- Web agencies managing client domains
- Worth noticing
- The scanner checks CAA records and uses RDAP for registration details; host and CDN identification is explicitly described as a best guess.
Field notes
The scanner accepts domains on separate lines or separated by commas or spaces, and the results can be downloaded as a CSV. Its checks extend to CAA records that could prevent the current certificate authority from issuing a renewal; host and CDN identification is labeled a best guess. The page reports findings from a review of 329 sites across 20 agency portfolios, while noting that some country domains do not publish registration data.
