70/100BBand B

Rank 1 of 29 in Feature flags and experimentation, where the median is 30.

We measured 12 of 12 criteria for VWO on 2026-09-13. We found 8 with a source and did not find 4 at the addresses we checked. That is a transparency score of 70 out of 100, band B.

Overview

0 days since the newest finding, 0 since the oldest. 12 of 12 criteria measured in the last 30 days.

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.

Measured behaviour2 of 3 found

Checked 2026-09-13. 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 VWO has no such document.

29 vendors with a score; 1 more without a score because we could measure too little. Bands have fixed thresholds, see how the score works.

The band of VWO is marked. Vendors without a score are the ones where we could measure too few criteria to rank them – a gap on our side, counted separately.
