Alexis Fernández (a.k.a. six2dez) — CEO
Cybersecurity professional with over a decade of experience in offensive security, red teaming, and application security. My career has evolved from hands-on technical operations and tool development to leading and scaling security services across a large, multi-entity organization. I currently serve as Security Services Manager and Red Team at Visma. My focus is on building measurable and efficient services: defining operational models and KPIs, driving automation, supporting technical service owners and ensuring consistent maturity across all areas. Despite moving into a managerial role, I maintain a strong technical background, particularly in offensive security and control validation, and continue to contribute to the community as the creator of several open-source projects, including ReconFTW. I’m interested in scalable security architectures, operational efficiency, and fostering collaboration between offensive and defensive teams to continuously improve detection and resilience.
