This paper explores internal control models from countries with a greater level of transparency as per International Transparency's Corruption Perceptions Index. Our intent is to understand the relation between the models’ dynamics and their prestigious position within the phenomenon of corruption. Important Colombian entities from the public and private sectors were interviewed and surveyed in the following categories: internal control model, risk management, internal control culture and corruption. The results are in keeping with the country’s reality, which was compared with that of more transparent countries. We concluded that there are flaws, opportunities, strengths and threats in internal control systems in Colombia both in the private and public sectors. Likewise, we found cultural aspects related to values and a need for master’s degrees.Keywords: Model of Internal Control, Internal Control System, Fraud, Risk, COSO, MECI.
