Checked 2026-09-04. Every line links the page we found it on. A cross means we found nothing at the addresses we checked, not that the vendor has no such document. A transparency score, not a product rating.
The evidence pack carries every criterion with its source, the addresses we checked, the date and the data snapshot id – the four things a procurement file needs and a screenshot loses. We do not issue badges: a badge is the first step towards a paid placement, and there is none here.
The label is the whole measurement in one object: every criterion with its weight, the band, and the date. Public transparency score, not a product or security rating.
Every line in it links the page we found the result on, or lists the addresses we checked. A cross means we found nothing there, not that mailcow has no such document.
