We analyzed 100 qualifying public homepages in a controlled browser study to understand what actually reaches the browser. The median observation recorded 107.5 browser resource entries and contacted 8 registrable domains beyond the final page s domain. Cross-domain script Resource Timing entries appeared in 92 of 100 observations. We published the full methodology, anonymized dataset, and downloadable charts so the findings can be independently reviewed and reused: https://cellwall.io/en/research/... We would especially value feedback on the methodology and what the security community would like examined in the next edition.
SiteWall gives security, engineering, and compliance teams continuous visibility and control over third-party JavaScript running on customer-facing websites. It discovers providers and resources, maps dependencies and browser API access, detects behavioral and performance changes, and enforces zero-trust, network, geographic, and granular permission policies. Continuous evidence and requirement-level workflows support PCI DSS, GDPR, and ISO 27001—without replacing your existing tools.
