Protect Sensitive Data Across Your Data Estate with Microsoft Purview
Protect Your Data Wherever It Lives, Moves, or Is Used
Most organizations don’t struggle with knowing they need data security; they struggle with where to start, what to enforce, and how to scale protection as risk grows, especially with AI in the mix.
ProArch’s Data Security services follow a three‑phase approach built around Microsoft Purview that meets organizations where they are. We start by aligning policy and priorities, move into enforced protection across Microsoft 365 and AI workloads, and then apply advanced controls where risk is highest.
Each phase stands on its own—but together, they turn data governance into real, enforceable security outcomes.

Data Security FAQs
What is data security, and why does it matter for my organization?
Data security is the practice of identifying sensitive data and enforcing controls that prevent unauthorized access, oversharing, or misuse—especially across collaboration tools and AI.
ProArch treats data security as a business decision first. We help organizations define what data matters and who should access it, then enforce those decisions using Microsoft Purview across Microsoft 365 and AI workloads.
What is Microsoft Purview, and how does it protect sensitive data?
Microsoft Purview is Microsoft’s unified platform for discovering, classifying, and protecting sensitive data across Microsoft 365, Azure, and AI experiences like Copilot.
ProArch implements Purview by establishing governance and data foundations first, then configuring labeling, DLP, Insider Risk Management, and DSPM for AI so protections are enforced in daytoday work, not just documented.
How can I prevent sensitive data from leaking through Microsoft 365 tools like Teams, SharePoint, or Copilot?
Sensitive data leakage is prevented by applying Purview DLP and labeling policies consistently across Microsoft 365 and AI tools.
ProArch configures Microsoft Purview controls across email, SharePoint, OneDrive, Teams, and Copilot to enforce protection based on data type, context, and user behavior.
This approach avoids blanket restrictions while ensuring sensitive data cannot be shared externally, accessed improperly, or surfaced by AI without the right protections.
How does Microsoft Purview help secure AI tools like Microsoft Copilot?
Microsoft Purview secures AI by enforcing data classification, access, and DLP controls when data is used in Copilot prompts and responses.
AI tools can only be trusted if their data access is governed. Purview ensures AI interactions respect existing permissions, sensitivity labels, and protection policies.
What types of sensitive data can Microsoft Purview detect and classify?
Microsoft Purview can automatically identify regulated, personal, financial, and businesscritical data.
This includes PII, financial information, credentials, healthcare data (PHI), contracts, intellectual property, employee data, and custom industryspecific data types.
ProArch customizes classification models to reflect real regulatory and operational needs rather than relying solely on default templates.
What’s the difference between data governance and data security?
Data governance defines the rules; data security enforces them.
Governance determines what data exists, who owns it, how long it is retained, and how it may be used. Data security applies technical controls—classification, encryption, access restrictions, and DLP—to enforce those decisions.
ProArch delivers both ensuring data protection is intentional, defensible, and consistently enforced across Microsoft 365 and AI workloads.
How long does it take to implement data security with Microsoft Purview?
ProArch uses a three-phase model:
- Foundation 1-month: Data classification models, retention policies, and governance alignment
- Accelerator 3-months: Sensitivity labels, DLP, and Microsoft 365 + AI enforcement
- Advanced 4-months: Insider Risk Management, privilege based threats, and advanced AI governance
Each phase stands on its own, allowing organizations to start small and expand based on risk and priorities.
Is data security worth the investment for midsized organizations?
Yes—midsized organizations face the same data and AI risks as enterprises, often with fewer resources.
ProArch’s data security services are designed for organizations of all sizes, delivering measurable risk reduction through a phased approach that avoids unnecessary complexity.
How do I get started with Microsoft Purview for data security?
The best way to get started with Microsoft Purview is by understanding where your sensitive data lives and how it’s being used before enforcing controls.
ProArch helps organizations start with a data security assessment or Microsoft funded Data Security Envisioning Workshop to identify risk, establish governance, and define a clear roadmap.
From there, we implement Microsoft Purview in phased steps—starting with visibility and progressing to protection—so security improves without disrupting the business.
Do you offer an initial data security assessment or audit?
Yes—ProArch begins most engagements with a data security assessment as part of the Foundation phase.
This assessment evaluates current data exposure, governance gaps, and compliance risk, then maps Microsoft Purview capabilities to business priorities.
Organizations receive a clear, phased roadmap they can act on immediately, whether or not they proceed to full enforcement.
Why should data governance be established before enforcing data security controls?
Security controls fail when they are turned on without business alignment.
ProArch’s data governance services ensure data policies are approved, understood, and defensible before technical enforcement begins. This reduces user friction, improves adoption, and results in more sustainable security outcomes.
Is Microsoft funding available for data security initiatives?
If eligible, Microsoft funding is available through the Data Security Envisioning Workshop.
ProArch delivers a Microsoft funded Data Security Envisioning Workshop that uses Microsoft Purview to identify data security and compliance risks and provide a clear, prioritized roadmap.
Eligibility depends on licensing and scope, and ProArch helps determine qualification during planning. Learn more here.
