Roles

8 archetypes of the technology and security chair, each an educational lens, not a personality category. A real CIO or CISO is usually two or three at once; the point of the library is to see how the job’s demands — scale, regulator, mandate, reporting line — change the ideal profile.

Family

By scale

Enterprise CIOThe Architect — runs technology for an enterprise through governance, portfolio, platforms, capital and board reporting rather than through work they can see, and whose dominant danger is isolation dressed as a green dashboard.6 modules Mid-Market CIOThe Coach — the first real technology leader of a company that has outgrown one person, who must build a leadership team, a cadence and decision rights while making the ERP and cloud decisions that will outlast their tenure.6 modules SMB / MSP Technology LeaderThe one-person CIO and CISO of a small company or the MSP that serves fifty of them — hands on a vendor-managed stack, no peer to check the work, and a dominant danger of doing too little rather than too much.7 modules

By industry

Regulated-Industry CIO/CISOTechnology and security leadership where a regulator sits inside governance — financial services, healthcare, defense — and "enablement with institutional paranoia" is not a disposition but the written job description.7 modules

By mandate and situation

Post-Breach CISOHired in the weeks after the incident to centralize, replace, decide and move — with the turnaround paradox waiting at the end of it: the settings that save a security program in year one suffocate it by year three.7 modules Transformation CIOHired to change how the company works rather than to run what it has — unusually high discretion, unusually short tenure, and a signature danger of change without end, announced faster than the organization can absorb it.6 modules

By style

Business-Risk CISOThe security leader who speaks in prices rather than controls — board-fluent, enablement-first, trusted by the business, and dangerous when "yes" becomes an identity and nobody has verified the controls behind the price.7 modules Technical CISOEngineer-first and deep in the control plane — credible with the people who build the systems, and dangerous when rigor hardens into bureaucracy and "no" becomes an identity rather than a priced answer.7 modules

Style archetypes (Technical CISO, Business-Risk CISO) are cross-cutting and explicitly framed as dial settings rather than categories. Every page carries the same eighteen sections and a default Trait Dial profile to compare against your own.
