The Challenge

Data Is Your Most Valuable Asset — and Your Biggest Risk

Organizations today generate, store, and share more data than ever before. Yet most lack visibility into where sensitive data resides, who has access to it, and how it moves across cloud services, endpoints, and collaboration platforms.

Without a unified data governance strategy, enterprises face escalating regulatory penalties, insider threats, and reputational damage from data breaches exposing customer, financial, and intellectual property assets.

Solution Overview

Microsoft Purview: Unified Data Governance

CPS delivers a comprehensive data security practice built on the Microsoft Purview platform, providing end-to-end data classification, protection, loss prevention, and compliance management across your entire digital estate.

Unlike point solutions that address data security in isolation, the CPS Data Security offering leverages native integration between Purview, Microsoft 365, Azure, and Microsoft Defender to create a single, policy-driven data protection fabric.

High-Level Architecture

Data Security Reference Architecture

The CPS Data Security architecture operates across four integrated layers, each reinforcing the others to create defence-in-depth for organisational data assets.

Layer 1: Discovery & Classification

Microsoft Purview Data Map scans structured and unstructured data sources across Azure, Microsoft 365, AWS, and GCP. Sensitive Information Types (SITs) and trainable classifiers automatically identify PII, financial data, health records, and custom patterns. A central data catalogue provides a unified inventory of sensitive assets.

Layer 2: Labelling & Encryption

Sensitivity labels are applied automatically or manually through Microsoft Information Protection. Labels persist across Microsoft 365 apps, SharePoint, Teams, Exchange, and endpoints. Azure Rights Management enforces encryption, watermarking, and access restrictions, with visual markings to signal classification.

Layer 3: Data Loss Prevention (DLP)

Unified DLP policies protect endpoints, Exchange, Teams, SharePoint, OneDrive, and third-party cloud apps via Microsoft Defender for Cloud Apps. Context-aware policies evaluate content, user actions, and sensitivity labels before permitting sharing, copying, printing, or transfer, with real-time policy tips and audit trails.

Layer 4: Insider Risk & Compliance

Insider Risk Management detects anomalous data exfiltration using machine-learning driven sequence analysis. Communication Compliance, eDiscovery, and Audit enable monitoring, investigations, legal holds, and forensic analysis. Compliance Manager maps controls to GDPR, Kenya DPA, PCI-DSS, ISO 27001, SOC 2, and NIST CSF.
