> Atlan is hosting Context Conference, bringing together the leaders and builders at the frontier of giving AI the context it needs to understand their business. It runs online on October 28, 2026, from 11:00 AM to 2:00 PM ET. Atlan co-founder Prukalpa Sankar opens and closes the day. Leaders from AstraZeneca, BNY and Verizon share why they invest in context and what they get from it. Registrants get early access to The AI Context Gap, a new study from MIT Technology Review Insights. Register: https://atlan.com/context-conference/

**Snowflake Horizon + Atlan: unified context and cross-platform governance for future-ready AI use cases.** Snowflake Horizon Catalog provides built-in context and governance for AI in Snowflake. Atlan extends that context and governance across your entire data stack to drive future-proof AI use cases for both technical and business teams.

"Atlan is much more than a catalog of catalogs. It's more of a context operating system...Atlan enabled us to easily activate metadata for everything from discovery in the marketplace to AI governance to data quality to an MCP server delivering context to AI models." - Sridher Arumugham, Chief Data and Analytics Officer, DigiKey

## Atlan adds capabilities, extends them to more systems and user types

Snowflake Horizon Catalog provides the governance foundation within Snowflake. Atlan extends trust, context, and control across your entire data stack.

- **Enable federated, interoperable, multi-platform control plane:** Horizon catalog governs Snowflake, and Atlan extends those controls across the heterogenous stack of cloud platforms, BI tools, ETL tools and SaaS solutions.
- **Make data usable for everyone:** Horizon serves technical users, while Atlan brings a consumer-grade experience to every persona: engineers, analysts, stewards, business users, and AI agents.
- **Trace the end-to-end data journey:** Horizon delivers lineage in Snowflake, and Atlan extends that visibility across sources, transformations, and dashboards for column-level, end-to-end trust.
- **Advanced governance for enterprise needs:** Horizon offers tagging and access controls, and Atlan adds governance workflows, policy manager, and rule-based playbooks for enterprise-wide governance.

## Why is Atlan the best universal catalog for Snowflake Horizon?

1. **Enterprise-wide adoption:** extends assets from Snowflake to every persona by embedding metadata into everyday tools and curating assets into business-ready data products. [Personalization and curation](https://atlan.com/personalization-and-curation/)
2. **Faster time to value through automation:** no-code Snowflake setup in under 30 minutes. Playbooks and Atlan AI automate tagging and governance with a 70% suggestion acceptance rate. [DIY setup](https://atlan.com/diy-setup/)
3. **Deep, two-way integration with Snowflake:** bi-directional tag sync keeps policies aligned between Atlan and Horizon and automates masking and compliance across systems. [Snowflake setup docs](https://docs.atlan.com/apps/connectors/data-warehouses/snowflake/how-tos/set-up-snowflake)
4. **End-to-end lineage across the enterprise:** connects Horizon lineage across sources, pipelines, and BI for column-level, end-to-end visibility. [Column-level lineage](https://atlan.com/column-level-lineage/)
5. **Partners in innovation with Snowflake:** Atlan is the 2025 Snowflake Data Governance Data Cloud Product Partner of the Year, and a launch partner of Snowflake Open Semantic Interchange and Snowflake Intelligence. [Snowflake Intelligence partnership](https://atlan.com/know/snowflake-intelligence-atlan-partner-talk-to-data/)
6. **Future-proof for data and AI:** an Iceberg-native metadata lakehouse equips your stack for evolving data and AI use cases, including copilots like Snowflake Cortex Analyst. [Metadata lakehouse](https://atlan.com/metadata-lakehouse/)

## What Snowflake customers achieve with Horizon data catalog and Atlan

Several organizations have integrated Atlan and Snowflake to transform their data operations. The page shows a carousel of Re:Govern sessions; watch them at the [Re:Govern watch center](https://atlan.com/regovern-watch-center/).

**North - Governance built for scale:** $1.4M/yr savings; 700% increase in tagged assets; 200% increase in Sigma adoption. "After partnering with Atlan, it took probably a couple of hours before we were integrated with Snowflake and Sigma, connecting to over 225,000 assets. Atlan started getting us this immediate value through data discovery. For us, Atlan became Google for Data." - Daniel Dowdy, Vice President, Data Analytics and Governance, North.

## FAQs about Atlan + Snowflake Horizon data catalog

**What is the primary difference between Snowflake Horizon data catalog and Atlan?**
Horizon is a technical, platform-native catalog designed to manage metadata within the Snowflake ecosystem. Atlan is a universal, business-user-friendly enterprise data catalog that acts as a governance and collaboration layer across the entire data stack, including Snowflake, Databricks, and various BI tools.

**Does Atlan replace Snowflake Horizon data catalog?**
No. Horizon remains your governance authority in Snowflake. Atlan complements it with cross-system discovery, lineage, and policy workflows so people outside Snowflake can still find and trust data.

**Can I get end-to-end lineage with the Snowflake Horizon data catalog alone?**
Horizon provides lineage within a single Snowflake workspace, but its lineage for external or federated sources and across multiple Snowflake workspaces is limited. Atlan provides end-to-end, column-level lineage across all your systems.

**How does governance work between Atlan and Snowflake Horizon data catalog?**
Bi-directional tag sync. Tags and policies flow both ways, enabling automated masking and consistent enforcement.

**How do Atlan and Snowflake Horizon data catalog integrate without creating conflicts?**
Atlan and Snowflake maintain a strategic partnership with native bi-directional tag synchronization. Policies defined in Atlan propagate to Horizon for technical enforcement, while Horizon's metadata enriches Atlan's business context.

**How does this affect our existing Snowflake investment?**
It extends Horizon's value across the broader ecosystem. Horizon continues optimizing Snowflake governance while Atlan adds cross-system capabilities and business user adoption Horizon wasn't architected to provide.

**What's the implementation complexity and timeline?**
A phased approach that preserves existing Horizon workflows. Organizations typically get immediate value through expanded discovery and business access, with full governance integration within 90-180 days depending on ecosystem complexity.

**Does Atlan support Snowflake Open Semantic Interchange?**
Yes. Atlan is a launch partner for Snowflake Open Semantic Interchange and extends semantic context across platforms and tools.

**Does Atlan support Snowflake Intelligence?**
Yes. Atlan is an official launch partner for Snowflake Intelligence and provides the metadata foundation and lineage needed to operationalize AI agents and intelligence-driven workflows across your stack.
