The request "ctr" is ambiguous; it most plausibly refers to certificate transparency (CT) lookups or to a CTR-related tool, and no product page clearly matches it as a named product. The sources that bear on certificate transparency are Cloudflare, which indexes CT radar actions 6, and CTlogs.io, a dedicated CT log search service 10. Which platform or constraint you have in mind would help narrow this.
A question back: Do you mean certificate transparency (CT) lookups, or something else by "ctr" (for example a click-through rate tool or a specific product name)?
