FusionAuth is a popular authentication platform used by various companies, including Inteligov, a SaaS solution that helps private organizations monitor political and regulatory risks in Brazil. Inteligov's CEO, Raphael Caldas, uses FusionAuth to manage authentication for his company's client-facing applications on the web and mobile apps, simplifying handling multiple applications with users having a single login. The platform provides social sign-on capabilities and allows for easy implementation of custom enterprise authentication solutions. Before adopting FusionAuth, Inteligov was using traditional libraries for authentication with email/password, and it has significantly reduced their time and money spent on authentication. Raphael attributes the choice to FusionAuth to its cost-effectiveness, functionality, and active community.
