Bruno Cortes — CEO

Security leader with 14+ years of experience in Cyber Security and a broader career that includes previous roles as an Army officer and IT professional. Over this journey, I’ve worked in highly demanding technology and military environments — including the Brazilian Army, GoHacking and Nubank. I currently serve as Head of Global Security Operations at Nubank, leading a converged organization that brings together Cyber Security Operations (SOC, threat detection, incident response and Cyber Intelligence) and Corporate Security (physical security and protection of people, assets and facilities) across multiple regions. Throughout my career, I’ve been involved in different domains of Cyber Security, from hands-on technical work to strategic leadership, which today enables me to navigate and support diverse areas across the security landscape. I have led complex operations, designed and executed large‑scale exercises and transformation initiatives, and helped organizations strengthen their security posture and resilience end‑to‑end. I’m also a co‑founder and instructor at GoHacking, where I conduct trainings, workshops and talks in Cyber Security, creating practical experiences and simulations that bridge the gap between theory and real‑world scenarios. Core strengths: • Building and leading multidisciplinary security teams (cyber, physical and hybrid) • Global Security Operations: cyber + corporate security (people, assets and facilities) • Design and execution of cyber exercises, simulations and readiness programs • Translating complex security and risk scenarios into clear decisions for business and leadership • Developing talent and fostering a strong security culture across organizations Certifications: OSCP, OSWE, OSCE, OSWP, GPEN, GCIH.
