Graduated in computer engineering, Javier Espejo soon became interested in security in cyberspace and is now a reference in the field. He has a precise and analytical vision of the technological world that he applies in all its extension in Transparent Edge Services, which he cofounded. Javi has worked for large companies and public administrations, finding their vulnerabilities and proposing solutions. He devotes considerable effort to raising awareness of security and protection of individuals and companies against increasingly professional cyber-crime and gives classes in masters programs and seminars at leading institutions. His love of bad jokes contrasts with his seriousness at work. In his free time, he dedicates himself to the defense of animal rights as a volunteer in a rescue organization. And he always finds time for his dog Charli, whom he rescued years ago.
