media platform for cybersecurity practitioners — SOC analysts, penetration testers, forensic investigators, and the engineers building the defenses behind them.
Make hard-won operational knowledge — the kind usually locked in Slack threads and postmortems — available to anyone doing the work, in a form they can actually use on shift.
A security community where the gap between “wrote a detection” and “shipped a detection that holds up in production” keeps getting smaller.
Our story
Built by people who were tired of the same three blog templates
TrueCustodian started as a shared notes doc between analysts and testers who kept re-explaining the same triage steps and scoping checklists to new hires. Turning that into a public platform meant the next person starting out wouldn't have to learn it the slow way — one incident at a time.
What we value
The standard behind every published piece
Practitioner-first
Every piece is written by someone who has done the work, not summarized it secondhand.
Evidence over hype
We favor reproducible technique and cited detail over vendor talking points.
Clarity over jargon
Complex ideas explained precisely, without inflating them to sound impressive.
Community-driven
The best detections and playbooks come from practitioners comparing notes, not working alone.
