Prism Investigator is the first (※1) fully autonomous investigation platform among DCGA vendors evaluated by Gartner, designed to accelerate compliance and legal investigations.
This data-source-agnostic AI platform reconstructs events by correlating communication data with business records, providing explainable case narratives that stand up to legal and regulatory requirements.
Designed for organizations with high regulatory demands, Prism Investigator reduces investigation time from weeks to minutes through its agentic AI workflow.
Sunnyvale, California – May 6, 2026 – Proofpoint, a leading cybersecurity and compliance company, today announced Proofpoint Prism Investigator (patent pending), a groundbreaking new investigation solution as part of its Digital Communication Governance (DCG) portfolio. Designed for organizations with high regulatory demands and litigation risk, Proofpoint Prism Investigator transforms traditional fragmented, manual investigations into an AI-driven, data-source-agnostic workflow. This enables the reconstruction of events across human and AI activities, revealing the context of risks, and compiling legally and regulatorily defensible case narratives in minutes, a process that previously took weeks. This marks a significant shift from search-centric investigations to autonomous event reconstruction. Prism Investigator is the first fully autonomous investigation platform among vendors evaluated in Gartner's Magic Quadrant for Digital Communication Governance and Archiving Solutions (※2).
As regulatory oversight intensifies and communication data is widely dispersed across collaboration tools, archives, mobile channels, and business systems, the burden on compliance and legal departments is increasing. According to CUBE's "2025 Cost of Compliance" report, approximately two-thirds of companies anticipate an increase in compliance costs over the next year, and AI governance and ethics are cited as one of the key challenges organizations will face in 2026. In this context, traditional investigation methods relying on exports, keyword searches, and manual interpretation are no longer sustainable.
Harry Labana, Senior Vice President and General Manager of Proofpoint's Digital Communication Governance (DCG) business unit, stated: "Our customers demand faster responses while maintaining accuracy and fulfilling legal and regulatory accountability. Prism Investigator replaces fragmented, manual investigations with autonomous, explainable AI, reconstructing what happened, why it matters, and who was involved. This allows investigation teams to move from evidence collection to understanding the situation more quickly and confidently."
The three core innovations of Prism Investigator are:
・Data-Source Agnostic Architecture
Designed to integrate both structured and unstructured data within a single investigation workflow. Without requiring content export or re-ingestion, Prism Investigator connects to Microsoft 365 communication data, archives, and business records. This allows it to correlate human and AI-generated messages with contextual signals such as transaction data, logs, and other system activities, reconstructing events across multiple systems.
・End-to-End Autonomy
Powered by Proofpoint's Nuclei technology and Human Communications Agents, Prism Investigator goes beyond merely presenting data. It infers from communications and related records, identifies patterns, reconstructs timelines, and generates comprehensive case summaries through natural language workflows.
・Designed for Explainability and Defensibility
Prism Investigator generates transparent summaries and provides a complete audit trail of investigator inputs and AI inference processes.
