Panel verdict
The AI panel rates Didomi 3.5/5, the mean of 6 judges. Didomi's consent management platform earns its best marks on scanning and classification and consent records: a scanner covering up to 20,000 pages, working behind logins and from a chosen country, and a versions-and-proofs module from which legal teams can pull the exact UI a user agreed to on any date. how scores are made

Weighted verdict

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.

Same scores as the panel view — this lens weights them the way this judge cares.

Banner & choice architecture

How this is scored

What the visitor is asked and how: a reject option on the first layer with the same prominence as accept, consent by category and by vendor, withdrawal and changed choices as easy as the first consent (a persistent button or link), banner texts and layouts the site owner controls, languages, rules per country or regulation (GDPR, Swiss FADP, US state laws), accessibility of the banner itself, and consent-rate analytics or A/B tests that stay within the rules.

0 — Not a consent banner; the product shows a notice that cannot record a choice, or is a different kind of product.

3 — A banner with accept and a settings layer; whether reject sits on the first layer, how consent is withdrawn and how far the design can be changed are basic or not described.

5 — Accept, reject and settings on the first layer, consent by category, a way for visitors to change or withdraw their choice later, customisable texts, colours and layout, the banner in several languages, and a basic consent-rate statistic.

8 — Choice architecture documented in depth: reject and accept of equal weight stated as a default, consent per vendor or service as well as per category, geolocation rules that show a different banner per country or regulation, the banner stated as accessible (WCAG level named), dozens of languages with automatic detection, and consent-rate analytics or A/B testing with the limits on what may be tested explained.

10 — The choice is designed to stand up to a supervisory authority: templates mapped to named regulator guidance (for example the German DSK, CNIL or EDPB cookie banner report), dark patterns the product prevents listed, every banner version kept with its texts so the choice shown can be reconstructed, and consent-rate figures reported without nudging defaults.

Report an error

The Data Protection Officer

The captured help-centre pages describe a first layer where disagree is as easy as agree — one-click "Disagree and close" beside "Agree and close", with "Agree to all" and "Disagree to all" buttons enabled by default and unable to be disabled — and withdrawal required to be as easy as the first choice. Consent per vendor, geo-targeted banners per country, 45+ languages with automatic detection, A/B testing and consent analytics are all documented; we found no public information on a stated accessibility level for the banner itself or templates mapped to named regulator guidance, which keeps me short of the top. 9 10 2 3

Prior blocking & script control

How this is scored

What happens before the visitor decides: automatic blocking of scripts, pixels, cookies and embedded content until consent is given, content blockers with placeholders for videos, maps and social embeds, integration with tag managers (Google Tag Manager, Matomo Tag Manager) and server-side tagging, consent passed to forms and plugins, and a documented way for the site owner to check that nothing loads too early.

0 — No blocking of any kind; the product only shows a banner and leaves every script running.

3 — Blocking by hand: the site owner changes script tags or tag-manager triggers using the consent state; automatic blocking, embeds and testing are basic or not described.

5 — Automatic blocking of known scripts and cookies before consent, placeholders for embedded videos and maps, a Google Tag Manager template or integration, and the blocking method documented in the help centre.

8 — Blocking described in depth: an auto-blocking mode and a manual mode with their limits explained, content blockers for named services that the vendor maintains, consent passed to forms, CAPTCHAs and plugins through a JavaScript API or events, server-side tagging supported, and instructions to test in the browser or a tag-manager preview that nothing loads before consent.

10 — Prior blocking the site owner can verify: an automated check or monitor that reports scripts and cookies set before consent on the live site, alerts when a new tracker bypasses the banner, blocking covering local storage, fingerprinting and pixels as well as cookies, and the method published so an auditor can follow it.

Report an error

The Data Protection Officer

Tag gating is documented as a Google Tag Manager integration the site owner wires per vendor, with its limits explained — the warning that combining triggers drops cookies without consent, and the single-page-app limitation with a workaround — while the compliance monitor treats trackers fired before consent as violations and sends weekly alerts on misfiring tags, which is a real way to check nothing loads too early. We found no public information on an automatic blocking mode or maintained content blockers with placeholders; the captured video page only recommends collecting consent before launching embedded videos. 11 12 13 4

Scanning & cookie classification

How this is scored

How the product knows what the site sets: a scanner that crawls the site for cookies, local storage, pixels and third-party requests, scheduled rescans, a maintained database that classifies cookies and services by purpose, provider and lifetime, alerts on new or changed trackers, and a cookie declaration or policy section that updates itself from the scan.

0 — No scanning and no cookie list; every service is entered and described by the site owner from scratch.

3 — A one-off scan or a list of services the site owner fills in, with some predefined templates; scheduled scans, classification and the declaration are basic or not described.

5 — A scanner that finds cookies and third-party services on the site, regular rescans, automatic classification into categories from a vendor database, and a cookie declaration generated from the result and kept on the site.

8 — Scanning described in depth: scheduled scans with a stated depth or page count, scanning behind logins or in different regions, local storage and pixels as well as cookies, a large maintained database of services with purposes, providers and lifetimes, email alerts on new or changed trackers, and the declaration updated automatically in several languages.

10 — The cookie list stays true without manual work: continuous monitoring of the live site with a change history, unknown trackers flagged for review rather than silently classified, the classification sources and update process published, and scan reports exportable for an audit.

