Snowflake Horizon Catalog

Snowflake Horizon Catalog is Snowflake's built-in catalog and governance layer for discovering, securing and managing data, apps and AI models across the AI Data Cloud. It brings compliance, security, privacy, interoperability and access capabilities together so data teams can govern assets in one place instead of stitching together separate tools.

Horizon Catalog includes universal search for finding tables, views and marketplace listings, business context through descriptions and tags, automatic sensitive data classification, and lineage that shows how data moves between objects. Security features include masking and row access policies, trust center scanning of account security settings, and access history for auditing. It also supports open formats such as Apache Iceberg and can expose catalog information to external engines, allowing governed access beyond Snowflake itself. AI features help generate descriptions and answer questions about the catalog.

Data stewards and platform teams use Horizon Catalog to make trusted data easy to find, keep sensitive information protected, monitor data quality and prepare governed data for analytics and AI applications.
