Leading European Lottery Organization

… Dr Tournis was in charge of a team that delivered an Integrated Security Program for our company. This program was one of the biggest and most complex in our market, not only due to its size but also due to our specific business model, and was delivered without any deviations whatsoever, within schedule and according to its specifications.
During our collaboration, SIGMA team demonstrated their excellent professionalism and cooperation spirit, contributing effectively in the successful implementation of the program. They left us with the best impressions with regards to their know-how and character.
We would unconditionally recommend the use of SIGMA services to anyone interested in their services portfolio.
