Meridian AI Platform (DEMO) is a multi-tenant artificial intelligence service delivered to federal agency customers. Agency users submit documents and structured records for analysis, run retrieval-augmented question answering over their own corpora, and consume classification, summarization, and extraction results through a web portal and a REST API. Per-tenant isolation is enforced at the application, inference, and data tiers, and no tenant's content is used to train or fine-tune models serving any other tenant.

DEMO is offered as Software as a Service and is deployed exclusively in government-only cloud environments. Data processed by the service includes agency documents submitted for analysis, the vector embeddings derived from them, inference requests and responses, user profile and authorization data, model artifacts and versions, and the audit logs generated by user, administrative, and inference activity.

The service is pursuing FedRAMP 20x Class C certification at the Moderate sensitivity tier. Compliance and continuous monitoring for DEMO are operated in Stratus GRC-ITSM (HALOGRC), the GRC and IT service management platform the organization uses to run its security operations. Asset inventory, vulnerability and POA&M lifecycle, change management, access reviews, incident response, and Key Security Indicator validation all execute as ticketed work in HALOGRC, so the evidence supporting this authorization is produced by the operational record rather than assembled separately for assessment.
