3. Security measures according to Art. 32 DGGVO

a) In order to ensure an appropriate level of protection, we take into account the implementation costs, the state of the art and the type, scope, circumstances and purposes of processing as well as the different probability of occurrence and severity of the risk for the rights and freedoms of natural persons, suitable technical and organizational measures. This includes, in particular, securing the confidentiality, integrity and availability of data by controlling physical access to the data, as well as the access, input, transfer, ensuring availability and their separation. We have set up procedures that guarantee the exercise of the rights of data subjects, the deletion of data and a response to data threats.

5. Transfer to third countries

Subject to legal or contractual permissions, we only have data processed in a third country outside the European Union (EU) or the European Economic Area (EEA) if special conditions are met in accordance with Art. 44 ff. GDPR, e.g. on the basis of officially recognized guarantees that that a similar level of data protection as in the EU is observed.
