A CMP is a tool to help manage compliance within the IAB Europe’s Transparency and Consent Framework (TCF) and GDPR. A CMP empowers domain owners to obtain, manage, and propagate consumer consent to share their cookie data on the site or with associated vendors.
GDPR is the primary EU regulation on data protection and privacy. IAB TCF is the only GDPR consent solution built by the digital advertising industry for the industry.
Note: Quantcast no longer provides a CMP. You will need to find another CMP tool.
Why use a CMP, not a cookie banner?
Publishers and marketers should use a CMP built on the IAB TCF to ensure it covers their sites' businesses with 3rd-party vendors, not just their own.
Traditional cookie banners may not provide the unambiguous, granular consumer consent required by the GDPR. In addition, cookie banners generally do not propagate any consent signal to the downstream vendors. Unlike cookie banners, a CMP provides the consent audit trail central to the GDPR’s requirements.
What does a CMP do?
There are four core CMP functions:
Consent Notification: provides consumer notices for collecting and processing personal data
Privacy Preferences: provides consumer options to exercise consent and legitimate interest preferences at granular levels
Signal Capturing & Sharing: captures consumer preferences in an IAB-compliant consent cookie to share with approved partners
Proof of Compliance: Ability to access the audit log for implemented CMP
