Research Specialties at the Center
The Central Region combines a diversity that few regions in the country possess — the university and judicial hub of Coimbra , the industrial and port activity of Aveiro , the tourist coast of Leiria , and the more rural interior of Guarda and Castelo Branco . This breadth requires a distributed network of agents, with shared coordination between the various units and in-depth knowledge of each sub-region.
Frequently Asked Questions
1. Do they cover the entire Central Zone, or just the main cities?
We cover the entire district, from the coast to the interior — Coimbra, Aveiro, Leiria, Viseu, Santarém, Guarda and Castelo Branco, with the same standard of response anywhere in the region.
2. How is the operation coordinated in this region?
Our network of agents in the Central Zone works in a coordinated and distributed manner, guaranteeing the same standard of quality and technical rigor at any point in the region — without depending on a single central office.
3. How much does an investigation cost in the Central region?
We do not work with hourly rates or a public price list. We provide a fixed price after a free initial assessment, with travel within the region already included.
4. Do they conduct research related to academic communities in the region?
Yes, especially in Coimbra and Viseu, where we frequently receive requests for remote family support related to university life.
5. Do you work with industrial and port companies, for example in Aveiro?
Yes, it's a significant part of our work — unfair competition, information leaks, and monitoring sick leave in an industrial setting.
6. Do you conduct investigations involving smaller cities, such as Tomar or Caldas da Rainha?
Yes, our network of agents allows us to extend coverage to neighboring municipalities of the region's main cities, without excessive travel costs.
7. Do I need to travel to Coimbra to open a case?
It's not mandatory. The process can begin by phone, video call, or email, with the same contractual formality, regardless of your location in the region.
8. Do they conduct electronic sweeps in any city in the Central Zone?
