Sensitive information had become distributed across the organization’s growing data estate, making it difficult to understand where business-critical data resided and how it moved through the environment.

The organization needed to

• Identify existing and hidden data security risks.
• Discover privacy data, personal identifiers, intellectual property, and other sensitive information.
• Locate sensitive and stale data across Microsoft 365 repositories.
• Detect unusual or suspicious activity involving sensitive information.
• Prioritize the risks requiring attention.
• Map those risks to the appropriate Microsoft Purview capabilities.

ProArch delivered a structured Microsoft Data Security Engagement, deploying a targeted set of Microsoft Purview capabilities within the client’s environment.

The engagement demonstrated how the platform could improve sensitive data discovery, surface security risks, and guide prioritized remediation.

• Automated Sensitive Data Discovery
  ProArch worked with the organization to define the sensitive information types most relevant to its business. Automated discovery capabilities were then enabled to identify sensitive information across Microsoft 365 repositories, surface stale data, and monitor unusual activity involving protected information.
• Evidence-Based Risk Prioritization
  The Data Security Check gave stakeholders a clearer, fact-based view of the organization’s data security posture. Rather than relying on assumptions, the organization could identify which risks were most significant and determine where mitigation efforts should begin.
• Microsoft Purview Roadmap
  ProArch mapped the identified risks to relevant Microsoft Purview products and services. The resulting recommendations established practical next steps for strengthening data protection and compliance.

Additional options—including Compliance Manager, on-premises data scanning, and Windows endpoint risk discovery—were identified as potential ways to extend protection across the organization’s broader data estate.

• Improved sensitive-data visibility
  The organization gained a clearer view of where sensitive data resides and how it is used across Microsoft 365 repositories.
• Surfaced hidden data risks
  The engagement revealed previously obscured data security exposures and unusual activity involving protected information.
• Enabled evidence-based prioritization
  Stakeholders could focus mitigation efforts on the risks with the greatest potential business impact.
• Clarified the Microsoft Purview path
  Identified risks were mapped to specific Microsoft Purview capabilities, creating practical next steps for protection and compliance.
• Established a foundation for broader protection
  The roadmap gives the organization a structured way to extend protection to additional endpoints and on-premises data sources as needed.
