Assess security program maturity against NIST CSF 2.0 (organizational profiles and tiers), CIS Controls v8.1 implementation groups, or C2M2 — evidence-based current vs. target profiles, gap prioritization and a funded roadmap. Use for annual program assessments, board reporting, after a new CISO starts, or to prioritize security investment.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

Security Maturity Assessment
Choose the frame
| Framework | Use when |
| NIST CSF 2.0 (Govern, Identify, Protect, Detect, Respond, Recover; tiers 1–4; Current/Target Profiles) | Enterprise-wide outcome view, board reporting |
| CIS Controls v8.1 (18 controls, IG1/IG2/IG3 safeguards) | Prescriptive technical baseline, smaller orgs |
| C2M2 | Energy/OT and critical infrastructure |
| ISO/IEC 27001 | Certification-oriented ISMS |
Method
- Scope business units and environments.
- Collect evidence per subcategory/safeguard: documents, configuration exports, metrics (coverage %, SLAs), interviews, sampling. Score on evidence, not self-reporting.
- Score: e.g., 0 not implemented / 1 partial / 2 implemented in parts / 3 implemented and measured / 4 optimized; or CSF tiers for governance aspects.
- Set target profile from risk appetite, threat profile, regulatory needs — not everything must be "4".
- Prioritize gaps by risk reduction per cost; tie to top risks (
risk-register). - Roadmap: 3–4 quarters of initiatives with owners, budget, success metrics.
Evidence examples
- PR.AA (Identity Management, Authentication, Access Control): % accounts with phishing-resistant MFA, access review completion.
- DE.CM (Continuous Monitoring): EDR coverage, log source coverage vs. inventory.
- RS.MA (Incident Management): tabletop dates, IR plan currency, MTTD/MTTR.
- RC.RP (Incident Recovery Plan Execution): restore test results, RTO met?
- GV.SC (Cybersecurity Supply Chain Risk Management): vendor tiering and assessment coverage.
Output
Function/Category | Subcategory | Current score | Evidence | Target | Gap | Initiative | Priority
- one-page summary: strengths, top 5 gaps, roadmap.

Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
