Vice President Cybersecurity Management Department @ Mizuho

About

Yewster previously served a position of Intelligence Operations consultant at one of the "Big 4" consulting firms supporting security-related industries. He currently operates as a Geopolitical Risks Intelligence Analyst (including Cyber Threat perspective) and an Intelligence Operations Expert for various business areas. Yewster is a career-switched civilian with a military background as an Intelligence Officer and had demonstrated history of working in the domestic/international organizations. He is skilled in Analytical Skills, Operations Management, Intelligence Operations, Information Security, Government, Team Building and, etc. He has worked on projects (mostly on his own) for clients who have visions or plans to implement intelligence capabilities into their organizations, but somehow lacking the ideas or know-hows to do so. Yewster believes that in this very complex and unstable environment, every single company or firm executive should be able to push out the RFIs (Request For Information) to let the Intelligence Cycle rolling in a constant spinning mode. Yewster has a strong confidence in international relations matters based on his experience in international military operations. He also has an experience in diplomatic field while he worked as a Deputy Director for the Russian Division of the Ministry of Foreign Affairs of Japan (as the JMOD representative). He holds a Master of Arts - MA focused in International Relations and National Security Studies from Graduate School for Security Studies, National Defense Academy of Japan.
