## The panel's verdict

The captured pages gave this bench almost nothing to score. The listing puts Quantcast Choice in the consent management category, yet the captured homepage markets an AI-powered demand-side platform for performance marketers — proprietary AI called the Audience Graph and a campaign product named Q+ — and the only other page captured is a trademark notice; no page describes the banner a visitor would see. Banner and choice, prior blocking, scanning and classification, consent records, standards and platforms, and pricing transparency each score 0 across the computed table (minimum 0, maximum 0), with rationales citing no public information on each; 'Permisio', the one consent-adjacent mark, appears solely as a registered trademark with no description. Sovereignty is the sole criterion scored above zero — 1 from five of six judges, 0 for the remaining score — resting on a trademark notice naming Quantcast Corporation with marks registered in the United States: not an imprint, stating no place of incorporation, leaving hosting, data residency, subprocessors and a data processing agreement unstated. flagged splits came back empty — a shared absence of evidence, not a split between judges.

**Speaks for it:**
- Sovereignty drew the only nonzero scores on the table — 1 from five of six judges.
- The trademark notice is dated — updated August 12 2024 — and names Quantcast Corporation as holder of the listed marks.
- flagged splits came back empty, so the bench's findings are stable rather than contested.

**Held against it:**
- The captured pages document an advertising platform and a trademark notice, with no description of a consent banner, blocking, scanning, consent records or framework signals.
- Banner and choice, prior blocking, scanning and classification, consent records, standards and platforms and pricing transparency each score 0 across the computed table (minimum 0, maximum 0).
- 'Permisio', the only consent-adjacent mark listed, appears solely as a registered trademark with no description attached.
- The trademark notice is not an imprint: it states no place of incorporation, and hosting, data residency, subprocessors and a data processing agreement are unstated on the captured pages.
- No tiers, per-domain rates, free-tier limits or terms appear, so an annual cost cannot be computed from public material.

**Best for:**
- You already buy Quantcast's advertising platform and want consent management from the same vendor, with documentation supplied directly rather than from the public site.
- You evaluate CMPs through hands-on trials or vendor-supplied documentation before shortlisting, since the public pages support none of the checks this bench ran.

**Avoid if:**
- You need to verify banner choice design, prior blocking, scanning, consent records or IAB TCF / Google Consent Mode signals from public pages before contacting the vendor — the bench scored all of these 0.
- Your compliance process requires a reviewable data chain — ask the vendor: the public pages we read do not show it
- You came to the public site to research the consent product itself: the captured homepage markets an AI-powered demand-side platform for performance marketers.
- You must compute an annual cost from public prices before shortlisting.

## Scores by judge and criterion

Scores out of 5, each judge scoring independently against the published rubric (v1). "n/r" = not rated: the vendor publishes no price, or the judge found no public information on that criterion.

### The judges

- **The Data Protection Officer** (v1.0): External DPO for a dozen mid-sized companies, two of which received a letter from a state supervisory authority about their cookie banner last year. Wants reject on the first layer, nothing loaded before the click, a consent log that shows which banner version each visitor saw, a cookie list that matches the site, and a DPA and subprocessor list that keep visitor data in the EU.
- **The Agency Developer** (v1.0): Lead developer at a web agency that maintains forty client sites on WordPress, TYPO3 and Shopify. Wants one account for every client, blocking that works without rewriting each theme, content blockers for YouTube and Maps, a Tag Manager template, a scanner that flags the tracker a client added on Friday, and a JavaScript API documented well enough that forms and plugins can ask for consent.
- **The Publisher Marketing Lead** (v1.0): Runs marketing for an ad-funded news site and an online shop in the same group, where every point of consent rate shows up in ad revenue and in Google Ads conversions. Wants a registered IAB TCF CMP, Google Consent Mode v2 in advanced mode, banner tests within what the law allows, consent shared between the site and the app, and a dashboard that shows where visitors drop off.
- **The In-House Lawyer** (v1.0): In-house counsel at a retailer with shops in Germany, France and Austria, who has read the court decisions on missing reject buttons and the regulators' banner guidance. Wants § 25 TDDDG and the GDPR mapped to concrete settings, equal-weight choices as the default, consent that can be withdrawn as easily as it was given, and records that would hold up if a competitor or a consumer group sued.
- **The WordPress Webmaster** (v1.0): Looks after the WordPress site of a mid-sized engineering company on top of the actual job, with Google Analytics, a YouTube channel, a Maps embed and a contact form with reCAPTCHA. Wants a plugin that finds these by itself, blocks them until the visitor agrees, survives the next plugin update and caching, and costs a known amount per site per year without a call to sales.
- **The Skeptic** (v1.0): Has opened the browser's network tab on sites with a "certified" banner and watched the ad pixels fire before anything was clicked. Reads "consent rate optimisation" as a hint that reject will be grey and small, "auto-blocking" as a claim until the test steps are published, and "EU hosting" next to a US script CDN — and asks what leaving would cost: the consent logs, and every visitor asked again.
