Data Loss Prevention Implementation Services
Your sensitive data is one careless click away from leaving your organization for good. Stop accidental leaks, insider threats, and unauthorized exfiltration before they happen — without slowing your business down.
Sensitive Data, Identified. Risky Actions, Blocked.
Data loss prevention (DLP) is a set of policies, technologies, and controls designed to detect and prevent the unauthorized access, sharing, or transfer of sensitive information. It is not a single tool you switch on—it is a proactive, layered program that must be designed, tuned, and maintained to be effective.
Ravenswood builds DLP programs on Microsoft Purview, Microsoft's unified data governance and compliance platform. Purview gives organizations a centralized place to discover sensitive data, enforce protection policies, and demonstrate compliance—all within the Microsoft 365 environment your teams already use.
Reduced Exfiltration Risk
Real-time policy enforcement blocks unauthorized sharing, uploads, and transfers before sensitive data leaves your control.
Insider Threat Protection
DLP rules tied to sensitivity labels catch both malicious and well-meaning employees before risky actions become incidents.
Consistent Enforcement
Policies apply uniformly across email, endpoints, cloud apps, and external sharing — closing the gaps that point solutions leave open.
Compliance-Ready
Detailed policy logs and incident reports support audit requirements across HIPAA, CMMC, PCI-DSS, and other regulatory frameworks.
Why DLP Matters
Organizations that operate without a mature DLP program face compounding exposure. The longer sensitive data moves through your environment unmonitored, the greater your exposure becomes. Contact Ravenswood Technology Group for a free consultation.
Data Outpaces Your Controls
Information flows through Teams chats, SharePoint, OneDrive, email, and increasingly AI chat tools like ChatGPT and Claude — often simultaneously and with no policy enforcement in place.
Costly Financial Impact
Breaches and regulatory violations can result in millions of dollars in fines, litigation costs, and remediation expenses, on top of lasting damage to customer trust and brand reputation.
Compounding Regulatory Obligations
GDPR, HIPAA, PCI-DSS, and CMMC 2.0 each carry specific data protection requirements — and falling short of any one of them creates legal, financial, and reputational exposure that extends well beyond IT.
No Real Visibility
There's no reliable way to know where sensitive data lives, who has access to it, or where it's headed once it leaves your direct control.
Don't wait for an incident to force action.

Most organizations know they have a data protection gap. The challenge is identifying exactly where the exposure is and closing it before an incident occurs. Ravenswood's data loss prevention services are designed to address the most common and costly risks:
Unstructured Data Blind Spots
Sensitive information often hides in plain sight — buried in email threads, Teams messages, or files scattered across cloud storage and on-premises file servers.
Our Solution: We deploy automated discovery that surfaces sensitive data you didn’t know existed, so nothing slips through unprotected.
Regulatory Non-Compliance
Organizations subject to GDPR, HIPAA, PCI-DSS, or CMMC 2.0 requirements must be able to demonstrate active controls over sensitive data.
Our Solution: We build a structured DLP program with the policy enforcement and documentation needed to pass an audit with confidence.
Shadow IT and Unmanaged Endpoints
Sensitive files can easily move to unauthorized USB drives, personal cloud accounts, unsanctioned AI chat tools, or unapproved applications without the right endpoint controls in place.
Our Solution: We close these often-overlooked gaps with endpoint DLP policies that govern exactly where sensitive data is allowed to go.
Accidental and Malicious Data Leaks
Whether an employee mistakenly attaches a file containing customer PII to an external email or a malicious insider deliberately exfiltrates proprietary data, the consequences can be severe.
Our Solution: We implement DLP policies that intercept both scenarios in real time, before data ever leaves your environment.
Assessment-led Methodology
Ravenswood takes a structured, layered approach to data loss prevention—starting with understanding where your data lives and building outward to enforce protections at every point of potential exposure.
Unified Data Discovery
Before you can protect your data, you need to find it. We scan Exchange, SharePoint, OneDrive, and Teams to identify sensitive information across your environment.
