Overview

0 days since the newest dated result, 0 since the oldest. 12 of 12 criteria have a measured result in the last 30 days. Failed checks and undated results are excluded.

Evidence freshness is a statement about our measurement and is kept apart from the transparency score, which is frozen at v1. How good our own measurement is.

Checked 2026-10-20. 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.

Downloads include all checks, source URLs, dates and the snapshot ID for your procurement file. We do not issue badges.

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 Retarus has no such document.
