Sensitive Data Discovery for Data Lakes
Uncover Hidden PII/PHI Across Your Data Lake
Modern data lakes are more than tables — they contain documents, logs, code, and AI training data. Protecto’s DeepSight scans every corner of your lake to find PII, PHI, and secrets — even in messy formats, typos, and mixed languages that legacy tools miss.
Why Protecto Wins — Others Can’t
Discover hidden sensitive data without losing context—scan structured data, unstructured documents, logs, and complex formats while keeping data utility intact.
AI-Powered Discovery
Finds PII, PHI, PCI, and secrets across structured and unstructured formats
Scans All Data Types
JSON, logs, free text, markdown, code repositories, tickets, and more
Context-Aware Detection
Goes beyond patterns to detect sensitive data in context and identify compound risks
“With Protecto’s scanning, we uncovered sensitive data hidden across 50 million records that other tools completely missed.”

Hidden Risks in Data Lakes
Data lakes on modern platforms like Databricks, Snowflake, and S3 don’t just hold structured tables. They contain all types of data used for analytics, operations, and AI — creating massive blind spots for sensitive information:
- Large Volumes — customer records, transaction logs, clinical data, and CRM exports, often spread across multiple business units
- Log Files — application logs, system logs, and audit trails often containing personal data
- Complex Formats — JSON objects, markdown docs, semi-structured data, and code repositories
- AI Training Datasets — prompts, responses, embeddings, and intermediate files feeding machine learning
- 47% of enterprise cloud data is sensitive—including personal, financial, and health-related information
