00 / Profile
Offensive thinking.
Defensive discipline.
BLTSEC is the security engineering work of Brennan Lee Turner—focused on making complex operator tasks safer, faster, and easier to reproduce. The work lives where practical automation, adversary simulation, and accountable infrastructure meet.
01 / Selected work
Tools for the field.
Small surfaces. Clear contracts. Useful under pressure.
Active
NOCAP
A zero-dependency command capture wrapper for security operators—live output, smart routing, clean evidence.
Public
DECON
Sanitize operational data while preserving the structure analysts need.
Public
PivotLab
A repeatable Ludus range for learning and practicing network pivot techniques.
Public
Violent Python 3
Modernized security and forensics exercises inspired by a classic field guide.
02 / Principles
Professional is a behavior.
-
01
Authorization before action.
Clear scope, explicit boundaries, and no ambiguity about the work.
-
02
Evidence before confidence.
Test the claim, capture the result, and make failure visible.
-
03
Stand down clean.
Teardown, absence proof, and responsible handling are part of delivery.
03 / Connect
Open source, practical research, and tools built for real workflows.
