TLDR: Microsoft Purview is the right call for Microsoft-stack enterprises that need unified compliance and security governance. Collibra is the established choice for large organizations with complex, policy-heavy governance requirements. Alation wins on data discovery and business-user adoption. The right answer depends on your existing tech stack , governance maturity, and whether your primary driver is compliance enforcement, catalog usability, or organizational adoption.
Key Takeaways Microsoft Purview integrates natively with Azure, Microsoft Fabric, Power BI , and Microsoft 365 — it’s the strongest option if you’re already in the Microsoft ecosystem and need compliance, DLP, and data cataloging in one place. Collibra offers the deepest enterprise governance workflows, but base pricing starts around $170,000/year and implementation typically takes 6+ months. ROI tends to show up at the 25-month mark, according to G2 review data. Alation leads on data discovery and business-user adoption. It deploys faster and is easier to administer, but compliance depth for regulated industries lags Collibra and Purview. All three platforms are adding AI governance capabilities — relevant as over 1,000 AI-related policies are now active across 69 countries. For organizations running Microsoft infrastructure, Purview is often not just the most convenient choice — it’s the most cost-effective one, especially when factored into existing Microsoft licensing . The Decision Most Data Teams Get Wrong Maria was eight months into a Collibra implementation when she finally said it out loud in a steering committee meeting: “We built a governance platform that nobody uses.”
The tools were configured. The workflows were live. The business glossary had over 2,000 terms. And yet when Maria walked the floor of her financial services firm, analysts were still sharing Excel files over email and running the same data quality checks they’d been doing manually for years. The platform had been implemented. It just hadn’t been adopted.
What went wrong? Maria’s team evaluated Collibra, Purview, and Alation the way most enterprise teams do: by feature matrix and analyst report. Collibra won on governance depth and compliance workflow sophistication. The implementation team was technically competent. The executive sponsor was committed. And still, when the rubber hit the road, the platform didn’t fit the way the business actually worked.
Maria’s story isn’t unusual. Adoption failure is the most common outcome in enterprise data governance implementations. Not technical failure. The platform works fine. People just don’t use it.
The question that matters in a platform evaluation isn’t “which tool has the most governance features?” It’s “which tool will our organization actually adopt, and does it fit where our data already lives?” Those are different questions. And most comparison articles don’t help you answer either of them.
Before getting into the feature-by-feature breakdown, it helps to understand what each tool was designed for.
Microsoft Purview was formed by merging Azure Purview (data cataloging) with the Microsoft 365 Compliance Center (DLP, information protection) into a single platform. Its primary use case is enterprises that need a governance and compliance layer across the Microsoft ecosystem: Fabric, OneLake, Azure Synapse , Power BI, Teams, SharePoint, and increasingly Copilot. It’s not the deepest governance platform, but it has the broadest native coverage for Microsoft workloads, and for organizations already paying Microsoft enterprise licensing, the marginal cost is often low.
Collibra was purpose-built for enterprise data governance from the start. It launched in 2008 with a focus on data stewardship , business glossaries, and policy management. The organizational and process side of governance, not just cataloging. Large regulated enterprises in financial services, healthcare, and pharma have historically been Collibra’s core market. For financial services teams specifically, Kanerika has a dedicated guide on data governance in banking that covers the regulatory pressure driving these decisions. It handles complex governance at scale better than most alternatives, but that depth comes with implementation complexity and cost.
Alation approached governance from the data catalog angle. It pioneered behavioral analysis: understanding how people actually use data, not just documenting what exists. The result is a platform business users actually open without being told to. Over 40% of Fortune 100 companies use it, according to Alation’s own published customer data . Alation has added governance and lineage capabilities over the years, but discovery and cultural adoption remain its core strengths.
If you’ve already narrowed your comparison to two tools, Kanerika’s Purview vs Collibra guide covers that comparison in depth. For a broader look at who else operates in this market, the data governance companies guide covers the competitive landscape. This article adds Alation to the picture and provides the fuller framework for teams still evaluating all three.
