Comparison of 10 leading consent management platforms

GDPR is the 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 legislation such as Brazil’s LGPD, California’s CPRA, Canada’s CPPA, and Germany’s TTDSG/TDDDG.

In the report by Gartner, it is expected that by 2024 75 percent of the global population will be covered under modern privacy regulations. The forecast for the year 2023 was 65 percent, up sharply from only 10 percent in 2020.

Most data privacy regulations share one goal – to give individuals more control over their personal data. At the same time, with the growing awareness of the importance of privacy rights amongst users, organizations have to take privacy compliance seriously. Users want to know what information is being collected about them. That’s why companies need to precede their marketing activities with user consent if they’re going to build relationships based on trust.

A consent management platform (CMP) makes consent collection and management easier and more transparent.

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.

With a consent management platform, you can display consent banners and pop-ups to users. Cookie consent pop-ups 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 whether to grant, refuse, or revoke consent to collect their data for any specified purpose. 

CMPs enable you to gain insight into users’ personal data lifecycle from the moment of opt-in to the moment of data removal.

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

Selecting the right CMP needs careful consideration. You should see what deployment options are available, what your resources are, and what the key requirements are to make it work.

In the selection of a consent management platform, focus on its ability to provide clear and concise consent options to users, ensuring compliance with legal requirements like GDPR and CCPA. It’s important to choose a platform that offers detailed reporting and analytics, helping you understand user preferences and consent patterns. Also, consider the vendor’s reputation, customer support, and the community or resources available for ongoing guidance in the ever-changing data privacy field.

Below, we list some things you should consider when seeking a consent management platform that suits your business needs.

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. 

You can ask a few key questions:

  • Does the CMP offer flexible data residency options? For example, if you process data of EU residents, it might be a good idea to store the data in the EU and not transfer it overseas. 
  • What privacy regulations does the CMP help you address and how? Beyond laws that require valid user consent, there are regulations like the France’s CNIL or Germany’s TTDSG/TDDDG that you can observe by applying zero-cookie load. If you’re subject to these laws, look for a CMP that offers this feature.
  • Does the CMP support 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.

Ensure that the CMP you choose complies with relevant data privacy regulations in your jurisdiction. Look for platforms that offer features specifically designed to help you comply with these regulations, such as granular consent options and documentation capabilities.


Evaluate the integration capabilities of the CMP with your existing systems and workflows. Look for platforms that can integrate easily with your website, mobile apps, and other digital properties, as well as with your data management and marketing automation tools.

Inspect the options for integrating channels that need consent collection 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, if you use one. This way, you can adjust settings in these tools to respond based on users’ consent.


Look for a CMP that allows for flexibility and customization to tailor the consent collection process to your specific needs and preferences. This includes the ability to customize consent banners and dialogs, as well as the flexibility to adjust consent preferences and settings based on evolving regulatory requirements or organizational policies.

Consider the customization options:

  • How easily can marketers adjust the content and appearance of opt-in banners and forms? 
  • Can you design and connect your own fully customized consent banner if needed? 

Make sure that your consent banner allows you to reflect your site’s or app’s design and branding.

Technical requirements

See whether the setup and maintenance of your consent manager requires technical resources. If you don’t want to rely on developers, choose a platform that can be managed even by less tech-savvy people.

Consider the scalability of the CMP to accommodate changes in your organization’s needs and growth over time. Choose a platform that can scale with your business, whether you’re a small startup or a large enterprise, and that can handle increasing volumes of consent transactions as your user base grows.

Evaluate the level of support and maintenance offered by the CMP provider, including availability of customer support, documentation, training resources, and software updates. Choose a provider that offers responsive and reliable support to help you troubleshoot issues and stay up-to-date with changes in regulations and best practices.
