Onyx is a Swiss intelligence gathering system maintained by the Federal Intelligence Service - Nachrichtendienst des Bundes (NDB). The costs of the system are not public, but the amount of 100 million Swiss francs has been mentioned several times, in particular in 2000 by Werner Marti, SP deputy to the National Council of Switzerland. In March 2005, journalist Urs Paul Engeler estimated that the costs (hidden in various military construction budgets) reached 400 million CHF.
