Northern Portugal: a distributed network
Northern Portugal brings together a diversity of realities that demands a local presence in various locations — the university and historical hub of Braga and Guimarães , the coastal strip of Viana do Castelo , and the inland region of Trás-os-Montes, including Vila Real and Bragança .
That's why we don't centralize operations in a single city : we maintain agents distributed throughout the region, coordinated with each other, to guarantee the same quality and speed of response in any municipality.
Regional Coverage and Proximity
A fundamental base for our coverage in Minho and Cávado, serving as our command center for the entire northern coastal area.
We understand that the effectiveness of an investigation depends on the speed of intervention and knowledge of the terrain. We operate from three main operational centers, covering the entire coast and northern interior :
