Report Overview

AI is reshaping how data is collected, processed, and applied. But most governance frameworks weren’t designed for AI’s speed, complexity, or scale. Sensitive data flows through training pipelines, third-party models run without oversight, and shadow tools operate beyond the reach of IT and security teams.

Legacy systems can’t provide the visibility or control today’s environments demand. Many teams are still using manual reviews, static policies, and disconnected tools to manage risk across AI workflows. That leaves gaps, especially around model behavior, data usage, and regulatory compliance.

The urgency is rising. 94% of practitioners list data protection as their top AI governance priority. More than three-quarters say traditional controls can’t keep up. As investment in AI increases, so does the need for policy automation, real-time monitoring, and model-level accountability.

The 2025 Link Index for AI Data Governance gives teams a clear view of where the market stands and which vendors are solving real-world problems. We evaluated 68 platforms based on the criteria that matter most: accuracy, data quality, compliance alignment, and operational control. From that review, 24 vendors stood out for their ability to deliver complete, scalable governance across the AI lifecycle.

Key Takeways:

AI governance is becoming a top-line priority: As AI touches more critical workflows, organizations need stronger controls across data pipelines, models, and third-party systems.
Legacy governance tools are falling short: Manual reviews and static policies can't provide the visibility, precision, or speed required to manage modern AI risk.
Buyers are focused on trust, transparency, and compliance:Practitioners are prioritizing accuracy, data quality, and policy enforcement to meet regulatory demands and reduce exposure.
The leaders are solving for the full lifecycle This Index spotlights 24 vendors delivering policy automation, model oversight, and scalable governance from development through deployment.

Methodology
The Link Index offers a detailed analysis and ranking of leading vendors for specific use cases, leveraging robust data and insights from Liminal’s market and competitive intelligence platform, Link. Liminal’s research team invites solution providers to participate in a company survey and analyst briefing. It uses a proprietary framework to assess and rank product capabilities based on their relevance to market needs. Liminal’s Digital Identity Landscape taxonomy and ontology are central to the Link Index, which precisely evaluates vendor solutions by buyer demand, product capability, and market presence. Liminal conducts a rigorous survey among buyers in the vendor selection process to identify the most in-demand product capabilities and the most valued product components. Market presence criteria included buyer satisfaction, market penetration, and brand recognition. The Link Index was designed to be used to inform go-to-market strategy and execution and provide guidance for solution buyers, specifically:
- Executives in corporate strategy
- Leaders of go-to-market execution
- Practitioners of solution implementation
