Turning complex security into plain business language.
Your company's friendly guardian advisor.
An advisor with dual expertise in cybersecurity and management consulting walks alongside you β from regulatory compliance and internal governance to incident preparedness β always from a business perspective. "We have no IT security staff" or "we don't know where to start"? You're exactly who we're here for.
Sound familiar?
A client or auditor asked us to explain our security posture β and we don't know what to sayβ¦
We can't afford a CISO or a dedicated security team, but we worry whether we're really okayβ¦
The guidelines and regulations are too dense β we can't tell what actually applies to usβ¦
Letβs untangle those worries together, starting with regular advisory meetings π·
What Is Happening Now
Growing cyber losses
Global losses from cybercrime are projected to reach the scale of US$23 trillion by 2027, and the IMF has repeatedly warned of cyber threats as a risk to financial stability.
AI-accelerated attacks
Recent reporting by Kroll highlights how AI is accelerating cybercrime targeting finance and space β outpacing the assumptions behind traditional defenses.
How we stay ahead
Our motto is to keep our AI security practice current β from prompt-injection countermeasures to published research such as Google, CrowdStrike, and Anthropic red-team reports and MITRE ATT&CK.
That is why space and DX projects need Security by Design β
and an expert who can translate it into the language of management.
Advisory Services
My job is to translate between management and security.

Regulatory & Guideline Compliance
We assess your readiness against Japan FSA guidelines, FISC security standards, and industry frameworks β from gap analysis to policy development and audit support.

Profile
Natsumi Otani (倧谷 θζηΎ)
Cybersecurity & Management Consultant
After graduating from university, I spent over 14 years at a major consulting firm working in cybersecurity and management consulting, primarily for financial institutions and the defense industry.
My work spans Japan FSA guideline compliance, security strategy through implementation, Zero Trust, AI-driven efficiency, frontier AI readiness, AI governance, and Security by Design β
supporting corporate security programs from both the management and the technology perspectives.
Encouraged by the positive feedback from many clients, I have now launched this advisory service.
Track record: megabanks, major life insurers, large financial companies (market cap over Β₯1 trillion), major defense contractors, and Japan's Ministry of Defense β including projects worth tens of billions of yen.
Making the complex simple β that's my motto.
