The example of Wiki Leaks shows the sensation that the publication of secret data can cause. Especially in Germany, the topic of data protection is at the top of the attention agenda and should not be neglected in corporate communications. This not only affects internal data that is particularly exciting for competitors. Security gaps affecting customer data are particularly sensitive and always good for a crisis. Even though data security is a top priority in most companies, dealing with data leaks is a central issue in crisis PR. We advise you on the development of a communication strategy that takes effect quickly and provides transparent information in the event of a data leakage.
