AI Data Access Controls for Sensitive Databases and Data Warehouses
Control what AI systems, agents, and applications can see when they touch sensitive data. Ubiq protects the values inside your databases, warehouses, and AI workflows, then evaluates the requesting identity, context, and policy at runtime to return cleartext, masked, tokenized, or encrypted data. Support AI without broadly exposing regulated or sensitive data.

CMMC 2.0 Level 1What are AI data access controls?
AI data access controls govern what sensitive data an AI system, agent, application, or user can see when it reaches enterprise databases and warehouses. Database and warehouse controls can restrict access at the table, row, column, or view level, but those controls are often tied to a specific platform or access path. Ubiq complements them by protecting sensitive values and applying identity-governed policy across applications, APIs, databases, warehouses, and AI workflows.
AI uses direct and indirect access paths
AI may reach sensitive data directly through database or warehouse connections, or indirectly through applications, APIs, service accounts, tools, MCP servers, retrieval services, notebooks, BI systems, and automation.
Table and dataset access are too coarse
A single table, view, dataset, or warehouse query can hold both low-risk operational fields and highly sensitive values such as PII, PHI, financial data, credentials, identifiers, regulated records, or data subject to residency requirements.
Identity needs to follow the request
The same sensitive data should return the configured representation for the requesting identity. Ubiq evaluates the requesting identity, context, and policy at runtime.
Same data. Same table or dataset. Different runtime outcomes based on identity and policy.
Database and warehouse controls govern access. Ubiq governs the sensitive value.
Database and warehouse controls can restrict access at the table, row, column, view, and query-path levels. Those controls are often tied to a specific platform or access path. Ubiq complements them by protecting sensitive values and returning the configured runtime outcome for each requesting identity.
Example
Access decision
Returned to AI workflow(in cleartext)
mariac@acme.com
555-12-1234
$48,230
The workflow can now expose those values through prompts, responses, logs, embeddings, vector stores, exports, BI tools, notebooks, and downstream applications.
Common challenges
- AI workflows inherit broad application, warehouse, or service-account permissions
- Table or dataset access exposes more sensitive fields than the workflow needs
- Sensitive values are returned in cleartext once access is allowed
- Prompts, logs, embeddings, vector stores, and exports create new exposure paths
- Hard to tell the user, app, agent, API, and service account apart behind a request
Example
Protected at rest(encrypted or tokenized)
Runtime outcome by identity
- Fraud investigator555-12-1234
- Support copilot•••-••-1234
- Analytics notebookTOK-9F4B-D108
- AI agentTOK-4T8V-2031
The underlying value stays protected while the requesting identity receives the configured representation.
Key benefits
- Protect sensitive values underneath database and warehouse access
- Evaluate identity, context, and policy before returning data
- Enforce least privilege at the data value level, not just the table
- Support cleartext, masked, tokenized, or encrypted outcomes
What traditional data access controls do not solve
Database and warehouse permissions, IAM roles, row-level security, table grants, application access controls, and BI permissions all matter. But they were not designed for AI workflows that retrieve, summarize, transform, store, and redistribute sensitive data across multiple systems.
Table and dataset access do not equal field-level safety
An AI workflow may need a table, view, dataset, or query result for a valid reason, but only a subset of fields may be appropriate. Table-level access can expose sensitive values the workflow does not need.
Service accounts can become overpowered
Many AI workflows access data through application identities, warehouse roles, API keys, or service accounts. Those accounts often carry broader permissions than the actual user, agent, or workflow should inherit.
AI access can be indirect
The data platform may see an application, service account, tool call, or API request, while the business request originated from a human, agent, copilot, workflow, or automation path. It is hard to decide based on the real requester.
Data residency becomes harder after retrieval
Once data subject to residency requirements is returned in cleartext, it can appear in prompts, logs, summaries, caches, vector stores, exports, tickets, BI extracts, and notebooks. Controls need to apply before the value is exposed.
