Methodology

This statistics compilation follows a rigorous methodology:

Source selection: Statistics are drawn from primary research sources (peer-reviewed academic papers, vendor security reports, regulatory documents) and secondary research sources (industry surveys, analyst reports). We prioritize sources that disclose their methodology and sample sizes.

Recency: All statistics are from 2024 or later. Where multiple data points exist for the same metric, we use the most recent.

Attribution: Every statistic includes its source and publication year. Where a statistic is derived from multiple sources, all sources are cited.

Updates: This page is reviewed and updated quarterly. Statistics that become outdated are replaced with current equivalents.

Limitations: Industry statistics, particularly from vendor reports, may reflect selection bias toward organisations engaged with the reporting vendor. Academic statistics may not reflect production deployment conditions. We note these limitations where relevant.
