Tangany, a regulated fintech company, uses FusionAuth for its user management and OAuth 2.0 flows to authenticate partners in its B2B portal, addressing the complexity of regulatory hurdles financial institutions face when entering the digital asset market. Tangany's main clients are financial institutions, with solutions that simplify technical infrastructure challenges and ensure compliance with stringent regulatory requirements. The company has found FusionAuth to be a reliable authentication service that balances reliability, effort to integrate, feature set, and price, saving them time and money in early stages of production deployment. However, they still encounter challenges in monitoring audit and login logs within their self-hosted environment.
