In recent years, public-private partnerships (PPPs) specifically for prisons were often discussed but seldom implemented. The year 2025 saw a pivotal moment for Brazil, as Santa Catarina successfully established its own prison PPP, which symbolizes more than just a secured contract; it is a clear indicator of evolving institutional maturity in the country. This landmark decision has garnered attention because it highlights a progressive shift in involving private sectors in public security, while maintaining essential state functions like the power of coercion.

Historically, the prison system in Brazil has been influenced by other PPP models, particularly the one in Ribeirão das Neves, operated by GPA - Gestores Prisionais Associados for over two decades. This model has provided a template for other states to follow, showcasing how private involvement in prison services can be managed without outsourcing preeminent state responsibilities. The courage and pioneering spirit displayed by the government of Santa Catarina and GPA is noteworthy as it navigated the complexities of implementing a new approach to prison management and has established parameters that serve as a learning experience for others.

As with any innovative endeavor, this prison PPP has undergone adaptations based on practical experiences. Some original design choices, although made with good intentions, revealed unforeseen complexities that required adjustments. These lessons learned will be crucial for future projects aimed at reforming Brazil's prison system and enhancing public security through effective collaborations between public institutions and private entities.
