  • Diagnose labeling failures and misclassification, identify files that did not receive an intended label, and remediate the cause.
  
  
  • Validate classifier and label accuracy through structured spot checking with data owners, and tune detection logic on the results.
  
  
  • Apply sensitivity classification across firm content using sensitive information types, trainable classifiers, document fingerprints, exact data match, and SharePoint document metadata and managed properties.

• Maintain DLP policy documentation, exception logs, and change records to audit standard.


• Tune Insider Risk Management policies, including data theft by departing users, and maintain priority user and priority content scoping.


• Operate a repeatable departing employee activity lookback process and produce the review output Cybersecurity, Legal, and HR act on.


• Investigate alerts to root cause and determine whether an alert reflects real user activity or a detection that needs tuning.


• Records, Retention, and Data Discovery
  
  
  
  • Maintain retention labels, retention policies, auto apply rules, and disposition review, and evidence that data destruction completes as the retention schedule requires.
  
  
  • Administer Content Explorer, Activity Explorer, and Purview Audit to evidence label application, data movement, and retention outcomes.
  
  
  • Run content search and eDiscovery queries to answer internal data questions, quantify sensitive data exposure, and support Cybersecurity investigations.
  
  


• Platform Operations and Automation
  
  
  
  • Automate policy deployment, configuration export, and recurring reporting with PowerShell and the Microsoft Graph API.
  
  
  • Troubleshoot tenant, licensing, admin role, and client side issues that block Purview functionality, with the IT infrastructure and identity teams.
  
  
  • Coordinate user acceptance testing with internal testers before policy or label changes reach production, and track test completion to closure.