Feature Comparison: What Matters at the Enterprise Level Data Cataloging and Discovery All three platforms offer automated metadata discovery, business glossaries, and data lineage . But how they work differs significantly.
Alation’s behavioral analysis engine is the most distinctive feature in this category. Rather than just cataloging what data exists, it tracks how data is actually searched and queried across the organization. This makes it better at surfacing the most trusted datasets, and at helping business analysts find what they need without relying on technical documentation — which is one of the core goals of data democratization . Deployment can be measured in days for targeted use cases. Its 120+ pre-built connectors cover AWS, Snowflake, Salesforce, and Databricks without custom engineering.
Purview’s cataloging is automated and scales across the Microsoft ecosystem with minimal manual work. It connects to Azure storage, SQL databases, Power BI, SharePoint, Synapse, and Fabric natively. For non-Microsoft sources (AWS, GCP, Salesforce, Snowflake), connectivity exists but often requires additional configuration. For organizations with a predominantly Microsoft data estate, Purview’s coverage is difficult to match at the price point. Kanerika’s Microsoft Purview consulting practice covers this in detail, including how to extend Purview’s scanning to multi-cloud environments.
Collibra’s catalog is comprehensive but heavier to configure. It requires significant upfront setup — taxonomy design, governance workflow configuration, and metadata enrichment — before it delivers full value. Once configured, it’s highly flexible and customizable. Organizations should plan for a 6-month implementation minimum and a dedicated admin team to keep the system current.
Data Lineage Column-level lineage is where the platforms diverge most clearly.
Collibra has the strongest automated lineage capabilities, mapping data flows across ETL pipelines, BI tools , and databases with high coverage. Lineage is a separate module with its own licensing, which adds cost, but it delivers depth that most alternatives can’t match. This is why Collibra is frequently the default in financial services and life sciences where proving data provenance is a regulatory requirement.
Purview provides end-to-end lineage across Azure services out of the box. For Azure-native environments, this works reliably and with minimal setup. Cross-platform lineage — tracing data from an on-premises database through Azure Data Factory into Power BI — is supported but requires careful configuration. For organizations running enterprise data governance with Microsoft Fabric , Purview’s lineage capabilities are often sufficient without additional tooling.
Alation offers lineage capabilities and integrates with over 120 data sources. Column-level lineage has historically been a paid add-on, which users have flagged as a friction point given how central lineage is to compliance workflows. For teams where lineage is primarily about understanding data flows rather than regulatory audit trails, Alation’s approach is practical.
Data Governance and Policy Management This is where Collibra’s depth is most evident. Its governance workflows cover the full lifecycle: ownership assignment, stewardship workflows, policy creation, approval processes, and ongoing compliance tracking. It supports federated governance where each business unit manages its own data domain while adhering to organization-wide standards. Workflow automation is sophisticated — approval chains, escalation paths, and remediation workflows that would require custom development elsewhere.
Purview’s governance capability is strong within the Microsoft ecosystem. Sensitivity labels, DLP policies, access controls, and compliance frameworks (GDPR, HIPAA, PCI-DSS) are built in and integrate with Microsoft Entra ID for identity management. Where Purview is weaker is in cross-system governance workflow automation — if governance needs to extend deeply into non-Microsoft systems, policy enforcement starts to show gaps. Kanerika’s KANComply solution addresses this by mapping Purview policies to specific regulatory requirements and maintaining ongoing compliance reporting across hybrid environments.
Alation’s governance features have matured through continuous development but aren’t at Collibra’s depth for policy workflow management. For organizations at an earlier data governance maturity stage, Alation’s approach is often more practical — governance that gets adopted is more valuable than governance that gets bypassed.
Compliance and Regulatory Coverage In regulated industries, this dimension often determines the decision.
