True cookie compliance

Cassie approaches the complex issue of Cookie management from a new perspective! Cassie brings you the business benefit of being able to see a holistic single picture of a data subjects’ preferences and permissions whilst also giving you complete compliance.

Our cookie consent manager allows you to regain control of the cookies on your site, letting you publish only cookies that you approve. It also protects you against cookie stuffing with regular scanning to ensure your site is secure.

Enable users to accept, decline and change their preference about specific cookies making you compliant with GDPR & CCPA guidelines.

Centrally manage preferences

Cassie is so much more than Cookies, it enables the users Cookie consent preferences to be matched back to a data subject, giving you a 360-degree holistic and auditable view of your consent relationship.

Cassie also not only records Cookie permissions locally on a data subjects’ device, but also centrally for analytical use, giving you the competitive edge. Our Cookie module also offers granular opt out options, resulting in higher customer retention rates as your customers have choice.

Cassie can manage everything from Adobe preference landing pages to API preference calls.

Regain complete control

Either enable Cassie to manage cookie permissions in the traditional way other solutions use, by setting the values in sessions and Cookies themselves, relying on the script to check these before any action occurs, or reduce risk of certain activities by storing cookie scripts from third parties centrally within Cassie for deployment only after user agreement.

Also, because Cassie only deploys these scripts after user agreement, page speeds increase, enhancing your customers online experience.

Maximise your security

Cassie regularly inspects any hosted Cookie scripts to warn of payload increases, along with activities that could indicate a security breach. This could be scripts that copy data being entered to unusual locations.
