# blurgate.legal > Privacy-first PII anonymization platform. Detect and redact personal information in text and documents with enterprise-grade security on ISO 27001-certified German servers. ## About blurgate.legal is an enterprise-grade platform for detecting and anonymizing personally identifiable information (PII) in text, documents, and images. Built with a zero-knowledge architecture, all data is encrypted client-side before reaching the server — administrators cannot access user data. The platform runs on ISO 27001-certified German servers and is fully GDPR compliant. ### Key Capabilities - **PII Detection**: AI-powered recognition of 50+ entity types including names, addresses, phone numbers, emails, IBANs, social security numbers, medical record numbers, and more - **Anonymization Methods**: Multiple strategies including redaction (blackout), masking (partial hide), hashing (one-way), encryption (reversible), replacement (synthetic data), and custom patterns - **Multi-Language**: Supports 48 languages using spaCy (25 languages), Stanza (7 languages), and XLM-RoBERTa transformer models (16 languages) - **Document Formats**: Plain text, PDF, DOCX, XLSX, CSV, images (JPG, PNG, TIFF via OCR) - **Zero-Knowledge Architecture**: Client-side encryption with HKDF key derivation; server never sees plaintext data - **Batch Processing**: Upload and process multiple files simultaneously with progress tracking - **Presets**: Save and reuse anonymization configurations for consistent processing ### Integration Options - **REST API**: Full-featured API for automated workflows, CI/CD pipelines, and custom integrations - **Office Add-in**: Native Microsoft Word and Office integration for in-document anonymization - **Desktop App**: Standalone application for offline processing without internet dependency - **Chrome Extension**: Browser-based anonymization for web content and form data - **MCP Server**: Model Context Protocol server enabling AI agents (Claude, GPT, etc.) to use anonymization as a tool ### Technical Details - **Backend**: Python-based Presidio framework with custom NER models - **NLP Pipeline**: Tesseract OCR → spaCy/Stanza/Transformers → Presidio Analyzer → Presidio Anonymizer - **Encryption**: AES-256-GCM with HKDF-derived keys, Shamir secret sharing for key recovery - **Infrastructure**: Hetzner Cloud (Germany), ISO 27001 certified, daily encrypted backups - **Authentication**: Email/password with TOTP-based two-factor authentication --- ## Features ### PII Detection URL: https://blurgate.legal/features/pii-detection AI-powered detection of 50+ entity types across 48 languages. Uses a multi-model NLP pipeline combining spaCy, Stanza, and XLM-RoBERTa transformer models for maximum accuracy. Supports custom entity recognizers and regex patterns. ### Anonymization Methods URL: https://blurgate.legal/features/anonymization-methods Multiple anonymization strategies: redact (replace with entity label), mask (partial character replacement), hash (SHA-256 one-way), encrypt (AES-256 reversible), replace (synthetic data generation), and custom regex-based transformations. ### Multi-Language Support URL: https://blurgate.legal/features/multi-language 48 languages supported with varying NER accuracy tiers. Tier 1 (best): English, German, Spanish, French, Italian, Portuguese, Dutch, Polish, Russian, Japanese, Chinese, Korean, Arabic, Hindi, Turkish. Automatic language detection with manual override. ### Office Add-in URL: https://blurgate.legal/features/office-addin Microsoft Office integration allowing users to anonymize text directly within Word, Excel, and PowerPoint. Side panel UI for entity selection and method configuration. ### API Access URL: https://blurgate.legal/features/api RESTful API with JSON request/response format. Endpoints for text analysis, anonymization, batch processing, and entity management. API key authentication with rate limiting. ### Batch Processing URL: https://blurgate.legal/features/batch-processing Upload multiple documents for simultaneous processing. Supports ZIP archives. Progress tracking with per-file status. Results downloadable as ZIP with anonymized versions. ### Image Anonymization URL: https://blurgate.legal/features/image-anonymization OCR-based PII detection in images. Tesseract OCR extracts text, Presidio analyzer identifies entities, and bounding boxes are used to redact PII regions in the original image. ### Desktop App URL: https://blurgate.legal/features/desktop-app Native desktop application for Windows, macOS, and Linux. Supports offline processing for air-gapped environments. Local processing with optional cloud sync. ### Chrome Extension URL: https://blurgate.legal/features/chrome-extension Manifest V3 Chrome extension for anonymizing text on web pages, in forms, and in email clients. Right-click context menu integration. ### Zero-Knowledge Architecture URL: https://blurgate.legal/features/zero-knowledge All user data is encrypted client-side using AES-256-GCM with HKDF-derived keys before transmission. The server stores only encrypted blobs. Key recovery via Shamir secret sharing. Administrators cannot access user data. ### MCP Server URL: https://blurgate.legal/features/mcp-server Model Context Protocol server that exposes anonymization as tools for AI agents. Enables Claude, GPT, and other LLMs to detect and redact PII as part of agentic workflows. --- ## Use Cases ### Enterprise URL: https://blurgate.legal/use-cases/enterprise Large-scale PII anonymization for organizations handling sensitive customer data.
