Snowflake access comparison
Snowflake Data Sharing vs customer portal
Choose Snowflake Secure Data Sharing when a capable data consumer wants governed read-only data in Snowflake. Choose a customer portal when people need a branded experience, application identity, explanation and workflow.
The direct verdict
Use Secure Data Sharing for customers that already work with Snowflake and want read-only data they can query in a data environment. Use a customer portal for account managers, operational teams and other people who need a clear interface, selected information, documents, support or a next action.
Do not build a portal merely to reproduce SQL access, and do not give business users a data-sharing workflow when they need a customer service. A hybrid can serve both audiences from the same governed data model.
01
Compare the two delivery models
| Decision factor | Snowflake Secure Data Sharing | Customer portal |
|---|---|---|
| Primary user | Data engineer, analyst or technical data consumer | Customer, partner or operational business user |
| Interface | Snowflake account and data tools | Purpose-built web or mobile experience |
| Consumer account | Snowflake account or provider-managed reader account | Application account and organisation membership |
| Data access | Read-only shared database objects | Approved application responses, reports, files and search |
| Brand and guidance | Data-platform experience | Branded navigation, definitions and support |
| Customer workflow | Not provided by the share | Requests, evidence, approvals, notifications and status |
| Query flexibility | High for capable consumers within shared objects and privileges | Bounded to supported customer tasks |
| Onboarding | Share, account, roles and data-consumer enablement | Invitation, organisation membership, roles and customer support |
| Operations | Sharing, account, warehouse use and data contract | Application availability, identity, access, workload and workflow |

Choose a customer portal for a guided service
A portal is the better fit when the customer should not need data-platform knowledge. It can combine Snowflake-backed reporting with live operational information, documents and customer actions.
- Use application identity and delegated customer administration.
- Present only the records, measures and filters needed for the task.
- Explain freshness, definitions and material limitations close to the result.
- Generate bounded exports without exposing warehouse credentials.
- Attach questions, evidence and approvals to the relevant record or reporting period.
- Route actions to the system that owns the operational process.
The architecture guide explains how to build a customer portal on Snowflake without making the warehouse the application.
04
Use both when one customer has distinct audiences
The shared model can establish approved definitions and history, while each channel applies its own contract and controls. Keep identity, entitlements and usage separate. A customer's access to a portal does not automatically grant a share, and a share does not automatically grant portal workflow permissions.
Publish changes deliberately. A renamed field may affect a customer's data pipeline, while revised portal copy may affect business users. Each channel needs its own versioning, support and adoption plan.
05
Use this decision checklist
- Identify whether the primary consumer is a person, a data team or software.
- Define whether they need exploration, a guided task, machine integration or several of these.
- Confirm whether the customer uses Snowflake and can operate a data contract.
- List any workflow, documents, support or operational actions around the data.
- Define customer scope, field policy, freshness and expected volume.
- Compare onboarding and ongoing support, not only initial implementation.
- Use separate channels only where each has a clear audience and owner.

Questions
Frequently asked questions
Is Snowflake Data Sharing a customer portal?
No. Secure Data Sharing provides read-only access to selected Snowflake objects for data consumption. A customer portal is an application for human identity, navigation, explanation, files, support and operational workflow.
Does Secure Data Sharing copy the data?
Snowflake states that Secure Data Sharing makes selected objects available without copying or transferring the shared data. Consumers query the read-only shared objects using their own account or a provider-managed reader account.
What if the customer does not use Snowflake?
Use a customer portal for human access, an API or export for machine access, or assess a reader account for a capable data consumer. Snowflake also documents Open Data Sharing as a Preview feature, so check its current status before relying on it.
Can a business use both Data Sharing and a portal?
Yes. A data team can consume governed shared objects while operational users use a portal built around the same approved definitions. Treat them as two channels with distinct identity, workload and support controls.
Which option supports customer actions?
A portal supports actions such as questions, uploads, approvals and requests through application workflows. Secure Data Sharing is a read-only data-consumption mechanism and does not by itself implement those workflows.
