Preventive Controls in the Modern Company: Evaluation and Assurance under the COSO Framework

In most organizations, financial errors, distortions in results, and fraud events originate from the way controls have been designed.
Policies, procedures, and validations do exist, but many of them operate too late, in isolation, or simply do not operate at all. The problem, therefore, is not the absence of controls, but their design.
This book is based on the premise that internal control must be an integrated structure that intervenes before risk materializes. Throughout the work, a technical model is developed based on the COSO framework, interpreted as a flexible architecture that enables the construction of coherent, traceable control systems aligned with business objectives. The reader will not find a mere enumeration of policies, but rather a design logic that connects objectives, risks, processes, decisions, and evidence.
Preventive Controls in the Modern Enterprise is intended for professionals who need to understand how to build systems that work in practice. Financial executives, auditors, internal control professionals, and operational leaders will find in these pages an applicable methodology to redesign processes, reduce residual risk, and strengthen the reliability of information.
Ultimately, the proposition is clear: it is not about detecting errors after they occur, but about designing organizations where, simply, they cannot occur.