Native masking often protects only one path
Masking in a database, warehouse, view, or application may work for one access pattern, but AI workflows can reach the same data through APIs, services, notebooks, pipelines, BI tools, MCP servers, tool layers, and agents.
Object access does not always control value exposure
Many controls decide whether the requester can reach an object or data path. Ubiq complements those controls by governing which protected or unprotected representation of each sensitive value the requester receives.
Ubiq reduces that blast radius by protecting sensitive values and applying identity-governed policy at runtime across applications, APIs, SDKs, SQL UDFs, databases, warehouses, data services, and AI workflows.
Access paths
AI data access can happen through many paths
AI may reach sensitive data directly through database or warehouse connections, or indirectly through applications, APIs, service accounts, tools, MCP servers, retrieval services, notebooks, BI systems, and automation.
Direct data access
Application-mediated
Agent and tool-mediated
Analytics and BI
Retrieval and RAG
The risk is not the specific path. The risk is that AI creates new ways for sensitive data to be accessed, transformed, summarized, logged, embedded, and shared. Ubiq enforces policy at the data value level so the runtime outcome stays controlled wherever the access path begins.
How Ubiq works
Same sensitive data. Different identities. Different runtime outcomes.
The same protected customer record can return different configured representations. Ubiq evaluates the requesting identity, context, and policy at runtime, then returns cleartext, masked, tokenized, or encrypted data.

Where teams use AI data access controls
Wherever AI systems, agents, applications, and service accounts touch sensitive data, teams use identity-governed controls to decide what each workflow can actually see.
Enterprise copilots and AI assistants
Let copilots answer business questions while limiting which sensitive fields can be returned, summarized, or exposed in responses.
RAG and retrieval workflows
Retrieve relevant enterprise records while keeping sensitive source fields masked, tokenized, or encrypted unless policy allows cleartext.
Databases and data warehouses
Enforce field-level and column-level outcomes at runtime, so different users, apps, service accounts, and AI workflows hitting the same table receive different versions.
Data residency and regional access
Keep region-bound values protected, then apply the approved identity, context, and policy model before returning a configured representation.
AI agents and automation
Govern what agents can reveal when they query databases, call APIs, trigger actions, use tools, or move data between systems.
Analytics, BI, and notebooks
Let analysts and AI-enabled analytics tools work with production-like data while sensitive values stay masked, tokenized, or otherwise protected.
Insider threat and overprivileged access
Reduce the blast radius of broad DBA, admin, developer, warehouse-admin, service-account, or operator access by controlling what each identity can actually reveal.
Lower environments and model development
Support development, testing, evaluation, and model workflows with realistic protected data instead of unrestricted production cleartext.
Ubiq is built to fit your environment
Ubiq provides a SaaS control plane while protection and reveal operations execute through integrations inside your environment. Sensitive data does not need to be sent to Ubiq for protection, tokenization, masking, or runtime reveal.
Works with your identity provider
Reuse your existing IAM and identity provider integrations. Ubiq evaluates the requesting identity, context, and policy at runtime before returning the configured data representation.
Database and warehouse integration
Protect and reveal values through SQL UDFs and native database and data warehouse integration patterns.
SDKs and APIs
Add protection directly into applications, services, agents, and workflows through SDKs and APIs.
Application and API patterns
Integrate at applications, services, and API gateways without rearchitecting how they reach sensitive data.
AI workflow and tool integration
Apply controls where sensitive data is accessed, transformed, or returned: application backends, APIs, agents, tool layers, retrieval services, and data services.
No agents or proxies in the data path
Ubiq does not require a proxy between applications and databases or warehouses, so there is no new bottleneck to route sensitive traffic through.
No database schema changes where applicable
Protect and reveal values without changing existing table schemas where the integration pattern allows.
Customer-managed keys
Use customer-controlled key management, including HSM or KMS options, so key control stays with your team.
AI data access control vs database and warehouse access control
Database and warehouse access control and AI data access control are complementary. One controls access to systems, tables, roles, views, datasets, and query paths. The other controls what sensitive values are actually revealed once a workflow reaches the data.
