Insider risk investigations demand business context, privacy‑by‑design, and HR/Legal due process. Traditional SOCs are optimized for external threats. Infotechtion's specialist practice correlates Purview signals, maintains defensible chain‑of‑custody, and feeds findings back into prevention.
From intake to resolution, a repeatable Target Operating Model for insider risk investigations with clear RACI, measurable KPIs, and audit‑ready evidence.
Intake from Microsoft Purview IRM, DLP events, and business escalations. De‑duplicate, correlate, and assign priority using business context and sensitivity labels.

SOCs are optimized for external threats and SIEM‑centric monitoring. Insider risk investigations demand business context, privacy‑by‑design, HR/Legal due process, and defensible case narratives. These are skills and workflows that differ fundamentally from incident response.
We maintain strict, process‑driven chain‑of‑custody supported by Purview audit logs, role separation, and documented evidence‑handling procedures. All artifacts are preserved with timestamps and access logs for regulator‑ready case packs.
We provide privacy‑preserving summaries and follow consultation steps required by local policy and collective agreements. Employee representatives are engaged via documented liaison processes where applicable.
Investigation findings are fed back into DLP/IRM policies, exceptions, user education, and Adaptive Protection. We track false positives/negatives, calibrate risk‑levels, and shorten time‑to‑containment with each release.
