DataStealth Data Discovery is a data discovery tool that scans enterprise environments to locate sensitive data across structured and unstructured sources, including on-premise systems, cloud storage, shadow IT, and third-party SaaS applications. The tool identifies PII, PHI, and PCI data within databases, file shares, data lakes, logs, PDFs, scans, ZIPs, and nested or embedded content. Each finding is enriched with contextual metadata such as system, owner, location, and data residency information. Results are consolidated into a unified report that maps discovered data by location and sensitivity level, producing a risk profile and actionable inventory. Discovery scans can be run on-demand or on a scheduled basis to maintain a continuously updated data inventory. Deployment requires only a DNS update and does not require agents or code changes. The tool is designed to surface hidden repositories and unsanctioned applications that may not appear in existing IT asset registries. Findings from Data Discovery can be fed directly into DataStealth's broader Data Security Platform to apply tokenization, masking, or encryption to discovered sensitive data. The platform is positioned to support compliance with PCI DSS, HIPAA, and GDPR requirements by providing verifiable discovery reports.
