Engineering teams are grappling with increasingly complex authorization requirements as digital products evolve to be more collaborative and AI-enhanced, creating a need for a unified approach to authentication (AuthN) and authorization (AuthZ). FusionAuth, which already provides robust identity management, has acquired Permify to address these challenges by integrating fine-grained authorization capabilities such as Attribute-Based Access Control (ABAC) and Relationship-Based Access Control (ReBAC) into its platform. This integration aims to solve issues of fragmentation, duplication, and latency that arise from using separate systems for AuthN and AuthZ, while also ensuring that modern authorization demands, including those driven by AI, are met efficiently. By combining their technologies, FusionAuth and Permify offer a comprehensive solution that enhances performance, scalability, and security, allowing developers to focus on building advanced features without the burden of managing complex permission systems. The integrated product promises to unify identity and authorization controls, simplifying compliance, accelerating development, and addressing intricate access control challenges across industries.
