Dymium is a data security platform that provides real-time, zero-copy governed access to enterprise data for applications, analytics, AI agents, and GenAI systems. The platform operates as an enforcement layer—referred to as the "Ghost Layer"—that intercepts data requests and applies access policies based on identity, role, and context before returning any data to the requestor. The core architecture is built around three enforcement components: GhostDB (for database access), GhostAPI (for API-based access), and GhostMCP (for model context protocol access). These components apply policy directly at the data source without duplicating, staging, or copying data, which the company positions as an alternative to traditional ETL pipelines and shadow datasets. Key capabilities of the platform include: - Just-in-time, request-level access control with row, field, and role-level granularity - Real-time data masking, redaction, obfuscation, and filtering - Automatic logging and auditing of every data access request - Support for compliance frameworks including GDPR, HIPAA, and the EU AI Act - Governed data access for LLM prompts, agentic AI workflows, and BI/analytics tools Dymium targets multiple organizational personas, including data and AI teams, AI and product teams, security and risk teams, and privacy and compliance teams. The platform is designed to enable organizations to deploy generative AI, copilots, agents, and analytics without creating data sprawl or unmanaged copies of sensitive data. The company offers a SaaS product model with documentation, support, and demo request options available on its website.
