[About me]

Dr. Bernhards Blumbergs is a lead cyber-security expert at the Information Technology Security Incident Response Institution of the Republic of Latvia (CERT.LV) and the former Technology Researcher at the NATO Cooperative Cyber Defence Centre of Excellence (NATO CCD COE) also the Ambassador of the Centre since 2018. Currently, he is doing his postdoctoral research project at the Nara Institute of Science of Technology, in Japan, within the JSPS fellowship.

His primary focus is on technical red teaming operation execution and leading threat hunting operations against national critical infrastructure. He is the creator and the technical director of the world’s largest and most innovative full-spectrum offensive cyber operation exercise Crossed Swords. He is a certified exploit researcher and advanced penetration tester (GXPN), industrial cyber security professional (GICSP), and response and industrial defense expert (GRID). He has a solid military background, targeted at developing, administering, and securing wide-area information systems.

Dr. Blumbergs received his Computer Science Ph.D. degree in Cyber Security from Tallinn Technical University in 2019, with his dissertation on specialized cyber red team responsive computer network operations.