Purview covers GDPR, HIPAA, PCI-DSS, ISO 27001, SOC 2, and a range of industry-specific frameworks through built-in compliance templates. Its integration with Microsoft 365 means that data classification, information protection, and compliance reporting connect across email, documents, cloud storage , and databases. For organizations running Microsoft security stacks (Defender, Sentinel, Entra), Purview plugs directly into that infrastructure. This is particularly relevant in industries like financial services and healthcare, where data governance challenges often center on proving compliance across fragmented data environments.
Collibra has the deepest audit trail and policy enforcement capabilities, and it’s the preferred platform in industries where compliance is deeply organizational — where proving who made data decisions, when, and why matters as much as the decision itself. Financial services, life sciences, and public sector organizations that have mature governance programs frequently choose Collibra for this reason.
Alation supports compliance workflows but is generally not the first choice where audit trail depth is the primary requirement.

The gap between ‘time to first value’ across these platforms is significant and rarely discussed. Organizations that underestimate implementation effort, particularly with Collibra, often end up with a governance platform that’s technically live but organizationally stalled. That’s Maria’s story from the intro — and it plays out more often than vendor case studies suggest. Kanerika’s guide on data governance vs data management covers why organizational readiness matters as much as the tool you choose.
The Pricing Reality Data governance platform costs are difficult to compare cleanly because licensing structures, module pricing, and implementation costs vary significantly.
Microsoft Purview is often partly or fully covered by existing Microsoft enterprise agreements. Organizations already paying for M365 E5 or Azure subscriptions may have Purview capabilities included at marginal cost. Standalone pricing is consumption-based for some features and per-user for others. For Microsoft-aligned enterprises, this frequently makes Purview the most cost-effective option in this comparison — not because it’s the cheapest standalone tool, but because the incremental cost within an existing Microsoft investment is low.
Collibra base subscription pricing starts at approximately $170,000 per year. That’s the floor. Data lineage and data quality are separate modules with their own licensing. Implementation typically requires 6+ months and professional services support, meaning the total cost of ownership across the first two years substantially exceeds the base subscription. According to G2 review data, ROI is typically realized at the 25-month mark. Organizations that choose Collibra need to budget for both the platform and the organizational program around it.
Alation is in a similar licensing range to Collibra, but implementation is generally faster and less expensive. Long-term agreements offer meaningful discounts. TCO tends to be lower than Collibra for most implementations, particularly where governance maturity is still developing and adoption is the primary challenge.
A useful framing from data governance tools research: the real cost comparison isn’t just licensing — it’s how quickly each platform starts delivering measurable governance value against what it costs to get there.
What Independent Analysts Say If you’re making this call at a large enterprise, analyst reports will come up in your internal justification process. Here’s where the three platforms actually land.
Both Collibra and Alation were named Leaders in the Forrester Wave: Data Governance Solutions, Q3 2025
Alation earned its own Leader placement in the Forrester governance report , with research noting a market shift toward agentic AI and automated governance. Forrester called out Alation’s strength in building governance that business users actually engage with — not just governance that exists on paper.
Microsoft Purview sits in a different part of the analyst landscape. It appears in Gartner’s evaluations of data and analytics governance, but its primary recognition comes within Microsoft’s broader security and compliance ecosystem. That reflects where Purview is genuinely strongest — as the governance layer for Microsoft-infrastructure organizations — rather than a weakness in the standalone data governance market.
The practical takeaway: if your procurement process needs a Forrester or Gartner citation, both Collibra and Alation can provide one. The Forrester Wave: Data Governance Solutions, Q3 2025 is the most current independent evaluation to reference internally. For Microsoft-aligned organizations, Purview’s case is better made through the lens of ecosystem integration and existing licensing economics.
What Real Users Actually Complain About Feature matrices tell you what platforms claim to do. Gartner Peer Insights reviews tell you what it’s actually like to live with them. The patterns across verified user reviews are worth understanding before you sign anything.
