Purpose and boundaries

This is an awareness and decision-support assessment. It is not an audit, certification, legal opinion, or formal compliance determination. The score is designed to help leadership identify where deeper review, evidence, or remediation is warranted.

Scoring model

  1. Each question is scored from 0–4. The highest score represents a formalized, implemented, tested, and evidenced state.
  2. Questions are assigned to governance domains. Each domain score is the ratio of earned points to available points in that domain.
  3. Domain scores are combined into the overall score using the domain weights shown below.
  4. “Not sure” answers are treated as an uncertainty signal and may apply a modest uncertainty adjustment.
  5. Some foundational questions have critical rules. If a critical foundation is absent, the overall score can be capped so a high average does not hide material risk.

Domain weights

Leadership ownership25%

Who owns risk, budget, and security decisions.

Business pressure20%

Customer, audit, insurance, or investor pressure.

Risk visibility15%

Visibility of assets, risks, vendors, and dependencies.

Customer trust evidence20%

Ability to prove controls to customers and partners.

Incident readiness20%

Preparation for incidents, disruption, and recovery.

Critical score rules

  • No clear security owner caps maturity because accountability is not yet established. (maximum score: 70)
  • No risk register or risk list limits decision quality. (maximum score: 70)
  • Weak evidence makes customer and audit readiness unreliable. (maximum score: 65)
  • Incident readiness cannot be strong without a clear response owner. (maximum score: 75)

How to use the result

Review the three lowest domains, critical flags, and evidence checklist together. The objective is not to generate a high score; it is to make missing decisions, owners, and evidence visible. When a major customer, audit, regulatory, or incident deadline exists, the self-assessment should be followed by independent validation.
