The paper reports results of a study aimed at the development of recommendations for harmonization of table protection in the German statistical system. We compare the performance of a selection of algorithms for secondary cell suppression under four different models for co-ordination of cell suppressions across agencies of a distributed system for official statistics, like the German or the European statistical system. For the special case of decentralized across-agency co-ordination as used in the European Statistical System, the paper also suggests a strategy to protect the data on the top level of the regional breakdown by perturbative methods rather than cell suppression.