Collibra: The most consistent complaint centers on search — described by multiple Gartner reviewers as “weak and frustrating” and “not intuitive,” with users noting they’d raised the issue “for years without much success.” For a data catalog whose core job is discoverability, this is a significant gap. A second recurring pattern: assets aren’t searchable until they clear multi-stage approval workflows, meaning data consumers encounter empty results even when relevant data exists. Users also flag that business metadata enrichment still requires significant manual effort despite the platform’s technical sophistication, and that access management runs separately from standard data workflows — creating friction for onboarding new users. None of this disqualifies Collibra, but it does mean adoption depends heavily on dedicated administrators and a serious change management program.
Microsoft Purview: The most cited limitation on Gartner Peer Insights is catalog search behavior. Users describe partial term matching as limited and results as returning thousands of assets without meaningful prioritization — a notable irony for a product positioned as a data discovery platform . Users also observe that Purview’s investment appears more heavily weighted toward security and compliance features than catalog usability. For organizations needing governance depth outside the Microsoft ecosystem — custom metadata, sophisticated lineage across non-Azure sources, or complex stewardship workflows — friction appears quickly. The consistent praise covers setup speed, cost-efficiency for Microsoft environments, and Azure integration quality.
Alation: The primary complaint is that column-level lineage — one of the most important features for compliance workflows — has historically been a paid add-on rather than included by default. Users in regulated industries also note that sophisticated stewardship workflows and policy enforcement depth lag behind Collibra. That said, Alation holds a 4.6 rating on Gartner Peer Insights across 205 reviews, and users consistently describe deployment and administration as genuinely easier than the alternatives.
The common thread: these platforms deliver on their promises, but each has specific operational weaknesses that don’t appear in marketing materials. Knowing them before you start is the difference between a governance program that scales and one that stalls at adoption.
What Happens If You Choose Wrong Switching costs are rarely part of a vendor evaluation. They should be.
Switching data governance platforms is expensive — not primarily because of licensing, but because of the organizational investment built around the platform. Implement Collibra and you’re not just deploying software. You’re reconfiguring workflows, training data stewards, building taxonomy structures, writing business glossaries, and creating data quality rules. That organizational capital doesn’t transfer cleanly if you decide to move on.
The typical pattern: organizations that implement Collibra and later migrate generally lose 6–18 months of implementation work that can’t be cleanly ported. Business glossaries are partially transferable; workflow logic, custom configurations, and the governance processes people have internalized are not. Purview migrations within the Microsoft ecosystem are better supported — Azure Data Catalog to Purview migration comes with tooling. But moving from Purview to Collibra or Alation means rebuilding catalog structures from scratch.
Alation’s switching profile is different. Because its value is behavioral and discovery-oriented, the organizational capital built in Alation — trained users, established search habits, trusted datasets — lives more in culture than configuration. Organizations that move away from Alation typically lose catalog structure but retain a more data-literate workforce.
What does this mean practically? The governance maturity assessment you do before selecting a platform matters more than the feature comparison you do during it. If your organization isn’t ready for Collibra’s governance complexity, deploying it and then retreating is more expensive than starting with Alation and graduating up. Kanerika’s initial assessment process is specifically designed to catch this mismatch before implementation starts — checking not just technical fit, but whether your organization has the governance maturity to extract value from the platform you’re considering.
Can You Run Purview and Collibra Together? Some enterprises do — and it’s worth addressing directly because it comes up frequently in financial services and healthcare organizations.
The most common pattern: Purview handles Microsoft 365 compliance, DLP, sensitivity labeling, and information protection across Teams, SharePoint, and Exchange. Collibra handles the enterprise data catalog and governance workflows across structured data assets, warehouses, and operational systems. The two platforms coexist with some integration, but they serve different functions rather than competing head-to-head.
This isn’t an ideal architecture — it adds licensing cost, creates two separate user experiences, and requires governance knowledge in two platforms. But for organizations with a mature Collibra implementation that are expanding into Microsoft Fabric or deploying Copilot, Purview often becomes necessary regardless. Purview’s integration with Fabric and OneLake is deep enough that governing a Fabric-based data lakehouse without it creates meaningful gaps.
