The Person Behind the Brand
I'm Kyrian Onyeagusi, Director of Security at CyberKyrian and Assistant Manager of Security Engineering at Ethnos Cyber Ltd in Lagos. My work spans financial institutions, government agencies, and energy companies across Nigeria.
I built CyberKyrian to close the gap between enterprise-grade security thinking and the realities of Nigerian SMEs — businesses that face real threats but rarely have access to the tools, guidance, and awareness they need to stay safe.
Beyond consulting, I teach security architecture, mentor aspiring engineers, and publish research with CSEAN (Cybersecurity Experts Association of Nigeria). I've trained over 500 students and helped 50+ individuals transition into security careers.
