Securing Unstructured Data Post-Merger: A CISO’s Guide

A merger joins two unstructured estates with different classification standards, security controls and retention rules, and the gap between them is where risk concentrates. This guide sets out where a CISO should start: unified classification first, then regulatory obligations, then the access model a Zero Trust programme will eventually need.

Integrating unstructured data after a merger is no small task. The right tools and approach can help you secure your organization’s data, ensure compliance, and prepare for a Zero Trust future.

Unstructured Data Integration: Where to Begin?

Merging two companies brings together vast amounts of unstructured data—like emails, documents, and multimedia files—often residing in different systems with inconsistent classification standards and varying security protocols. This fragmented data landscape creates significant risks, including security vulnerabilities and regulatory non-compliance, if not managed properly.

This complexity is further compounded by the interplay of three key teams—IT, Security, and Data—each with distinct priorities. This dynamic mirrors the Three-Body Problem in physics, where multiple forces pull in different directions, creating unpredictable outcomes:

  • IT: Prioritizes infrastructure and performance.
  • Security: Focuses on protection and compliance.
  • Data: Drives insights and innovation.

Without alignment, these competing priorities can lead to unclear ownership, siloed efforts, and operational inefficiencies.

Unified data classification: Establish control from the start

To address this unpredictability, unstructured data must be classified and managed consistently from the outset. Without this foundation, organizations risk security breaches, regulatory failures, and missed opportunities for innovation.

How DataXray Helps: DataXray automates the discovery and classification of unstructured data across systems, ensuring all teams—IT, Security, and Data—have a shared understanding of the data landscape.

Meet regulatory demands

What’s at Stake: Managing unstructured data under regulations like GDPR, CCPA, and HIPAA can feel overwhelming, especially post-merger. Compliance becomes even more challenging when teams operate in silos, leading to gaps in visibility and control.

Streamlining Compliance with DataXray:

  • Comprehensive Data Scanning: DataXray scans data sources to locate unstructured data wherever it resides, including file shares, document repositories, email servers, and cloud storage like AWS S3, Google Drive, or Microsoft OneDrive.
  • Advanced Classification Techniques: Once data is identified, DataXray uses algorithms to automatically categorize it based on content and context. For example, it flags PII (e.g., social security numbers, credit card details) and document types like CVs, invoices, and contracts.
  • Audit-Ready Reporting: DataXray generates detailed reports that can be easily exported for compliance audits, reducing manual workloads and minimizing non-compliance risks.

Laying the Foundation for a Zero Trust Future

Moving to a Zero Trust model requires careful coordination across IT, Security, and Data teams. Accurate classification and protection of unstructured data are non-negotiable for success.

How DataXray Helps: DataXray identifies and classifies data assets, prioritizes those containing sensitive information, and integrates seamlessly with DLP and catalog tools. This supports:

  • IT teams: By maintaining infrastructure performance.
  • Security teams: By enforcing access controls.
  • Data teams: By driving actionable insights.

Moving Forward: Practical Steps for CISOs

Utilize DataXray to address the Three-Body Problem and unite IT, Security, and Data teams around a shared foundation. With the right tools, your organization can achieve stability and unlock the value of its unstructured data.
