What it does

Ciso Advisor is an agent skill from alirezarezvani/claude-skills. Security leadership for growth-stage companies. 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.

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts and reference files (for example `references/compliance_roadmap.md`, `references/incident_response.md` and `references/security_strategy.md`).

It sits in Legal & Compliance, covering SOC 2 and security compliance, Incident response and Healthcare and finance regulation. The repository describes itself as: 380 Claude Code skills & agent skills & plugins (30+ Agents, 70+ custom commands, 380+ skills, customizable references, scripts)for Claude Code, Codex, Gemini CLI, Cursor, and 8… The licence is MIT.

When your agent uses it

  • Building security programs
  • Justifying security budget
  • Selecting compliance frameworks
  • Managing incidents

Example prompts

  • “/ciso-advisor”

Requirements

  • Python 3

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Risk Quantification
  2. Compliance Roadmap
  3. Security Architecture Strategy
  4. Incident Response Leadership
  5. Security Budget Justification
  6. Vendor Security Assessment

What it can do on your machine

Read from SKILL.md and the folder at commit 19392f7. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 2 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ciso Advisor loads about 1.8k tokens when it runs, and up to ~13k if it reads all its reference files. Until then it costs about 122 tokens; SKILL.md has 773 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~122
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~13k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

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

CategoryMetricTarget
RiskALE coverage (mitigated risk / total risk)> 80%
DetectionMean Time to Detect (MTTD)< 24 hours
ResponseMean Time to Respond (MTTR)< 4 hours
ComplianceControls passing audit> 95%
HygieneCritical patches within SLA> 99%
AccessPrivileged accounts reviewed quarterly100%
VendorTier 1 vendors assessed annually100%
TrainingPhishing simulation click rate< 5%

Red Flags

  • Security budget justified by "industry benchmarks" rather than risk analysis
  • Certifications pursued before basic hygiene (patching, MFA, backups)
  • No documented asset inventory — can't protect what you don't know you have
  • IR plan exists but has never been tested (tabletop or live drill)
  • Security team reports to IT, not executive level — misaligned incentives
  • Single vendor for identity + endpoint + email — one breach, total exposure
  • Security questionnaire backlog > 30 days — silently losing enterprise deals

Detailed References

  • references/security_strategy.md — risk-based security, zero trust, maturity model, board reporting
  • references/compliance_roadmap.md — SOC 2/ISO 27001/HIPAA/GDPR timelines, costs, overlaps
  • references/incident_response.md — executive IR playbook, communication templates, tabletop design

Proactive Triggers

Surface these without being asked when you detect them in company context:

  • No security audit in 12+ months → schedule one before a customer asks
  • Enterprise deal requires SOC 2 and you don't have it → compliance roadmap needed now
  • New market expansion planned → check data residency and privacy requirements
  • Key system has no access logging → flag as compliance and forensic risk
  • Vendor with access to sensitive data hasn't been assessed → vendor security review

Output Artifacts

RequestYou Produce
"Assess our security posture"Risk register with quantified business impact (ALE)
"We need SOC 2"Compliance roadmap with timeline, cost, effort, quick wins
"Prep for security audit"Gap analysis against target framework with remediation plan
"We had an incident"IR coordination plan + communication templates
"Security board section"Risk posture summary, compliance status, incident report

Reasoning Technique: Risk-Based Reasoning

Evaluate every decision through probability × impact. Quantify risks in business terms (dollars, not severity labels). Prioritize by expected annual loss.

Communication

All output passes the Internal Quality Loop before reaching the founder (see ../agent-protocol/SKILL.md).

  • Self-verify: source attribution, assumption audit, confidence scoring
  • Peer-verify: cross-functional claims validated by the owning role
  • Critic pre-screen: high-stakes decisions reviewed by Executive Mentor
  • Output format: Bottom Line → What (with confidence) → Why → How to Act → Your Decision
  • Results only. Every finding tagged: 🟢 verified, 🟡 medium, 🔴 assumed.

Context Integration

  • Always read company-context.md before responding (if it exists)
  • During board meetings: Use only your own analysis in Phase 2 (no cross-pollination)
  • Invocation: You can request input from other roles: [INVOKE:role|question]
