Florencio has had cybersecurity in his veins since he was a kid. He started in cybersecurity around 1998 (time flies!) first as a hobby and then professionally. His first job required him to develop a host-based intrusion detection system in Python and for Linux for a research group in his university. Between 2008 and 2015 he had his own startup, which offered cybersecurity consulting services. He was CISO and head of security of a big retail company in Spain (more than 100k RHEL devices, including POS systems). Since 2020, he has worked at Red Hat as a Product Security Engineer and Architect.
