Reading this observatory

Every figure on this site is read from the observatory’s PostgreSQL store at request time. Where a measurement does not exist, the interface says so rather than showing a zero as a result.

Interpretation

Geolocation is an estimate and carries its source and confidence.
Technology detections carry confidence and evidence; weak evidence is not stated as fact.
Vulnerability matches are potential exposures based on versions — unverified.
Only assets inside the authorised observation boundary are ever probed.
