## Description

Use for security leadership decisions: a security program, budget justification in dollars, SOC 2 vs ISO 27001 vs HIPAA roadmap, or board security reporting. Quantifies risk with risk_quantifier.py and tracks compliance with compliance_tracker.py.

# 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`.
