Freedom is, was and will always remain important. This applies to our physical world as well as our digital world. To maintain our freedom we need protection and good IT security. Good security brings freedom the way you want and enables you to exchange information without censorship or monitoring. Your secret information and your communication belongs to you. So take measurements to make is yours again.
Privacy needs solid security to start with, but if you value your own freedom, you should respect your customers freedom too. So make sure your users can trust you. So respect their privacy by using tangible privacy measurements by design principles when creating new solutions.
Good security and privacy do not have to be endlessly expensive. It all starts with good architecture and a solid design.

Good protection for our privacy is getting more and more difficult and expensive. In our opinion freedom requires very strong privacy protection assurances. We do not live a world where cyber security is always at a normal (low) risk level. You need more protection measurements by default to protect your core information assets like personal and business information and your valuable privacy data records. We still have a long way to go. But using solutions provided in this reference architecture lowers your security and privacy risks.
For privacy and security we need strong governance institutes that set rules to keep our (online) freedom.
