A security researcher conducted a follow-up analysis examining how organizations have adopted and configured framing protection security headers (X-Frame-Options and CSP frame-ancestors directives) across the internet’s most popular domains since 2023.

Understanding header adoption trends helps security teams benchmark their own implementations against industry practices.
