The Dutch organisation managed to operate in secret for 35 years. Even the ministers were unaware of its existence. After the existence of the Italian Operation Gladio was revealed in November 1990, the then Prime Minister Ruud Lubbers confirmed the existence of a Dutch stay-behind organisation in a letter dated 13 November 1990 to the House Committee for Intelligence and Security Services .

Lubbers explicitly stated that the difference with the stay-behind organisations in some other European countries was that the Dutch organisation was not under NATO command. In the event of war and occupation, it would fall exclusively under the Dutch government in freedom. In his letter, Lubbers also pointed out a material and organisational difference between Gladio and the Dutch set-up. The Dutch organisation worked according to the 'single agent' principle, which does not lend itself to activities in groups under NATO leadership, which was apparently the case with the Italian Gladio. The Netherlands has always rejected this subordination to NATO.

At the time of the confirmation of the existence of the organisation, it was actually busy with downsizing due to the end of the Cold War. The organisation was formally dissolved at the beginning of 1992: for service A (formerly the O-branch) by a letter dated 13 March 1992 from Prime Minister Lubbers, for service B (formerly the I-branch) by a letter dated 3 April 1992 from Minister of Defence Ter Beek. The field staff of service B also received a letter of thanks from Prince Bernard. The winding-up lasted until 1994.
