The ideal candidate is analytical, curious, and comfortable translating security data into clear findings and practical control improvements.

• Monitor, triage, investigate, and respond to DLP, insider risk, and endpoint security alerts and incidents.

• Support DLP controls across Exchange, SharePoint, One Drive, Teams, endpoints, browsers, removable media, printing, clipboard activity, and cloud applications, as applicable.
• Review false positives, false negatives, user overrides, and recurring alert patterns; recommend and implement policy improvements.
• Support Microsoft Purview Insider Risk Management use cases, indicators, policies, alerts, cases, and privacy-aware investigation workflows.
• Partner with identity, corporate security, human resources, incident response teams, and line-of-business teams during investigations, containment, remediation, and control changes.
• Use Microsoft Purview, Microsoft Defender, Sentinel One EDR, Splunk SIEM, audit, identity, and endpoint telemetry to build investigation timelines, correlate activity, and validate findings.
• Create dashboards, metrics, and trend analyses that communicate incident volume, policy effectiveness, data movement, root causes, and control gaps.
• Develop and maintain procedures, investigation playbooks, tuning standards, exception records, and knowledge articles.
• Participate in testing, change management, and phased deployment of new or updated data protection controls.
• Identify opportunities for automation, enrichment, and workflow integration that improve response speed and consistency.

• Experience in information security, data protection, security operations, incident response, threat analysis, compliance operations, criminology, law enforcement, corporate security, fraud investigation, or a related discipline. Candidates with transferable investigative experience are encouraged to apply.
• Working knowledge of DLP concepts, data classification, sensitive data handling, insider risk, and common data exfiltration paths.
