Just for the record, The General Data Protection Regulation (GDPR) is a new legal framework that sets guidelines for the collection and processing of personal information of individuals within the European Union (EU).
With Facebook being the biggest story in this space don't make the mistake that the new regulations won't affect you in Australia. Even if your server farm is located within Australia as a legal requirement, you'll soon have 'legal' knocking on your door asking about how secure your customer data is, and whether you comply with the new regulations. Don't forget that it's not just about where your data is stored, it's also where it's presented.
For those who have chosen to use Kentico as their platform of choice, the new version 11 has GDPR as one of its core feature upgrades.
Kentico has extensive documentation with all the details you require, however, the main features are consent management, consent tracking, right to access (gathering data from one point), the right to be forgotten and data portability.
Whatever version of Kentico you are on, Interesting can help upgrade you to the latest version and take care of all your data and GDPR needs.
