Data Security Services
Microsoft Purview-powered data protection solutions to prevent data leaks, reduce insider risk and secure AI workloads.
Protect Your Data Wherever It Lives, Moves, or Is Used
Many organizations use Microsoft 365 and are preparing to roll out or scale Copilot, but lack clear visibility into which sensitive data is being overshared, exposed or surfaced by AI. Data sprawl, unclear classification, and underused Microsoft Purview capabilities are creating risk faster than teams can respond.
While organizations recognize the need for data security, many struggle with where to start, what to enforce, and how to scale protection as risk grows.
ProArch’s Data Security services follow a three‑phase approach built on Microsoft Purview. We align policy and priorities, enforce protection across Microsoft 365 and AI workloads, and apply advanced controls where risk is highest - delivering practical, enforceable data security outcomes.

Data Security FAQs
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 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 day today work, not just documented.
How long does it take to implement data security with Microsoft Purview?
There is no one‑size‑fits‑all timeline. At ProArch, we don’t treat Microsoft Purview as a switch you turn on. We start by understanding where sensitive data lives, how it’s shared, and how AI and Copilot are used.
Based on that, we implement controls in phases starting with visibility and guardrails, then scaling enforcement without disrupting collaboration.
Will Microsoft Purview slow down employees or block collaboration?
No. When implemented correctly, Microsoft Purview protects sensitive data without interrupting everyday work.
ProArch focuses on targeted, risk-based controls rather than broad restrictions, allowing employees to collaborate normally in Teams, SharePoint, and Copilot while sensitive data is automatically protected in the background.
Do we need Microsoft E5 to use Microsoft Purview for data security?
No. Core Microsoft Purview data security capabilities are available with Microsoft 365 E3 and E5 plans. Some advanced features, such as Insider Risk Management and AI-focused protections, require E5.
ProArch helps you make the most of your existing licenses and recommends upgrades only where they deliver clear business value.
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.
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.
What types of sensitive data can Microsoft Purview detect and classify?
Microsoft Purview can automatically identify regulated, personal, financial, and business critical data.
This includes PII, financial information, credentials, healthcare data (PHI), contracts, intellectual property, employee data, and custom industry specific 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.
Why should data governance be established before implementing 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 Purview data security too complex or expensive for my organization?
No. Microsoft Purview is designed to scale with your organization. ProArch helps reduce complexity by using the Microsoft security capabilities you already have and rolling out controls in phases.
This approach avoids tool sprawl, limits unnecessary cost, and delivers measurable risk reduction without enterprise‑level overhead.
What is data security, and why does it matter for my organization?
Data security is the practice of identifying sensitive data and enforcing controls to prevent unauthorized access, oversharing, or misuse. It matters because data now lives across Microsoft 365, collaboration tools, and AI like Copilot.
ProArch helps organizations turn data security into enforceable, business‑aligned controls using Microsoft Purview protecting sensitive information without slowing collaboration.
