Prefeitura de Porto Nacional

Prefeitura de Porto Nacional is the municipal government of the city of Porto Nacional, located in the state of Tocantins, Brazil. As a local public administration entity, it is responsible for delivering essential services to residents, including urban planning, public works, health and education support, and the collection of municipal taxes. The organisation also manages internal information technology systems that support day‑to‑day operations across various departments. Among these systems are geomapping services that provide spatial data for planning and infrastructure management.

The municipality reported that its IT environment holds approximately 20 terabytes of data, a figure disclosed during the ransomware incident of 23 June 2025. This data volume reflects the scale of digital information the administration maintains for operational and service‑delivery purposes. The organisation’s headquarters are situated in Porto Nacional, serving as the central point for administrative coordination within the municipal boundaries. Its reach is confined to the geographic jurisdiction of the city, focusing on the needs of the local population.

A distinguishing attribute of Prefeitura de Porto Nacional is its role as a regulatory authority that enforces municipal legislation and oversees compliance with state and federal laws applicable to local governance. The reliance on daily backups, as evidenced by the recovery process following the ransomware attack, highlights a disciplined approach to data resilience and continuity planning. Structurally, the prefeitura is a public sector entity subordinate to the government of Tocantins and ultimately to the federal Brazilian administration, with no private ownership or parent‑subsidiary relationships disclosed in the available information.
