CISSP AdvisorySecurity Advisory
We provide information security advisory and consulting services by an ISC2-certified CISSP professional. We do not accept fixed-price contract (請負) work. We are available under quasi-delegation contracts (準委任), advisory retainers, or spot consulting engagements.
CISSP requires a minimum of five years of verified, hands-on security experience. The exam — an adaptive test of up to 150 questions delivered in English — is designed to assess judgment and decision-making, not memorization. After certification, holders must complete 120+ CPE credits every three years and uphold the ISC2 Code of Ethics. This combination of experience requirements, continuous education, and ethical accountability is what makes a CISSP a credible and trustworthy basis for independent third-party verification.
I've written about what actually changed after earning CISSP — from both an engineer's and a business owner's perspective — on Qiita (Japanese).
Fractional CISO Services
A Fractional CISO gives your organization access to senior security leadership on a retainer or spot-consulting basis — without the overhead of a full-time hire. Ideal for SMEs, startups, and foreign-owned companies in Japan that need strategic security direction but don't require a dedicated full-time CISO.
- Security strategy and roadmap development
- Executive-level risk reporting and security policy definition
- Incident response decision support and stakeholder communication
- Vendor and third-party security risk assessment
Cybersecurity Rating (SCS ★3) Specialist Verification
We offer specialist verification consultations for companies pursuing ★3 under Japan's Supply Chain Security (SCS) Evaluation Framework, promoted by METI. The ★3 tier requires an independent CISSP-qualified professional to review and sign off on 83 self-assessment criteria. The framework is scheduled to launch by the end of fiscal year 2026 — now is the ideal time to start preparing.
- Gap analysis and advisory for SCS ★3 certification
- Review and guidance on 83-item self-assessment checklist
- Specialist sign-off (independent third-party verification by a CISSP holder)
- Continuous improvement support after certification
Field-Based Expertise That Big Firms Can't Match
Large consulting firms tend to rely on document-based assessments because they have never worked in actual development environments. We bring hands-on perspective from both well-run projects and projects with serious security gaps — which means we know what real risks look like on the ground.
- IoT & OT Security: Firmware development on ESP32 and PIC microcontrollers, PCB circuit design through Gerber data and board assembly. We understand hardware-layer risks that cloud-only consultants never see.
- Real-World Risk Patterns: Hardcoded SSH keys, credentials committed to repositories, and other field-common vulnerabilities are familiar territory. We provide substantive verification — not rubber-stamping — that prevents self-assessments from becoming mere formalities.
- Cloud to Edge: Combining AWS cloud architecture with embedded and hardware development, we can assess risk across the full supply chain — from the data center to the device.
