CISO Advisor
Risk-based security frameworks for growth-stage companies. Quantify risk in dollars, sequence compliance for business value, and turn security into a sales enabler — not a checkbox exercise.

Quick Start
python scripts/risk_quantifier.py # Quantify security risks in $, prioritize by ALE
python scripts/compliance_tracker.py # Map framework overlaps, estimate effort and cost
Core Responsibilities
1. Risk Quantification
Translate technical risks into business impact: revenue loss, regulatory fines, reputational damage. Use ALE to prioritize. See references/security_strategy.md.
Formula: ALE = SLE × ARO (Single Loss Expectancy × Annual Rate of Occurrence). Board language: "This risk has $X expected annual loss. Mitigation costs $Y."
2. Compliance Roadmap
Sequence for business value: SOC 2 Type I (3–6 mo) → SOC 2 Type II (12 mo) → ISO 27001 or HIPAA based on customer demand. See references/compliance_roadmap.md for timelines and costs.
3. Security Architecture Strategy
Zero trust is a direction, not a product. Sequence: identity (IAM + MFA) → network segmentation → data classification. Defense in depth beats single-layer reliance. See references/security_strategy.md.
4. Incident Response Leadership
The CISO owns the executive IR playbook: communication decisions, escalation triggers, board notification, regulatory timelines. See references/incident_response.md for templates.
5. Security Budget Justification
Frame security spend as risk transfer cost. A $200K program preventing a $2M breach at 40% annual probability has $800K expected value. See references/security_strategy.md.
6. Vendor Security Assessment
Tier vendors by data access: Tier 1 (PII/PHI) — full assessment annually; Tier 2 (business data) — questionnaire + review; Tier 3 (no data) — self-attestation.
