Data Classification

Compliance & Data Protection

Data Classification & Information Protection Services

Sensitive data lives everywhere your users do: email, Teams, SharePoint, endpoints, and the cloud. Ravenswood uses Microsoft Purview to classify, label, and protect it without slowing your business down.

What is Data Classification?

Know Your Data. Label It Once. Protect It Everywhere.

Data classification identifies, categorizes, and labels information based on its sensitivity and business value, so the right protections follow that data wherever it goes. Ravenswood builds these programs on Microsoft Purview Information Protection, covering data at rest in SharePoint and OneDrive, in use on devices, and in transit to cloud services and outside recipients.

Think of it as a courier that travels with every document: instead of locking files inside a perimeter, each file carries its own enforceable rules about who can open it, what they can do with it, and where it is allowed to go. That holds whether the file sits on an internal file share, lands in a partner’s inbox, or gets uploaded to a SaaS app.

Reduced Data Exposure Risk

Automatic labeling applies protection consistently instead of relying on users to make the right call.

Enforceable Handling Policies

Labels trigger DLP rules, encryption, and access controls that stay with the data across devices, cloud services, and external recipients.

Audit-Ready Visibility

A complete record of how sensitive data is classified, accessed, and shared supports HIPAA, CMMC, PCI DSS, and other requirements.

Zero Trust Data Security

Classification enables data-aware Conditional Access and insider risk controls. Without it, Zero Trust has a blind spot.

The Cost of Inaction

Why Data Classification Matters

Organizations that put off data classification rarely get a quiet grace period. Sensitive data keeps spreading, regulators keep raising the bar, and every unlabeled file is one that no policy can protect.

Data Leaves the Building Unprotected

Sensitive files are emailed to partners, saved to personal OneDrive folders, shared with vendors, and synced to endpoints. Perimeter security has no answer once data is already out.

Compliance Pressure Keeps Rising

CMMC 2.0, HIPAA, ITAR, and privacy frameworks all require proof that sensitive data is identified and controlled. Without classification, that proof means manual evidence gathering every audit cycle.

Exposure Becomes Liability

Ad hoc, manual handling of sensitive data does not scale. When something leaks, the result is legal and reputational damage that could have been prevented with consistent labeling.

Licensed Tools Sit Unused

Microsoft Purview is included in many Microsoft 365 licensing tiers. Organizations are often paying for classification, labeling, and DLP capabilities they have never turned on.

Every day of delay is another day of unlabeled data.

Problems We Solve

Security & Operational Challenges We Address

Ravenswood’s data classification services address the gaps that leave sensitive information unidentified, unlabeled, and unprotected across Microsoft 365 and beyond.

Unstructured Data Blind Spots

Most sensitive information lives in documents, spreadsheets, and emails rather than structured databases. Without a consistent way to classify it, that data is invisible to security controls and inconsistently handled from one team to the next.

Our Solution: We establish a clear, organization-wide classification standard and enable both user-driven and automatic labeling in Microsoft Purview, so documents and emails are classified consistently without depending on every user to get it right.

Data Leaving Company Walls

Files are routinely emailed to partners, shared with vendors, and downloaded to personal devices. Once a document leaves your environment, traditional access controls no longer apply and you lose the ability to govern what happens to it.

Our Solution: We implement Information Rights Management (IRM) controls that travel with the document itself, governing who can view, edit, forward, or print content even after it has been shared externally.

Inventory & Discovery Gaps

You cannot protect data you do not know exists. Years of accumulated file shares, SharePoint sites, and mailboxes often hold regulated or confidential content that no one has cataloged.

Our Solution: We scan file shares, SharePoint sites, Exchange, and other storage locations to surface sensitive data, then apply labels automatically so protection reaches content you may not know you had.

Malicious or Inadvertent Exposure

Data loss is just as likely to come from a well-meaning employee attaching the wrong file as from a malicious insider. Either way, the result is the same once the data is out.

Our Solution: We build Endpoint and Microsoft 365 DLP rules tied to sensitivity labels that intercept risky actions, such as external sharing, USB transfers, or uploads to unsanctioned apps, before data leaves your environment.

Our Approach

Assessment-Led Data Protection Methodology

Ravenswood follows a business-aligned methodology that produces a protection program built around your compliance environment and data landscape, not a generic label template.

1
Assessment and Strategy

Every engagement starts by understanding your regulatory obligations, data types, and business workflows. No two organizations handle sensitive data the same way, and the program is designed to fit yours.

  • Map regulatory requirements such as CMMC 2.0, HIPAA, ITAR, and privacy frameworks
  • Inventory data types, storage locations, and sharing patterns
  • Identify the highest-risk data and workflows to prioritize first
2
Design and Planning

With requirements defined, we establish the governance framework and translate it into a deployable Microsoft Purview architecture for your tenant.

  • Define classification tiers, retention schedules, and handling standards
  • Design the sensitivity label taxonomy and DLP rule sets
  • Configure sensitive information types, trainable classifiers, and retention labels
3
Implementation and Remediation

We validate the design through a controlled pilot before enforcing organization-wide, so policies are accurate and users are not caught off guard.

  • Pilot with a representative group and monitor for friction and false positives
  • Tune policies based on real-world results
  • Stage rollout across the organization to minimize disruption and maximize adoption
4
Ongoing Support

Data protection is not a one-time project. Regulations change, new data sources appear, and labels need to keep pace.

  • Flexible support options with blocks of hours
  • Continued access to Purview and compliance specialists
  • Help with policy tuning, new workloads, and emerging requirements such as Copilot readiness

FAQ

Frequently Asked Questions

Data classification is the process of identifying and labeling data based on its sensitivity. DLP is a set of policies that enforce actions—such as blocking a send or requiring justification—when sensitive data is handled in a risky way. They work together: claassification labels are what DLP rules act on. Without classification, DLP has no reliable signal to work from.

Microsoft Purview is built directly into Microsoft 365, meaning it integrates natively with Exchange, SharePoint, OneDrive, Teams, and Office applications. There is no separate product to install. Ravenswood configures your existing tenant to activate and properly tune these capabilities.

Timelines vary based on the size of your environment, the complexity of your data types, and how mature your existing policies are. A foundational label taxonomy and initial DLP ruleset can often be piloted within a few weeks. Full organization-wide rollout and enforcement typically follows in phases over one to three months.

No. While end-user labeling is an important part of a mature program, much of the classification work is handled automatically. Purview can apply labels based on content inspection, location, file type, and other conditions—without requiring user action. User-applied labels are most valuable for documents that require human judgment about sensitivity.

Yes. Microsoft Purview includes capabilities to scan on-premises file repositories and extend protection to data outside the Microsoft cloud. Ravenswood will assess your full data landscape during requirements gathering and design a solution that addresses your entire environment.

CMMC 2.0 requires organizations in the Defense Industrial Base to protect Controlled Unclassified Information (CUI). Data classification is a direct enabler of that requirement: it provides the mechanism to identify where CUI exists, apply appropriate protections, and enforce access and sharing controls through DLP and IRM—all of which map directly to CMMC 2.0 practices around access control, media protection, and configuration management.