The question to ask is whether your primary governance challenge is data catalog and stewardship (Collibra’s domain), compliance and information protection across Microsoft workloads (Purview’s domain), or both. Organizations that answer “both” often end up with both platforms, whether they planned to or not. Being deliberate about the division of responsibility — rather than letting it happen organically — is the difference between a coherent governance architecture and a confusing one. Kanerika’s Microsoft Fabric and data governance practices have designed these hybrid architectures for enterprise clients across multiple industries.
Industry-Specific Recommendations A single ‘best overall’ verdict doesn’t work here. The right platform for a hospital system in regulated HIPAA territory looks completely different from what makes sense for a SaaS company running on AWS and Snowflake. Here’s how the decision typically breaks down by industry, based on Kanerika’s implementation experience:
Industry Recommended Primary Reason Watch Out For Financial Services Collibra or Purview Deep regulatory audit trails, lineage requirements, policy complexity Collibra’s adoption challenges; Purview’s limited non-Azure lineage Healthcare / Life Sciences Collibra HIPAA compliance depth, clinical data governance complexity Long implementation timeline before clinical teams see value Manufacturing Purview Often Microsoft-aligned; operational data governance is typically less complex Weaker cross-platform coverage if SAP is the primary system Retail / E-commerce Alation or Purview Discovery and business-user adoption often the primary driver Alation’s compliance depth if GDPR or PCI-DSS is heavily scrutinized Technology / SaaS Alation Multi-cloud data estates, engineering-led data culture, fast deployment May outgrow Alation’s governance depth as compliance requirements mature Public Sector / Government Purview FedRAMP alignment, existing M365 investment, Microsoft ecosystem fit Cross-agency data sharing governance may need Collibra augmentation
These are starting points, not fixed answers. A manufacturing firm with a complex multi-system ERP environment and serious GDPR exposure looks different from one running a Microsoft-first stack in a single geography. But if you’re orienting a shortlist, your industry is usually a reasonable first filter.
The Decision Framework: 5 Questions That Actually Matter Before running a feature comparison, answer these five questions. Your answers will narrow the field faster than any product demo.
1. What percentage of your data estate runs on Microsoft infrastructure? If the answer is 70%+, Purview is the starting point. Below 50%, and you’re evaluating it as a supplementary tool rather than a primary platform.
2. What is your primary governance driver?
Data discovery and business-user adoption → Alation Compliance + security integrated with existing Microsoft licensing → Purview 3. How mature is your data governance program today? No formal governance yet → Alation (adoption over enforcement). Documented policies, some stewardship roles → Purview or Alation. Mature program with dedicated governance team → Collibra.
4. What is your realistic implementation budget and timeline? Under $150K total first-year spend or under 4-month timeline → rules out Collibra. Under 2 months → Alation or Purview only. Willing to invest $300K+ over 18 months for deep governance infrastructure → Collibra is viable.
5. What does your team look like? No dedicated governance admin → Alation or Purview. One or two governance team members → Purview. A full governance team with executive sponsorship → Collibra.
If you answered these and landed consistently on one platform, the decision is probably clearer than you thought. If you got mixed answers, the next section will help you sort out the edge cases.
