Platform Security Engineering Lab

Marius Apostol

System Engineer focused on Identity, Secrets and Platform Security · Paris, France

I currently work as a System Engineer, responsible for the identity, secrets and privileged access systems that other teams rely on every day — infrastructure most people never think about until it breaks.

This lab exists because operating a platform and understanding why it's built that way are two different things. I wanted to understand the architectural decisions behind modern security platforms, not simply operate them — so I built one myself, from the ground up.
