It regularly happens that personal data or other sensitive information such as temporary passwords, application documents etc. need to be transmitted quickly.

In our digital age, digital data has become the most valuable asset. Every click, every search query, every ‘Like’ are collected and analysed. For many companies, this data is of inestimable value, for example in order to better understand target groups, place personalised advertising, etc. However, while companies can use this data to boost their business, criminals also have a keen interest in such data, as any of this information can potentially be used to cause harm. From identity theft to financial losses – the risks are numerous. Protecting your own data is therefore more important than ever before. In this blog post, we would like to give you a few suggestions on how you can protect your privacy on the internet.
