• Configure Purview sensitive info types, trainable classifiers, and exact data match.
• Run data estate scans across M365, endpoints, and file shares.

2. Sensitivity Labelling

• Deploy and tune manual and auto-labelling across Exchange, SharePoint, OneDrive, Teams, and endpoints.
• Maintain label taxonomy, scopes, encryption settings, and downgrade rules.
• Drive adoption with business units; track coverage, accuracy, and mis-labelling.

3. DLP Engineering and Maintenance

• Design, deploy, and tune Purview DLP across email, collaboration, endpoints, and browsers.

• Manage policy lifecycle and documented exceptions; keep configuration and change records current.

4. Leak Monitoring, Investigation, and Remediation

• Monitor DLP, Insider Risk, and Netskope telemetry for data leakage and anomalous data movement.
• Triage and investigate alerts across email, endpoint, cloud, removable media, and printing to closure.
• Proactively identify leak paths — shadow IT, over-shared links, guest access, unmanaged devices, coverage gaps.
• Analyze trends to pinpoint recurring leak sources, high-risk users, and exposed data sets.
• Recommend and implement fixes: policy changes, rule tuning, labelling, access restrictions, app controls, user coaching.
• Run content search and eDiscovery; preserve evidence, escalate confirmed exfiltration per IR runbook with the managed SOC.

Secondary — Cybersecurity GRC

• Maintain control matrices and cross-framework mapping.

8. Control Monitoring

• Perform periodic checks on access reviews, policy attestations, training completion, exceptions, and vendor compliance.
• Escalate control gaps and overdue actions to relevant stakeholders.

9. Third-Party Risk

• Support awareness campaigns, policy communication, and data handling guidance for business users.
• Produce monthly labelling, DLP, and risk metrics; prepare management and committee reporting.
• Maintain accurate governance and compliance records.
