Hi folks, my name is Marco also known as brmk.
I’ve been passionate about offensive security for years, dedicating a lot of time and energy to stay ahead in this ever-evolving field. My main focus is adversary emulation and red teaming, areas that are always pushing the limits and challenging me to grow. Every day, I’m all about learning, testing, and refining my skills.
To keep advancing, I use my personal homelab as my playground for security research. It’s where I keep my skills sharp and experiment with new tools and techniques, showcasing my genuine enthusiasm for this field.
The aim of this blog/site it's simple, to share what I’m learning, discovering, and finding useful. Obviously not in my native language, because I really like to smash my head on something while i'm trying to be better in english.
I don’t see myself as an expert who has “made it”, but rather as someone on a journey: always improving, always curious.
As a bit of background, I can share some of the certifications and training sessions I've attended over the years. This isn't a comprehensive list, and I understand that certificates do not prove anything, but... it's a bit of nerdy vanity.
