4 sites, 8 languages, fully unified consent-preference management.

For a large group like Acteon — present in dozens of countries with a nerve centre in the European Union — the compliant handling of personal data is critical. In its drive for full GDPR compliance, Acteon’s multi-site, multi-language structure poses a real architectural challenge.

You have to manage consent persistence across several domain names — acteongroup.com, acteonmedical.com, acteonveterinary.com, acteon-club.com — and the multi-language context (8 possible languages).

The approach

We audited several CMPs to find the best fit. We chose abconsent, the CMP from Sirdata (a French company), because it handles these scenarios while being strict about applying current legal obligations.

The entire CMP configuration and rollout were centralised in GTM.

A useful side effect

A QA audit revealed that the CSP — very strict across the group’s sites — was blocking some CMP features in certain languages. That let us, along the way, fix CSP issues for several tags and platforms.

The result

Unified consent management across 4 domains and 8 languages, centralised and maintainable from GTM — and solid GDPR compliance for the whole group.
