Axiomatics Policy-driven Authorization is an externalized authorization solution that provides fine-grained access control through centralized policy management. The platform enables organizations to implement attribute-based access control (ABAC) for securing sensitive data and applications. The solution addresses access control challenges including online payment authorization, delegation management, relationship management and conflict of interest prevention, anomalous behavior detection and response, secure data sharing, separation of duty enforcement, and access reviews and recertification processes. The platform externalizes authorization logic from applications, allowing for centralized policy definition and enforcement across multiple systems. It supports context-aware access decisions based on attributes such as user identity, resource characteristics, environmental conditions, and organizational policies. Key capabilities include granular access control at multiple levels, compliance support for regulations including GDPR and PSD2, real-time policy evaluation, and integration with existing identity and security infrastructure. The solution is designed to work with APIs, microservices, and various application architectures. The platform follows Zero Trust principles by evaluating every access request against defined policies. It enables organizations to streamline application development by removing authorization logic from application code and managing it through centralized policies.
