Buying a Consent Management Platform is only the first step. A CMP that is misconfigured, outdated, or incompatible with your tag manager can still allow analytics and marketing cookies to drop before consent. The result is a false sense of compliance and continued GDPR risk.

The CMP Configuration Checker detects which platform is active, Cookiebot, OneTrust, Didomi, Usercentrics, Complianz, Klaro, Osano, and many more, then simulates user consent choices to verify that the banner actually blocks the categories it claims to block. It identifies missing categories, incorrect geolocation rules, and scripts that bypass the CMP entirely.

This feature is especially valuable after CMP updates, template changes, or marketing tag additions, when configuration drift is most likely. Instead of assuming the banner works, you get empirical proof of its blocking behavior.
