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 one advisory meeting a month π·
Advisory Services
My job is to translate between management and security.
Security Advisory Retainer
Monthly meetings to map out your security challenges, set priorities, and propose concrete actions. We also help prepare materials for board and management meetings.
Regulatory & Guideline Compliance
We assess your readiness against JFSA guidelines, FISC security standards, and industry frameworks β from gap analysis to policy development and audit support.
Security by Design Adoption
Shift from "protect after building" to "protect while building." We help you embed security throughout your development lifecycle.
AI Adoption & Zero Trust Advisory
From safe internal rules for generative AI to rethinking your IT environment with Zero Trust in mind β we help you prepare for what's next.

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.
