Comparison of 9 leading consent management platforms

GDPR set a gold standard for data privacy regulations, especially with the requirement to collect explicit consent from users prior to processing their personal data. 

The law has served as an inspiration for other countries. For example, Brazil’s LGPD and California’s CCPA borrow heavily from GDPR.

Most data privacy regulations share one goal – to give individuals more control over their personal data. At the same time, with the growing importance of web and mobile analytics, organizations have to take privacy compliance seriously. 

With a consent management platform (CMP), consent collection and management is easier and more transparent. 

“People are actively demanding privacy protection — and legislators are reacting. If your organization operates globally, focus on standardizing operations in accordance with the GDPR, and then adjust for local requirements.”

Bart Willemsen, Vice President and Analyst at Gartner

Learn more about Piwik PRO Consent Manager.

A consent management platform is a piece of software that helps you collect and manage personal information and consent in line with data protection laws and regulations like the EU’s GDPR, California’s CCPA, or Brazil’s LGPD.

With a consent management platform, you can display consent banners and pop-ups to users. It enables you to gain insight into the user’s personal data lifecycle from the moment of opt-in to the moment of data removal.

Piwik PRO Consent Manager Platform

CMP tools give users detailed information on how their online behavior may be tracked, the purposes for which that information is collected, and the specific entities that will use it. Users can choose if they want to grant, refuse, or revoke consent to having their data collected for any specified purposes. 

A CMP also helps you fire tags based on users’ consent decisions and prevent them from running before you obtain legal consent.


Comparison of the 9 leading consent management platforms

Compare the 38 key differences to determine which CMP fits your business needs: Piwik PRO, TrustArc, OneTrust, Cookiebot,, Tealium, Quantcast, Crownpeak and UniConsent.

As with selecting any kind of tool, you need to see what deployment options are available, what resources you have, and what the key requirements are to make it work.

Below, we list some things that you should consider in the decision-making process:

Privacy and compliance

Since a consent management platform is supposed to streamline your compliance efforts, look into the privacy aspects of the CMP you go for, such as:

  • Does the CMP offer flexible data residency options? For example, if you process data of EU residents, make sure it is stored in the EU and not transferred overseas. 
  • What privacy regulations does the CMP help you address and how? Beyond laws that require valid user consent in most cases, there are regulations like the French CNIL or German TTDSG that you can observe by applying zero-cookie load. If you fall under these laws, look for a CMP that offers this feature.
  • Does the CMP offer different tracking methods? For example, anonymous tracking can help you satisfy compliance requirements by not collecting personal data without consent but still gathering valuable insights.


Inspect the options for integrating your consent collection channels to ensure a smooth, secure, and synchronized data flow. Make sure that all customer actions – consents, preference changes, unsubscription requests, and data subject access request logs – are consistently reflected in all systems.

You should also check if the consent management platform can be connected with a tag management system or customer data platform. This way, you can adjust settings in these tools to respond based on users’ consents.


Consider the customization options. How easily can marketers adjust the wording and appearance of opt-in banners and forms? Can you perhaps design and connect your own fully customized consent banner? Your consent banner should reflect your site’s or app’s design and branding.

Technical requirements

See whether the setup and maintenance of your consent manager require you to devote technical resources. If you don’t want to rely on developers, choose a platform that can be managed even by less technically adept specialists.