- Deploy built-in and custom Sensitive Information Types within Microsoft Purview
- Identify patterns including credit card numbers, health records, and proprietary IP
- Build a clear picture of where sensitive data resides and how it’s used
Real-Time Intervention
Once your data is mapped, we implement DLP policies that act as automated guardrails against risky actions.
- Deliver in-app Policy Tips that coach users at the moment of a potential violation
- Block unauthorized sharing and exfiltration with documented override options
- Restrict risky endpoint activity, including USB transfers and unapproved app sharing
Integrated Information Protection
DLP works best as part of a broader strategy. We combine Purview DLP with Microsoft Information Protection for unified, persistent protection.
- Apply sensitivity labels that automatically classify and encrypt sensitive files
- Ensure protection travels with data even after it leaves your environment
- Extend coverage to third-party apps through Microsoft Defender for Cloud Apps
Adaptive, Risk-Based Controls
Not all users or situations carry the same risk. We implement Adaptive Protection to dynamically respond to risky behavior.
- Apply stricter controls to users exhibiting risky behavior patterns
- Integrate directly with Insider Risk Management for early threat detection
- Mitigate potential data exfiltration before it becomes a breach
Measurable Improvements Across Security, Operations, and Compliance
A well-implemented DLP program delivers benefits that go beyond blocking individual policy violations. Organizations that partner with Ravenswood can expect:
Audit
Ready InfrastructureAudit-Ready Compliance Infrastructure
You'll have the visibility, policy logs, and reporting documentation required to satisfy GDPR, HIPAA, PCI-DSS, and CMMC 2.0 audits. When regulators or auditors ask how sensitive data is protected, you'll have a clear, defensible answer.
Less
Alert NoiseReduced Alert Fatigue
Poorly tuned DLP policies generate noise that security teams learn to ignore — undermining the entire program. We tune policies to balance robust data protection with employee productivity, so the alerts that do fire actually matter.
Protection
Travels With DataPersistent File-Level Protection
Sensitivity labels and encryption travel with your documents wherever they go, ensuring protection doesn't stop at your network perimeter. Even after a file is shared externally or downloaded to an unmanaged device, your controls remain in effect.

Frequently Asked Questions
What is the difference between DLP and Microsoft Information Protection (MIP)?
DLP and MIP are complementary, not competing. DLP focuses on detecting and preventing policy violations in real time—blocking a file from being emailed to an unauthorized recipient, for example. MIP focuses on classifying and labeling data so it carries protection with it wherever it goes and is an important tool in the overall DLP policy. Ravenswood implements both together as part of a unified data protection program through Microsoft Purview.
Does DLP work with on-premises environments?
Microsoft Purview DLP is primarily cloud-native and optimized for Microsoft 365 workloads. However, it does support on-premises file shares and other repositories, like SharePoint Server, through the Purview Information Protection scanner. For organizations with significant on-premises infrastructure, we assess your environment and recommend the appropriate coverage model.
How long does a DLP implementation take?
Timelines vary based on the complexity of your environment, the number of data sources in scope, and your compliance requirements. A foundational DLP deployment can be completed in a matter of weeks, while a comprehensive program that includes endpoint controls, MIP integration, and Insider Risk Management may take longer. Ravenswood provides a clear project timeline during the assessment phase.
Do we need additional Microsoft licenses for DLP?
Many DLP capabilities are included in Microsoft 365 E3 and above. Advanced features—such as Adaptive Protection and Insider Risk Management—require Microsoft 365 E5 Compliance or equivalent add-ons. During our engagement, we audit your current licensing to ensure you are activating everything you already own before recommending additional investment.
What happens after implementation?
Deployment is the beginning, not the end. Ravenswood provides post-deployment policy tuning to reduce false positives, address emerging risks, and adapt controls as your organization changes. We also offer ongoing support to help your team manage and maintain the program over time.
