Published July 25, 2025

As professionals in the data space, we’ve seen countless organizations struggle with data access, particularly as they grow and scale. From endless ticketing systems to manual approvals that bottleneck innovation, the struggle to balance data utility with robust security has been a persistent challenge. And as AI adoption accelerates, things will only become more complex.

But having worked with these major organizations for many years, we’ve also seen what works to alleviate burdensome processes and strike the elusive utility-security balance – which brings us to the current moment. The future is here, and it’s powered by intelligent automation and streamlined workflows within Immuta’s data provisioning platform.

In this blog, we’ll look at why it’s time to let traditional approaches go, and how integrating automated rules with intelligent exceptions is key to unlocking more value from data while minimizing risks.

The old way: A recipe for frustration and risk

Let’s face it – the traditional approach to data access has been, to put it mildly, inefficient. It often looks something like this:

  • Manual ticketing overload: Every data request, no matter how simple, often starts with a ticket. These pile up, creating backlogs for data teams and leaving data consumers waiting for extended periods for the insights they need.
  • Version control nightmares: To accommodate different access levels, organizations resort to creating multiple, slightly varied versions of the same dataset. This leads to data duplication, inconsistencies, and a monumental effort to keep everything in sync.
  • Reactive and burdensome approvals: Approvals are often a manual, ad hoc process. Data stewards and governors are constantly chasing down context, trying to understand the “why” behind each request, and making decisions in a vacuum. The process is slow and error-prone, making audits difficult.
  • Rigid, role-based access control (RBAC): RBAC’s rigidity makes it poorly suited for the dynamic nature of modern data stacks. A user’s role might grant broad access, even when only a subset of data is truly needed for a specific task. Or, it might be too restrictive, forcing multiple, complex requests for nuanced access. This often leads to overprovisioning or underprovisioning data access.
  • Lack of visibility and auditability: When access decisions are scattered across various systems and managed via manual processes, gaining a clear view of access details and user intent is a near-impossible feat, making compliance a constant headache.

This outdated approach isn’t just inefficient; it’s a significant risk vector, increasing the chances of data breaches, non-compliance, and ultimately, hindering your organization’s ability to extract timely value from its data.

As new technologies emerge and AI becomes more ubiquitous, these risks will only become more acute – and so will the consequences of not being able to deliver data to the right people at the right time.

The solution: Automated rules, intelligent exceptions

The core of the data steward’s strategy involves a powerful combination of automated rules and the flexibility to implement streamlined, fine-grained exceptions.

Automated rules serve as the foundational layer of data access control. They enable data stewards to define broad policies that automatically govern access to large segments of data based on predefined criteria such as user roles, data sensitivity levels, and compliance requirements. This automation significantly reduces the manual effort involved in managing access requests for common scenarios, ensuring consistency and accelerating the provisioning of data to authorized users.

However, the complexity of real-world data usage often necessitates deviations from these general rules. This is where the option for streamlined, fine-grained exceptions becomes critical. These exceptions allow data stewards to grant specific, controlled access to datasets for particular users or use cases that don’t fit neatly within the established automated rules. This might include granting temporary access for a specific project, providing access to a subset of data for a particular analysis, or accommodating unique regulatory requirements. The key is that these exceptions are not ad hoc, but rather carefully managed and auditable, ensuring that even deviations from the norm are risk-mitigated.

At Immuta, we’ve reimagined data access from the ground up, focusing on automation, intelligent governance, and empowering both data consumers and data owners. This makes our approach fundamentally different – and able to adapt to the changing nature of data provisioning in the AI era.

1. Automating access rules with attribute-based access control (ABAC)

Instead of relying on rigid roles, Immuta leverages attribute-based access control (ABAC). This means access is granted or denied based on a dynamic set of attributes, which can be associated with the user, the data itself, or even the environment. For example, policies can combine a user’s department or security clearance, the data’s sensitivity level, and the time of day to make a decision.

