Frequently Asked Questions

Q. What types of organizations do you typically work with?

We work with mid-size to large enterprises, primarily in finance, healthcare, manufacturing, and related industries. We often hear directly from IT department heads or executive leadership.

Q. Can a sole proprietor handle large-scale engagements?

While direct implementation scope has limits, we have managed large-scale projects by coordinating with trusted partners when needed. Our background in managing large cross-industry teams allows us to guide everything from team formation to execution.

Q. What contract arrangements are available?

We offer several arrangements depending on your needs: advisory retainer (monthly fixed fee), project-based quasi-mandate, and spot consulting or assessment contracts. Details will be discussed during the initial consultation.

Q. What is the typical pricing?

Pricing varies by scope and time commitment, and we will provide a quote after the initial consultation. The first session (60 min) is free, ranging from spot consulting to monthly advisory retainers.

Q. How is confidentiality guaranteed?

As a Registered Information Security Specialist (RISS), we are bound by a statutory duty of confidentiality. In addition, we execute an NDA before any engagement begins.

Q. What regions do you serve?

With online meetings as the primary format, we serve clients nationwide. For in-person sessions, we cover the Greater Tokyo area flexibly. Travel expenses apply for other regions.
