Custosa

Custosa fortifies enterprise applications by implementing granular access control before sensitive data reaches the processing model. Key features include: • Upstream permission enforcement • Dynamic context compilation based on user identity • Real-time compliance policy integration • Support for RAG and agentic pipelines • Reduction in token usage (30-50%) This platform addresses the quiet vulnerability in enterprise deployments where models might access unauthorized information like contracts, patient records, or classified specifications. Custosa ensures that context is filtered based on who is asking and what they are allowed to see, rather than relying on post-output filters. It compiles access rules at runtime from user identity and compliance policies, delivering different, policy-approved contexts for the same query depending on user clearance. Custosa is built to be HIPAA, ITAR, and SOC2 compliant, making it an essential layer for organizations in regulated industries such as healthcare, aerospace, and finance. By sitting between enterprise data and models, it allows companies to ship secure applications without losing valuable context, thereby accelerating deployments and mitigating data leakage risks. The platform is model-agnostic, integrating seamlessly with existing retrieval-augmented generation (RAG) and agent stacks.
