Data Loss Prevention

Know where your sensitive data lives, how it moves, and who touches it. We implement DLP programs that protect your most valuable information without choking productivity.

Data Is Your Most Valuable — and Most Vulnerable — Asset

Every organization handles sensitive data: customer PII, financial records, intellectual property, health information, trade secrets, and strategic plans. This data is under constant threat — not just from external attackers and ransomware operators, but from accidental exposure by employees, misconfigured cloud storage, shadow IT applications, and insider threats both malicious and negligent.

Data Loss Prevention is the discipline of identifying sensitive data, monitoring how it is used and shared, and enforcing policies that prevent unauthorized disclosure. A well-implemented DLP program does not just block data exfiltration — it gives you visibility into data flows you did not know existed, enabling better risk management, compliance, and governance.

Mjolnir Security designs, implements, and manages DLP programs that are practical and effective. We have seen too many organizations deploy DLP tools that generate thousands of false-positive alerts, frustrate users with overly aggressive blocking, and eventually get disabled by IT teams who cannot manage the noise. Our approach starts with understanding your data, your workflows, and your risk tolerance — then builds policies that protect what matters without creating operational friction.

DLP Program Components

Data Discovery & Classification

You cannot protect data you do not know about. We start every DLP engagement with a comprehensive data discovery and classification exercise:

Endpoint DLP

Endpoints are where data is created, modified, and most often leaked — through USB drives, personal email, cloud uploads, screen captures, and print operations. We deploy and tune endpoint DLP policies that monitor and control data movement on workstations and laptops:

Cloud DLP

With data distributed across Microsoft 365, Google Workspace, AWS, Azure, Salesforce, and dozens of SaaS applications, cloud DLP is essential. We implement DLP policies across your cloud ecosystem:

Policy Management & Tuning

DLP policies must evolve with your business. We provide ongoing policy management including regular tuning to reduce false positives, new policy development as data types and workflows change, exception management with proper approval and documentation, and incident review to identify trends and refine detection logic.

Regulatory Alignment

Our DLP programs are designed to satisfy the data protection requirements of PIPEDA, PHIPA, PCI DSS, HIPAA, GDPR, SOC 2, and sector-specific regulations. We map DLP policies to specific regulatory controls and provide evidence of compliance for audit and assessment purposes.

🔎

Data Discovery

Find sensitive data wherever it lives — file shares, cloud storage, databases, email, and SaaS applications. Classify and label it according to your risk taxonomy.

🛡

Multi-Channel Protection

Endpoint, email, cloud, and network DLP policies that work together to prevent data leakage across every channel — without creating user friction or alert fatigue.

Managed DLP Operations

Ongoing policy management, tuning, incident review, and reporting. We operate your DLP program so you get protection without the operational overhead.

Protect Your Data Before It Leaves

Data loss is preventable. Let us build the DLP program that gives you visibility, control, and confidence over your most sensitive information.