How it works: Data owners and governors define policies in natural language using these attributes. A policy might state: “Marketing analysts in North America can view customer demographics data, but only masked email addresses and anonymized financial information.”

The advantage: This eliminates the need for hundreds or thousands of static policies. A single, dynamic ABAC policy can apply across your entire data estate, automatically adapting as user attributes or data classifications change. When new data is ingested or a user’s role changes, access is instantly and consistently enforced, without manual intervention or new tickets. This drastically reduces policy bloat and maintenance burden – in fact, studies show ABAC can reduce policy changes by 93x compared to traditional RBAC.

2. Managing exceptions through provisioning workflows

We understand that even with the most robust automated rules, exceptions are inevitable. For instance, if a finance user needs access to a marketing dataset for a specific project, they may request an exception to the enforced policy. This would set off a one-off workflow in which a data steward tracks down the details of the request and determines the appropriate level and/or duration of access to grant. Clearly, this is a time-consuming distraction from typical responsibilities that can cause ticketing backlogs to grow even more.

This is where Immuta’s data provisioning capabilities truly shine, transforming exception management from a painful chore into a streamlined, auditable process. Immuta’s processes simplify exception management by:

  • Empowering data consumers: Users can easily discover available data products and request access to them within the Immuta Platform. If a specific data element is masked by a policy and they require full access for a legitimate business need, they don’t have to start a new, burdensome ticket. Instead, they can submit a masking exception request directly in Immuta. This request is highly specific, showing exactly which parts of the dataset are currently masked and why, and prompting the user for a clear business justification.
  • Streamlining approval workflows: The request is then routed to the appropriate data owner or steward based on predefined workflows. They receive all the necessary context: the requested data, the current masking policy, the business justification, and even sample data with the masking applied. This eliminates the back-and-forth typically associated with approvals.
  • Delivering AI-powered Review Assist: To further accelerate and improve decision-making, Immuta’s Review Assist feature leverages AI to classify access requests as low, medium, or high risk based on historical access patterns, user roles, and data sensitivity. It even provides an AI-generated rationale, helping approvers quickly assess and approve low-risk requests in bulk, while focusing their attention on higher-risk exceptions.
  • Granting granular, temporary access: Approvers can grant highly granular exceptions – not just full access to an entire dataset, but specific column access or even temporary access for a defined period. This ensures that users get only the precise data they need for the time required, significantly reducing risk.
  • Serving as a single source of truth: Immuta maintains a single version of the data product. Exception handling is managed dynamically by policy, eliminating the need to create duplicated datasets for different access levels. This simplifies data publishing for data product owners and ensures consistency for consumers.
  • Enabling full auditability: Every request, approval, and denial, along with the reasoning and policy changes, is meticulously logged in Immuta’s unified audit log. This provides an irrefutable record for compliance and internal governance.

How to manage exceptions with AI

Further enhancing the efficiency and intelligence of this system are Immuta’s AI-generated recommendations. These recommendations play a pivotal role in minimizing the proliferation of exceptions over time. By analyzing patterns in data approval processes and consumer profiles, Immuta’s AI recommendations can identify recurring scenarios that currently require manual exceptions. Based on these insights, the AI can then recommend the creation of new automated rules.

For instance, if a specific department consistently requests access to a particular data subset for a recurring analytical task, Immuta AI might suggest a new automated rule that grants this access without requiring individual exceptions. This proactive approach not only reduces the number of exceptions, but also continuously refines and optimizes the automated access control framework, making it more robust and adaptable.

In essence, data stewards leverage a sophisticated ecosystem that balances broad automation with precise exception control. This approach ensures that data users can access the information they need quickly and efficiently, while simultaneously guaranteeing that sensitive data remains protected and compliant with all relevant regulations. Immuta AI’s continuous learning capabilities further enhance this process, leading to a more efficient, secure, and adaptable data governance strategy.
