Bruno Abreu

I'm Bruno Abreu, an Information Systems and Economics graduate, transitioning to Cybersecurity. I'm currently studying information security fundamentals and preparing for the CompTIA Security+ certification.

I created DetonaDev Cyber Lab to document my practical studies in Linux, networks, firewall, logs, SOC, incident response, and tools used in security environments. The goal is to record the learning process transparently, technically, and objectively — showing not just commands, but also the reasoning behind each configuration, diagnosis, and solution.

My previous experience includes web projects, automation, published apps, and technology applied to business. This background complements my transition to cybersecurity with a practical understanding of how systems work, where they can fail, and how to protect information in real environments.
