πŸ›‘οΈ For leaders of SMEs & startups

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.

Worries

A client or auditor asked us to explain our security posture β€” and we don't know what to say…

We can't afford a CISO or a dedicated security team, but we worry whether we're really okay…

The guidelines and regulations are too dense β€” we can't tell what actually applies to us…

Let’s untangle those worries together, starting with one advisory meeting a month 🌷

Profile

Natsumi Otani

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 JFSA 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.
