Microsoft Purview is Microsoft’s unified data security and governance platform. It helps organizations discover sensitive data, classify and protect it, prevent data loss, and detect insider risk across Microsoft 365 and connected cloud environments.
Microsoft Purview helps organizations understand where sensitive data exists and apply governance and protection controls across Microsoft 365 and cloud workloads.

Microsoft Purview is Microsoft’s unified platform for data security, governance, risk, and compliance.
It helps organizations discover where sensitive data lives, classify and label it, apply protection policies, prevent data loss, detect insider risk, and govern data across Microsoft 365, cloud, SaaS, on-premises, and AI environments.
Microsoft Purview is used to discover sensitive data, classify and label information, apply encryption and access controls, prevent data loss, manage retention, investigate risky user activity, support compliance, and prepare Microsoft 365 data for secure AI and Copilot adoption.
Microsoft Purview Information Protection helps organizations classify, label, and encrypt sensitive data so protection follows the file or message wherever it goes.
It is used to apply sensitivity labels across Microsoft 365 apps and services, helping reduce accidental exposure when data is shared, downloaded, forwarded, or used by AI tools.
Why it matters: Protection stays with the data, not just the location. Even if a file is downloaded, copied, or forwarded, the label and encryption remain intact.
Purview Data Loss Prevention helps prevent sensitive data from being shared, copied, or exposed inappropriately without blocking legitimate work.
DLP policies can be applied across:
DLP policies adapt based on context, user behavior, and risk.
Why it matters: Sensitive data is protected without killing productivity.
Microsoft Purview Insider Risk Management correlates user behavior and activity signals to identify potential data misuse early whether intentional or accidental.
Security teams gain visibility into risk while maintaining appropriate privacy controls.
Why it matters: Most data incidents start from inside the organization. Purview gives security teams early signals, not post-incident logs.
Microsoft Purview is deeply integrated into Microsoft 365 workloads, including Outlook, Teams, SharePoint, OneDrive, and endpoints.
This integration ensures that Microsoft 365 Copilot and supported AI experiences respect existing permissions, sensitivity labels, and compliance controls.
Microsoft continues to expand Purview with Data Security Posture Management (DSPM), DSPM for AI, and AI-powered data security investigation capabilities, strengthening visibility and prioritization across the data estate.
Microsoft Purview helps protect the data that Microsoft 365 Copilot can access and reference by applying the same Microsoft 365 security and compliance controls across the underlying content (Exchange, SharePoint, OneDrive, Teams, and endpoints).
For most organizations, deploying Purview is a critical step in making AI adoption safe, explainable, and controllable. It ensures AI works within defined data boundaries rather than amplifying existing governance gaps.
Understand how to prevent oversharing and protect sensitive data.
Data security incidents can happen anytime, anywhere. In most organizations, they typically fall into one of four scenarios:
| Root Cause | What It Looks Like in Practice |
| Lack of data visibility
When organizations don’t know where sensitive data lives or how it’s used, that data is at risk of exposure, misuse, or exfiltration. |
In many of our client engagements, customers acknowledge that their data is spread across collaboration tools, cloud services, endpoints, AI apps, and legacy systems without a unified way to discover, classify, or monitor it. |
| Malicious insider activity
A user with legitimate access may intentionally attempt to extract or misuse sensitive data. |
During a recent engagement with a healthcare client, ProArch conducted a Microsoft Purview Cloud Security Insights (CSI) assessment and found a large amount of sensitive PII and PHI moving in and out of their Microsoft 365 environment. While the activity may not be inherently malicious, it can present considerable risks. |
| Unintentional user actions
Well-meaning users may accidentally overshare or make sensitive documents visible to the wrong audience. |
Common scenarios discussed during proposal engagements include:
|
| Copilot and AI tools Usage
Using Copilot and AI tools without proper data control and governance |
Many organizations rush to deploy Microsoft 365 Copilot while data remains over-permissioned, inconsistently labeled, and governed differently across platforms. As a result, Copilot mirrors these issues—exposing sensitive content to unintended audiences. Common issues include:
|
Regardless of how an incident occurs, the underlying issue is usually the same: most organizations lack visibility into how their data is accessed and used.
This is why most organizations we work with at ProArch are investing in data security services using Microsoft Purview focused on discovery, classification, governance, and monitoring.
Without these, it’s impossible to accurately understand or manage data risk.
Organizations often turn to Microsoft Purview when:

Microsoft Purview is not a single SKU; it is delivered across Microsoft 365 plans and add-on suites.
“Does our Microsoft 365 license include Microsoft Purview?”
It’s one of the most common questions we hear, and the answer is almost always yes. What varies is how much of it you can use, and that comes down to your Microsoft 365 license.
With Microsoft 365 E3, you get the basic features of Microsoft Purview like:
It helps teams understand where sensitive data lives and begin building a data protection strategy.
With E5, organizations can move beyond manual controls and enable advanced, automated data protection, including:
This level of licensing is especially important for organizations handling regulated data, intellectual property, or high‑risk internal data flows.

Not every employee needs advanced Purview capabilities. Many organizations take a tiered approach, using:
This approach allows organizations to maximize value from existing licenses, while selectively enabling advanced protections where risk and regulatory pressure are highest.
If you're not ready to invest in full advanced capabilities, Microsoft offers flexible add-on options:
This approach allows organizations to maximize value from existing licenses while selectively enabling advanced protections where risk and regulatory requirements demand it without over-licensing.
As organizations accelerate their AI usage and adoption, ProArch helps organizations protect sensitive data across their data estate, including AI workloads by designing and operationalizing Microsoft Purview.
ProArch has built a repeatable, outcome driven approach that helps organizations discover risk, protect what matters most, and create a culture of data responsibility.
As a top Microsoft Solutions Partner, ProArch doesn’t just advise on Purview; we operationalize it. We’ve built real-world expertise across industries and deployed these solutions at scale for our own operations. That means we know what works.
