Marco Ortisi works as Senior Penetration Tester in ENCS (European Network for Cyber Security) where he is fully involved in increasing the security of European critical infrastractures such as energy grids, and reducing the gap with the classical IT systems. Netizen since 1996, he has literally grown up on "bread and vulnerability's research," a fascinating field leading him to continuosly study new attack techniques and at the same time to develop alternative defense methods. Prior to this role at ENCS, Marco worked as Independent Penetration Tester and Security Consultant on different sectors (telco, governmental, utility, banking, pharmaceutical, financial, etc...) by helping to improve the IT security posture of several big companies and organizations operating in EMEA (Europe and Middle East).
