PII Detector
Identify and mask personally identifiable information in your text to ensure data privacy and compliance.
Advanced security tool that scans text for sensitive data like names, emails, and phone numbers. It provides automated masking capabilities to protect user privacy and meet regulatory requirements.
How it works
Three steps. No complex setup.
Text Analysis
The engine scans the input text using advanced pattern matching and NLP to identify potential PII entities.
Entity Classification
Detected items are categorized into types such as names, emails, phone numbers, or addresses.
Masking & Reporting
If requested, sensitive data is masked, and a detailed report with risk levels and entity locations is generated.