Report an error

The Data Protection Officer

The compliance monitor is documented in depth: a bot that scrapes the site, scans up to 20,000 pages, can scan behind logins and from a chosen country, categorises cookies, pixels and local storage into first- and third-party groups, runs on monthly or weekly schedules by tier, and alerts on new tracker activity, with audit-ready JSON exports and a time-stamped audit trail. We found no public information on a maintained classification database with purposes, providers and lifetimes, or a cookie declaration that updates itself in several languages. 4 13 14 5

Frameworks, signals & platforms

How this is scored

Where the consent goes and where the product runs: the IAB Transparency and Consent Framework (TCF, current version) with a registered CMP ID, Google Consent Mode v2 and Google's CMP certification, Microsoft UET consent mode and other ad-platform signals, the Global Privacy Platform and Global Privacy Control for US laws, plugins and apps for WordPress, Shopify, TYPO3 and other systems, iOS and Android SDKs, connected TV, multi-domain and agency accounts, and an API.

0 — No consent signal is passed on; other tools cannot read the visitor's choice.

3 — Consent readable through a cookie or a JavaScript variable, perhaps one CMS plugin; TCF, Consent Mode, app SDKs and multi-site management are basic or not described.

5 — Google Consent Mode v2 supported with the vendor named as a Google-certified CMP, IAB TCF supported, plugins or integrations for several named CMS and shop systems, a JavaScript API, and several domains manageable from one account.

8 — Signals and platforms described in depth: a registered IAB Europe CMP ID and the current TCF version, Google Consent Mode v2 in basic and advanced mode, Microsoft UET consent mode and other named ad signals, GPP and GPC for US states, iOS and Android SDKs documented, agency or partner accounts managing many client sites, and a REST API for configuration.

10 — One consent across every channel: web, apps and connected TV under one configuration, consent shared across domains and logged-in devices, every signal (TCF, Consent Mode, GPP, ad platforms) documented with its mapping to the banner choices, and configuration exportable or managed as code.

Report an error

The Data Protection Officer

The captured pages show IAB TCF v2.2, Google Consent Mode v2 with Google certified-partner status covering web, apps and connected TV, Microsoft UET consent mode, AWS consent mode, GPP and GPC, a documented REST API, and several domains manageable from one account. We found no public information on a registered IAB Europe CMP ID, basic versus advanced Consent Mode behaviour, CMS plugins for systems like WordPress or Shopify, or agency accounts managing client sites. 2 3 17 18 16

European sovereignty

How this is scored

Who the contracting entity and the parent company are, where the banner script is served from, where consent logs and scan results are stored, and who the subprocessors are (hosting, CDN, geolocation, scanner infrastructure, app SDK telemetry, email and support). Independently sourced by the sovereignty pipeline; a CMP runs on every page of the customer's site and sees every visitor, so the whole chain counts, not only the database. For a plugin that runs on the customer's own server, the vendor's licence, update and scanner services are the chain.

0 — Non-EU vendor and contracting entity, hosting unstated, subprocessors unnamed, and no data processing agreement offered.

3 — A privacy policy and a data processing agreement exist, but hosting location is unstated or non-EU and the subprocessors are not listed.

5 — EU hosting available and an EU contracting entity or EU representative, but parts of the chain (CDN for the banner script, geolocation, scanner, analytics, support) run through non-EU providers without a stated safeguard.

8 — EU hosting on named infrastructure, EU contracting entity, banner script and consent logs served and stored in the EU, subprocessors listed with their locations, a data processing agreement published, and security certifications (ISO 27001, SOC 2) stated.

10 — Sovereign end to end and evidenced: European ownership, entity, hosting, CDN and every subprocessor, or a self-hosted option that keeps the banner and the logs on the customer's own server; data export and deletion documented, and certifications published with their scope rather than implied.

Report an error

The Data Protection Officer

The contracting entity is proven European — Didomi SAS, 137 Boulevard de Sébastopol in Paris, registered with the Paris RCS under number B 831 722 756 — and the security page states ISO 27001 certification, encrypted point-in-time backups and replication across at least two physically separated data centres, with SCC and adequacy safeguards named in the privacy policy. But the captured pages state nothing about where the banner script and consent logs are served or stored, list no subprocessors and show no published data processing agreement; the legal notice names Amazon Web Services LLC at a Seattle address as host of the vendor's website. 7 6 8

Pricing transparency not rated — the vendor publishes no price

How this is scored

Whether a buyer can compute the real annual cost from public pages alone: price per domain or site licence, the page-view, session or consent limits of each tier and what happens above them, the free tier's limits, which features (TCF, app SDKs, A/B testing, multi-domain, white label) cost extra, agency or reseller terms, minimum term, and setup.

0 — No public prices at all; every customer is a sales call.

3 — A starting price or a free tier exists, but how cost scales with domains, traffic or features is unclear.

5 — Tiers are public with their price per domain or licence and their main inclusions, but at least one commonly needed piece (traffic overage, extra domains, TCF, app SDKs, agency use) is unpriced or "on request".

8 — Every tier priced publicly with its scaling rule (per domain, per page view or session band, per site licence), overage and extra domains priced, add-ons listed with prices, minimum term and VAT treatment stated.

10 — Complete price computability: annual cost derivable for a given number of domains, traffic and apps, with every add-on, setup, support, overage and agency fee and the cancellation and data-return terms published.

Report an error

The Data Protection Officer

All three tiers on the offers page — Essential, Advanced and Premium — are positioned with their scope but every one says "Contact us"; a free compliance monitoring scan exists, and tier inclusions such as unlimited domains based on monthly unique visitors, scan frequency and seat counts are published without a single figure. We found no public information on any price, visitor band, minimum term, overage or setup fee, so a buyer cannot compute an annual cost from the captured pages. 5 4 2
