Eleftherios Antoniades

Eleftherios Antoniades is the Founder and Chief Technology Officer of Odyssey Cybersecurity and the creator of the award-winning ClearSkies™ platform. A visionary thought leader, Eleftherios has dedicated his career to advancing cybersecurity internationally.
He studied Computer Science & Electrical Engineering at the New York Institute of Technology and earned a Master’s degree in Information Technology from George Mason University. His career in cybersecurity began in the United States. During his research work, he collaborated on a U.S. government-funded project focused on securing the then-nascent TCP/IP, CGI, and HTTP protocols—technologies that would later form the backbone of the Internet.
In 2002, he founded Odyssey with the vision of helping organizations navigate digital risk through innovation and resilience. Despite the challenges of building a global player from Cyprus, he led the creation of ClearSkies™, which earned international recognition, including a position in Gartner’s Magic Quadrant for SIEM twice - one of the very few European brands to be included on the global cybersecurity map.
Today, Eleftherios is a strong advocate for cyber-resilience in the AI era. Under his leadership, ClearSkies™ was built as an AI-native Threat Detection, Investigation & Response platform that helps Security Operations teams see in real time, understand in context, and respond at machine speed - empowering them to detect faster, adapt smarter and ensure operational continuity.
