How to get licensed

No licence is needed, so start by registering the activity: declare início de atividade with the Autoridade Tributária as a sole trader, or form a company (e.g. through Empresa na Hora)
- 2
Set up GDPR compliance for case files and surveillance data (supervised by the CNPD)
- 3
Check that services do not fall under Lei 34/2013 (guarding, close protection, alarm monitoring), which would need a private security licence
