Council · GSPC · 13 ETSI principles · 4 axes

Score your AI system's
governance — honest math.

13 principles from ETSI EN 304 223, mapped to 4 axes (G, S, P, C). Composite = geometric mean — a zero on any axis drops your score to zero. Free, runs entirely in your browser, no server.

What this scores

The 4 GSPC axes

G
—
Governance
S

Security
P

Privacy
C

Commerce

Each axis scores the fraction of applicable principles it passes. Principles don't contribute to axes that don't list them. A principle passes only when ALL its required keys are truthy.

Sources & honest scope

What this is

  • A browser-side port of sovos_core.gspc.score_gspc() — the same scoring logic the sov CLI runs.
  • The 13 principles come from ETSI EN 304 223 (AI cybersecurity, published Jan 2026).
  • The 4 axes (G/S/P/C) are CSOAI's GSPC framework.
  • Composite score = geometric mean of the 4 axes (so any zero = zero).

What this is NOT

  • Not a certification. It's an instrument, not a stamp. We surface UNMEASURED, not a "pass/fail" judgement.
  • Not exhaustive. Real ETSI EN 304 223 compliance requires documentation review, audit trail inspection, and human-in-the-loop oversight. This tool checks 36 control flags against 13 principles — that's the surface, not the substance.
  • Not a substitute for the GSPC sovereign stack (csoai-governance-crosswalk-mcp, mcp-sov-signal, csoai-c2pa-signer). These verify the same principles against real audit evidence at scale.

For enterprise use

  • pip install csoai-governance-crosswalk-mcp — MCP server with 10+ frameworks (EU AI Act, NIST RMF, ISO 42001, DORA, GDPR, NIS2)
  • Use the JSON export below as a record for the csoai-governance-crosswalk-mcp.query_crosswalk() API.
