The record

Purpose: The Semantic Layer defines business meaning once so teams, systems, BI tools, APIs and AI agents can use a shared governed model.
Ontology: It models business entities, relationships and rules in formal ontologies, with AI assistance for ontology creation and maintenance.
Schema mapping: AI-assisted automapping maps ontology classes to physical tables and columns, and flags affected mappings for review when source schemas change.
Data movement: The Semantic Layer is built over existing infrastructure without moving or replicating data.
Consumers: The governed semantic model is exposed to BI tools, APIs, AI agents and the Data Marketplace.
AI context: AI agents using the Semantic Layer inherit business context, terminology and rules.
Regulatory frameworks: Stratio says one ontology can support independent governed views for frameworks including IFRS, Basel IV and DORA, and says GDPR-related access can be logged with identity and purpose.
Security certifications: Stratio says it is certified under ENS High, ISO/IEC 27001 and ISO/IEC 42001, and aligned with GDPR, NIS2, the EU AI Act and DORA.
Deployment: Stratio offers SaaS hosted by Stratio, SaaS in a customer cloud account, and on-premise deployment, including air-gapped environments.
Cloud support: Customer-cloud deployment supports AWS, Azure, GCP and OpenStack.
Who it is for: Stratio describes the platform as built for regulated organisations, including banking, insurance, manufacturing, telecommunications, energy and the public sector.
Sales and support: The product page invites prospective customers to see a demo or talk to the team; it does not list a public support tier.
Headquarters: Pozuelo de Alarcón, Madrid, Spain
