CYBERSECURITY INFRASTRUCTURE OPTIMIZATION IN ENGINEERING ENVIRONMENTS: A CASE STUDY AT GENTILE ENGENHARIA

This paper provides an expanded analysis of a cybersecurity infrastructure optimization project conducted in
2023 at Gentile Engenharia, a mid-sized engineering firm located in São Paulo, Brazil. The organization
experienced accelerated digital expansion between 2022 and 2023, which exposed systemic vulnerabilities
including flat network topology, inconsistent security controls, legacy protocols, and ineffective firewall
governance. To address these issues, the internal IT team executed a structured modernization plan involving
firewall policy redesign, segmentation of network architecture, server consolidation, and alignment with
international cybersecurity frameworks. The intervention improved system resilience, reduced operational
incidents, and established a scalable foundation for information security governance. These findings offer
practical insights for engineering companies undergoing similar infrastructure growth.