When to Choose Each Platform 1. Microsoft Purview : Your data estate is predominantly on Azure, Microsoft 365, or Microsoft Fabric You need unified security, compliance, and governance under one vendor relationship You’re already paying for Microsoft enterprise agreements — marginal cost is low Compliance requirements map to standard frameworks (GDPR, HIPAA, PCI-DSS) that Purview covers natively You’re rolling out Microsoft Fabric or Copilot and need governance that integrates from day one Your organization needs DLP and information protection tied directly to data governance 2. Collibra: Your organization has complex, multi-domain governance needs across heterogeneous systems You operate in a heavily regulated industry where audit trails and policy workflow depth matter most You have the budget ($170K+ base) and the organizational capacity for a 6–12 month implementation Governance is a strategic initiative with executive sponsorship and dedicated resources 3. Alation: Your primary challenge is data discovery and getting business users to actually engage with governance You need faster time-to-value and a lighter implementation lift You work across 120+ data sources including AWS, Snowflake, Salesforce, and Databricks Self-service analytics adoption is as important as policy compliance The AI Governance Angle: Microsoft Purview vs Collibra vs Alation All three platforms are integrating AI governance capabilities, and this is where their different philosophies become most visible. But there’s something most comparison articles miss: Microsoft Fabric is forcing the hand of organizations that thought they had more time to decide. Enterprises building data lakehouses on Fabric are making a governance decision simultaneously — whether they realize it or not. Fabric’s OneLake architecture, its native Purview integration, and its increasingly central role in enterprise analytics mean that organizations choosing Fabric as their data platform are implicitly choosing Purview as their governance foundation. You can supplement it with Collibra or Alation, but the Fabric-Purview connection is tight enough that trying to govern OneLake without Purview creates real gaps in data lineage , access control, and compliance. For Databricks-heavy environments, Databricks Unity Catalog can complement or partially substitute Purview for governance across lakehouse workloads.
This doesn’t mean Purview wins by default for Fabric shops. But it does mean the governance platform decision and the data platform decision are more connected than they used to be. If your organization is evaluating Fabric — or already running it — Purview’s role in that architecture is worth factoring in before you commit to a standalone Collibra or Alation implementation.
Beyond Fabric, Purview has moved most aggressively on AI governance overall, adding AI-specific governance features tied to Microsoft 365 Copilot and Azure AI. As enterprises deploy Copilot across Teams, SharePoint, and business applications, Purview provides the governance layer controlling what data Copilot can access and generating audit trails for AI-assisted decisions. For organizations already running Microsoft’s AI tools , this is a genuine advantage that neither Collibra nor Alation can fully replicate today.
Collibra’s AI governance focuses on automated workflow and policy management — using AI to reduce the manual burden on data stewards. It also supports governing AI models and datasets in regulated industries where explainability and compliance documentation are non-negotiable. This aligns with Collibra’s core strength: organizations that need governance to be programmatic, auditable, and defensible.
Alation positions itself as AI-ready, helping organizations govern both traditional data and AI/ML assets. Its strength is making model metadata discoverable and contextualizing AI outputs within broader data lineage. For teams building RAG pipelines or agentic AI workflows, Alation’s catalog-first approach to AI asset management is a practical fit.
With over 1,000 AI-related regulations now active across 69 countries, the AI governance question has moved well past theoretical. The data governance trends shaping 2026 are clear — organizations deploying enterprise AI without a governance layer are accumulating compliance risk faster than most procurement teams realize. The data governance pillars that underpin responsible AI programs aren’t optional anymore for enterprise data teams.
Implement Data Governance with Kanerika Kanerika is a Microsoft Solutions Partner for Data & AI with a dedicated practice around Microsoft Purview implementation . The team has deployed Purview for enterprises in financial services, healthcare, manufacturing, and retail, including a documented implementation for a leading bank that used Purview to transform data governance across a complex, multi-system environment. Details of that engagement are available in Kanerika’s Purview banking case study .
Kanerika’s Purview practice includes three accelerators built to reduce implementation time and extend Purview’s governance coverage:
KANGovern accelerates business glossary development with pre-built industry templates covering healthcare, financial services, manufacturing, and retail. It uses AI to identify and suggest relevant business terms from existing documentation, reducing glossary build time significantly compared to manual configuration. The resulting glossary integrates directly with Purview and makes business terms accessible within analytics tools and data platforms.
KANGuard handles data security and access control. It applies sensitivity labels, encryption, and access policies aligned to regulatory requirements, and monitors for risky data transfers in real time.
