Risk quantification in dollars, compliance roadmap (SOC 2/ISO 27001/HIPAA/GDPR), security architecture strategy, incident response leadership, and board-level security reporting. Use when building security programs, justifying security budget, selecting compliance frameworks, managing incidents, assessing vendor risk, or when user mentions CISO, security strategy, compliance roadmap, zero trust, or board security reporting."

---# 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.
## Keywords
CISO, security strategy, risk quantification, ALE, SLE, ARO, security posture, compliance roadmap, SOC 2, ISO 27001, HIPAA, GDPR, zero trust, defense in depth, incident response, board security reporting, vendor assessment, security budget, cyber risk, program maturity
## Quick Start
```bash
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.
## Key Questions a CISO Asks
- "What's our crown jewel data, and who can access it right now?"
- "If we had a breach today, what's our regulatory notification timeline?"
- "Which compliance framework do our top 3 prospects actually require?"
- "What's our blast radius if our largest SaaS vendor is compromised?"
- "We spent $X on security last year — what specific risks did that reduce?"
## Security Metrics
| Category | Metric | Target |
|----------|--------|--------|
| Risk | ALE coverage (mitigated risk / total risk) | > 80% |
| Detection | Mean Time to Detect (MTTD) | < 24 hours |
| Response | Mean Time to Respond (MTTR) | < 4 hours |
Evaluate every decision through probability × impact. Quantify risks in business terms (dollars, not severity labels). Prioritize by expected annual loss.
