Consent Management Software Buyer’s Guide

Today, more people are worried about their privacy. A study among 10,000 adults across 10 countries shows that 80%of adults are worried about their privacy. From an organization’s standpoint, this translates to customer expectations and concerns about how the organization handles personal data. This concern about data privacy is further accentuated by the emergence of stringent guidelines like GDPR and CCPA that mandate organizations to take measures to protect the privacy of their customers.

Below are some of the best consent management software that can work well for almost any organization, regardless of its size and industry:

  1. BigID A CMP that uses advanced machine-learning algorithms and next-gen AI to provide a centralized view of your consent data.
  2. Transcend Consent A highly customizable consent management platform that automates the display and collection processes across all interfaces.
  3. Cassie A centralized consent management tool that can handle high-volume and complex consent data from anywhere in the world.

A key component of data privacy is consent management. It is a set of processes that allow customers to decide if they want to share their data with a business. Often, the business has to state how it will use the customers’ data. Based on this information, individuals can choose to share their data. For example, article 7 of GDPR states that the organization must present the request for consent in an accessible form using clear and plain language. Also, the individual must understand the consent and explicitly agree to the processing of his or her data. More importantly, the user must have the option to withdraw consent at any time.

In other words, individuals knowingly consent to providing their data so that organizations can use them for specified purposes. This consent management is a cornerstone of data privacy, and organizations that fail to provide consent management can face heavy fines and penalties. To address this requirement, organizations use consent management platforms to collect and store consent from users seamlessly.

In this guide, we will talk about what are consent management platforms and what factors to consider while selecting the right one for your organization. Also, we will briefly talk about the popular consent management platforms available today.

What are Consent Management Platforms?

A Consent Management Platform (CMP) is software that displays your organization’s data usage and privacy policy, requests consent, collects it from users, and stores and handles this consent per the data protection laws. Moreover, the platform must always provide users the option to withdraw their consent at any time, as per GDPR requirements.

The advantage of using a CMP is that it automates the process and makes the entire consent management smooth and efficient. Also, it helps organizations meet the specified regulations with no additional resources.

Though different CMPs can have minor variations, they all are likely to have the following features.

  • A consent banner containing the data processing policies of your organization is displayed to every visitor on your website or app.
  • The banner will also explicitly request the user’s consent.
  • The user will have the option to allow only a part of their data for processing.
  • This software also stores these preferences to allow users to edit or withdraw them anytime.
  • It provides an auditable trail of all consent-related activities.

Now comes an important question. If every CMP has similar features and implementation, how can you choose one over the other?

Read on to get the answer.

How to Choose a CMP?

While choosing a CMP, consider the following aspects.

Comprehensive and Full-Stack

There is a common misconception that consent is for cookies only. But the reality is that it extends all through your tech stack. Ideally, you’d want a tool that enforces consent preferences from the client interface to the backend processes, touching every connected system and data store. Such a comprehensive approach prevents non-compliance.

Focus on Notifications

Notifications are an essential part of consent management. Besides informing users about their content preferences, the tool must also ensure these details are present in the privacy policy. Sometimes, it even helps to have a pop-up window that clearly explains data processing.

User Experience

Though it is important to collect consent, your chosen tool must also consider user experience. It must provide a smooth flow and ensure that the user experience is not disrupted in any way. Also, the tool must have a single touchpoint to display and collect consent instead of popping a window now and then. Similarly, the tool must avoid repetitive banners.

Granular Control

Users must have the option to granularity control what aspects of their data are open for processing. Consent management must not be an allow-all or deny-all option, as this can impact user trust and business outcomes.

Continuous Visibility

Your chosen CMP must provide complete visibility into the consent gathering and handling processes. Staying on top of how these tools tag individual consent and handle requests for edits and deletes is key to ensuring compliance.


Well-designed dashboards and out-of-the-box reporting templates help audit your consent management practices. Moreover, its audit trail and logging capabilities enable you to confidently manage consent across a global audience.


Scalability is another key consideration. As you expand your digital footprint, the CMP must automatically cover them. This seamless scalability can ease your expansion while meeting compliance.

Thus, these are some features to look for while deciding on a consent management platform.

To further ease your efforts, we evaluated different tools on the above factors to create a list of the best ones.
