New tool: Anonymous CSF Benchmarking (/grc/benchmark/). Compare your CSF 2.0 maturity to anonymous aggregates by sector (NACE top-level), size band and region. Opt-in only — the literal JSON payload is shown to you before sending; nothing else leaves. Aggregates only render when n ≥ 20 (k-anonymity), falling back to parent slices otherwise. No IP, user-agent or sub-month timestamps stored.
