The providers of Xing and Kununu (both operated by XING SE, Dammtorstrasse 30, 20354 Hamburg, Germany) state if data processing takes places in the USA, they take care that it is performed in line with the requirements of Privacy Shield certification and that they will continue using the Commission’s standard data protection clauses in many cases.