Database and warehouse access control
Determines whether a user, role, application, or service account can access an object such as a table, view, schema, stored procedure, dataset, query, or warehouse resource.
- Controls access to database and warehouse objects
- Based on users, roles, grants, groups, service accounts, and IAM
- Useful for table, row, schema, view, and query-level authorization
- May still return sensitive values in cleartext when access is allowed
AI data access control
Determines what version of each sensitive value an AI workflow, agent, application, service account, API, or user should receive at runtime.
- Controls exposure of sensitive data values
- Evaluates the requesting identity, context, and policy
- Supports cleartext, masked, tokenized, or encrypted outcomes
- Reduces exposure across prompts, logs, agents, vector stores, BI tools, and notebooks
With Ubiq, database, warehouse, and identity-governed data protection work together. The data platform can decide whether a workflow reaches the table, view, or dataset, while Ubiq decides what protected or unprotected version of each value the requester receives. It is the same principle behind dynamic data masking and vaultless tokenization, applied to AI-driven workflows, agents, service accounts, APIs, tool layers, warehouses, and pipelines.Same data. Same record. Different runtime outcomes based on identity and policy.
Frequently asked questions
What are AI data access controls?
AI data access controls determine what sensitive data an AI system, agent, application, service account, API, or user can access and reveal when interacting with enterprise data. Instead of only deciding whether a workflow can access a table, warehouse, dataset, or system, AI data access controls determine what version of each sensitive value should be returned: cleartext, masked, tokenized, or encrypted.
Why do AI workflows create new data security risk?
AI workflows can access data directly or indirectly through database connections, applications, agents, APIs, service accounts, notebooks, BI tools, retrieval systems, MCP servers, or tool layers. That makes it hard to know whose permissions should apply and whether the workflow should receive cleartext, masked, tokenized, or encrypted values. The same sensitive data can be exposed through prompts, responses, logs, embeddings, vector stores, and downstream systems.
Why is table-level or dataset-level access not enough for AI?
A table, view, or dataset can contain many types of data with different sensitivity levels. An AI workflow may need the dataset to answer a business question, but it may not need every sensitive field in cleartext. Field-level and value-level controls reduce overexposure by returning only the version of each value that policy allows.
Can Ubiq work with Okta for AI data access control?
Ubiq integrates with existing IAM and identity providers, including Okta. Ubiq evaluates the requesting identity, context, and policy at runtime, then returns the configured cleartext, masked, tokenized, or encrypted representation.
Can Ubiq control access by application, service account, API, or AI agent?
Yes. Applications, service accounts, APIs, and AI agents can act as requesting identities. Ubiq evaluates the requesting identity, context, and policy at runtime, then returns the configured cleartext, masked, tokenized, or encrypted representation.
Does Ubiq replace database or warehouse permissions?
No. Ubiq complements database and warehouse permissions. Database and warehouse controls determine whether a requester can access a table, view, dataset, or query path. Ubiq governs what sensitive values are revealed when that access occurs.
How does Ubiq help with data residency?
Ubiq keeps sensitive values protected and evaluates the requesting identity, context, and policy at runtime before returning the configured representation. This can reduce unnecessary cleartext exposure as data moves through applications, AI systems, warehouses, and downstream tools.
Can Ubiq protect data used in RAG, prompts, and vector stores?
Yes. Ubiq can protect sensitive source fields before they enter retrieval, prompt, evaluation, or vector workflows and can govern when protected values are revealed through integrated applications, APIs, databases, and data services. Vector-search use cases require coordinated protection of source data and vector representations, including corresponding transformation of query vectors, as described on Ubiq's RAG security page. Teams must still control how downstream AI components handle any cleartext that policy permits them to receive.
What runtime outcomes can Ubiq return?
Ubiq evaluates the requesting identity, context, and policy at runtime, then returns a configured cleartext, masked, tokenized, or encrypted representation. This applies least-privilege principles at the data-value level, not only at the system or table level.
