Business Case: Cookie Consent Management

Eva Unverferth


Implementation of cookie consent management for 500+ websites in less than six months for GDPR/ePrivacy compliance, further deployment and optimization after initial implementation


The General Data Protection Regulation (GDPR) and ePrivacy Directive require that website owners must obtain user consent from website visitors from the EU before installing cookies that are not strictly necessary for making a website work. Similar laws are in place for the UK with the Privacy and Electronic Communications Regulations or for Brazil with its Lei Geral de Proteção de Dados Pessoais (LGPD) and in preparation for countries like Canada, Switzerland and India.

What are cookies? Cookies are small text files that are sent to the computer when visiting a website. Cookies are used for storing, for example, your language preferences, your credentials for letting you return to a protected area without entering your credentials again or your shopping cart in an online shop to let you continue a shopping tour after having temporarily left the online shop. Besides those functional (and very useful) cookies, there are also so-called performance cookies that track how you use a website to allow the website owner to optimize, for example, marketing campaigns and targeting cookies that store information about your website visits for advertisement reasons.

Cookie banners were being implemented already for years. However, website visitors were just informed that the website is using cookies and that by continuing the website visitor accepts this. This is not compliant with the above “cookie laws”. They require to

  • Receive users’ consent before implementing any cookies except strictly necessary cookies
  • Provide accurate and specific information about the data each cookie tracks and its purpose in plain language before consent is received
  • Document and store consent received from users
  • Allow users to access the website even if they refuse to allow the use of certain cookies
  • Make it as easy for users to withdraw their consent as it was for them to give their consent in the first place

Being uncompliant with cookie laws puts organizations at significant financial and reputational risk. The first cases were seen in France in December 2020 when the French data regulator (CNIL) fined Google 100 million euros for not compliant cookie management and Amazon for 35 million euros for automatically placing advertisement cookies when visiting

The initial situation with our customer was that a cookie consent management tool (SaaS) had been selected and implemented for some corporate communication sites. However, the implementation scope was not clear as no accurate website inventory was available. Furthermore, the capabilities for a quick and resource-saving implementation while ensuring that no new websites go live without proper cookie consent management were not available.