KANComply manages the compliance framework layer, mapping Purview policies to specific regulatory requirements (HIPAA , GDPR , PCI-DSS), generating audit-ready documentation, and maintaining ongoing compliance reporting.
For organizations evaluating Purview but unsure whether their environment is ready, Kanerika offers an initial assessment covering current data governance gaps, integration architecture, and a rollout roadmap. For organizations that have chosen Collibra or Alation and need implementation support alongside Purview, Kanerika’s data governance practice covers all three platforms and hybrid environments.

FAQs Can Microsoft Purview replace Collibra? For Microsoft-first organizations, Purview covers a significant portion of what Collibra offers — cataloging, compliance, and lineage within Azure and M365 environments. For multi-cloud or heterogeneous data estates with mature governance needs, Collibra still offers workflow depth that Purview doesn’t match. The answer depends heavily on how much of your data lives outside the Microsoft ecosystem and how complex your stewardship workflows need to be.
Is Alation better than Collibra for data governance? Alation is generally easier to adopt and faster to deploy. Collibra is deeper on policy management, workflow automation, and audit trails. For organizations where compliance enforcement is the primary driver, Collibra typically wins. For organizations where adoption and data quality visibility are the primary challenge, Alation is often the stronger choice.
How long does Microsoft Purview implementation take? A focused Purview deployment covering a specific use case — sensitive data classification across Azure and M365, for example — typically takes 2–4 months. A full enterprise rollout across multiple data sources and business units takes longer. Kanerika’s approach is to start with a pilot use case that demonstrates value before scaling.
What is the real total cost of ownership difference between Collibra and Alation? Base licensing is similar, but Collibra’s TCO is significantly higher due to longer implementation timelines, additional module licensing for lineage and data quality, and ongoing admin requirements. For context on why enterprises invest heavily in governance infrastructure: the average cost of a data breach reached $4.88 million in 2024, a 10% increase year-over-year, according to IBM’s Cost of a Data Breach Report. Alation typically reaches business value faster at lower total cost, particularly for organizations where governance maturity is still developing.
Does Microsoft Purview support non-Microsoft data sources? Yes — Purview supports AWS S3, GCP, Snowflake, Salesforce, SAP, and others. But cross-platform coverage is more reliable within the Microsoft ecosystem. Organizations with significant AWS or GCP workloads should evaluate how well Purview’s connectors work for their specific environment before committing.
How does Collibra handle federated data governance? Collibra supports federated models where individual business domains manage their own data products within a central governance framework. Each domain operates as a self-contained unit with its own policies while the central team maintains organization-wide consistency. This is one of Collibra’s strongest differentiators for large enterprises with decentralized data ownership models. It maps reasonably well to data mesh architectures where individual domains own and publish their data products.
What are KANGovern, KANGuard, and KANComply? These are Kanerika’s three accelerators for Microsoft Purview implementations. KANGovern handles business glossary creation with AI-assisted term identification and industry templates. KANGuard manages data security, access controls, and sensitivity labeling. KANComply handles compliance framework mapping and audit-ready reporting. Together they reduce typical Purview implementation time and extend governance coverage for specific regulatory requirements.
Are all three platforms suitable for regulated industries like financial services or healthcare? All three support regulated industry compliance, but to different depths. Collibra has the most comprehensive audit trail and policy enforcement for financial services and life sciences. Purview has strong coverage for standard compliance frameworks and integrates with Microsoft’s security stack. For Databricks-centric environments, Databricks regulatory compliance via Unity Catalog is worth evaluating as a complementary layer. Alation is increasingly used in regulated industries but is generally not the first choice where audit trail depth is the primary driver.
How does each platform handle data governance for AI and ML workloads? Purview is furthest ahead for governing Microsoft Copilot and Azure AI workloads. Collibra has strong automated policy management for governing AI datasets in regulated environments. Alation focuses on making AI model metadata discoverable and contextualizing AI outputs within data lineage. For organizations building AI programs on the Microsoft stack, Purview’s AI governance integration with Copilot is currently the most production-ready option.
