Data Security Assessment (Purview-led)

A Microsoft Purview - led assessment to identify data risk, improve protection controls, and create an implementable roadmap across labels, DLP, insider risk, and investigations.

Data security has expanded beyond documents in SharePoint. Sensitive information lives across Microsoft 365, endpoints, collaboration channels, and third‑party locations - and it increasingly interacts with AI-enabled workflows. Microsoft positions Microsoft Purview as a portfolio spanning data governance, data security, and data compliance, with data security solutions designed to help organisations monitor and protect information and manage data risk.
LW IT Solutions delivers a Purview-led data security assessment that converts technology capability into a practical plan. We baseline how sensitive data is classified and protected today, validate how policies behave in real user workflows, and evaluate how incidents and alerts are investigated and remediated. You receive a prioritised backlog and an implementation roadmap - focused on measurable risk reduction, evidence-friendly governance, and operational readiness for security teams.

Talk through your requirements and leave with a clear next-step plan.

Service Overview

Highlights

  • Purview-led assessment across labels, DLP, and data risk signals
  • Validation of controls against real user workflows, not just configuration
  • Clear linkage between technical controls and operational processes
  • Actionable backlog focused on risk reduction and evidence readiness
  • Aligned to how security teams actually investigate and respond to incidents

Business Benefits

  • Clear visibility of sensitive data risk and the most valuable controls to implement first
  • Reduced likelihood of accidental or intentional data loss through improved policy coverage and governance
  • Improved investigation and remediation capability for data incidents through defined workflows
  • More defensible configuration and evidence posture for assurance conversations and audits

Typical use cases

  • Preparing for a wider data protection or compliance programme
  • Improving confidence in Microsoft Purview DLP and labelling effectiveness
  • Responding to concerns about insider risk or data leakage
  • Supporting audit, assurance, or customer security questionnaires
  • Aligning data security controls with increased AI and collaboration usage

Objectives & deliverables

What Success Looks Like

  • Understand where sensitive data is exposed or insufficiently protected
  • Validate that data protection controls behave as intended in practice
  • Improve detection, investigation, and response for data security incidents
  • Establish a defensible and supportable data security operating model
  • Create a clear, prioritised roadmap for improving data protection

What You Get

  • Current-state data risk baseline (what data is most at risk and why, based on available telemetry and configuration review)
  • Gap analysis mapped to Purview data security solutions and operational processes
  • Prioritised remediation backlog (quick wins + strategic controls) with sequencing and dependencies
  • Target operating model recommendations: ownership, exception governance, review cadence, and evidence expectations
  • Implementation roadmap (phased) aligned to business outcomes and user experience impact

How It Works

  1. Discovery and scope - confirm data locations, business priorities, in-scope workloads, and licensing constraints.
  2. Baseline - review current configuration and governance; identify data risk themes and control gaps.
  3. Policy and workflow validation - validate how DLP/label policies behave for real use cases and how alerts/incidents are triaged and investigated.
  4. Roadmap and backlog - define quick wins, strategic controls, and sequencing (including change management considerations).
  5. Readout - stakeholder readout, Q&A, and agreement on next steps (implementation optional).

Engagement Options

  • Assessment Only - data risk baseline and roadmap without implementation
  • Assessment + Quick Wins - assessment with delivery of agreed low-risk improvements
  • Extended Assessment - deeper focus on insider risk and investigation workflows
  • Follow-On Delivery - phased implementation of the agreed remediation backlog
