Ever more it is observed how much corruption causes immeasurable impacts for the social and economic development ofthe country. In addition, it causes damage to the reputation of individuals and companies. Combat it depends on everyone and especially the companies, which have a relevant role in this scenario. In this sense, this applied work has as panorama the Brazilian context of the anticorruption law and the Integrity Program required to the companies taking into account the issues of culture, organizational climate and leadership. 'The prevention of corruption must be seen as an integrated action of several instances and levels of management of a company [...] that enable greater individual, collective and institutional commitment' (MACHADO, 2015, p.17), the present work aims to answer the following research question - How do Brazilian infrastructure companies conduct their integrity programs? For this, a case study was carried out from a qualitative analysis. The data analyzed lead us to infer that the actions of the Integrity Program carried out by the company have followed the guidelines of the Union Comptroller's Office (CGU), however, given the indicators obtained in the Sustainability Reports, it is understood that the data are insufficient for an analysis of the implemented Program. When comparing the Program carried out by the company with the Anti-Corruption Law and the guidelines of the CGU, it been included the necessary items. However there is an opportunity for improvement with respect to its application in relation to leadership development and training actions. Although restricted to a single organization, the results can be a source of information for companies to grasp the issue and act in a way that ensures a balance of sustainability and improved competitiveness. However, this research does not seek to generalize the results, but rather to contribute to the reflection on the possibilities, both for the organizational interventions and for the research development.
