PrivacyScrubber

PrivacyScrubber is a 100% client-side, zero-trust PII sanitization and data masking platform for Generative AI workflows. It protects sensitive enterprise, legal, financial, and patient data before it ever reaches ChatGPT, Claude, Microsoft Copilot, Google Gemini, or internal LLMs. Unlike traditional cloud DLP proxies that intercept and store your confidential data on third-party servers, PrivacyScrubber executes entirely in your browser's local memory (RAM). Zero server calls. Zero data stored. Zero telemetry. Verified offline in Airplane Mode. HOW IT WORKS: 1. In-Place Sanitization: As you type in ChatGPT, Claude, or Copilot, the free Chrome Extension (or Web App) instantly replaces names, emails, phone numbers, national IDs, credit cards, IP addresses, and custom secrets with safe cryptographic tokens ([NAME_1], [EMAIL_1], [SECRET_1]). 2. Safe AI Processing: The LLM processes the sanitized prompt without learning confidential identities or trade secrets. 3. 1-Click Reverse Detokenization: When the AI responds, PrivacyScrubber automatically restores the original data locally in your browser memory — completely invisible to the AI provider. KEY CAPABILITIES: • Free Chrome Extension: Real-time prompt sanitization directly inside ChatGPT, Claude, Gemini, and Copilot via hotkey (Alt+Shift+X) or automated scrubber button. • Multi-Format Document Redaction: Sanitize PDF, Word (.docx), Excel (.xlsx), CSV, and text files directly in browser memory without server uploads. • Offline OCR Engine: Extracts and sanitizes scanned contracts, medical records, and receipts in local RAM without external cloud vision APIs. • 25 Specialized Industry Profiles: Pre-configured detection for HIPAA Safe Harbor (healthcare), Attorney-Client Privilege (legal), PCI DSS & GLBA (banking), Blind HR screening, and DevOps secrets (API keys, JWTs). • Cryptographic CISO & DPO Audit Receipts: Downloadable PDF compliance certificates with SHA-256 integrity proofs and regulatory defense mappings. • Zero-Server Team Session Handoff: Teams share sanitized prompts and restore tokens across colleagues using end-to-end client-side encryption (Argon2id + XChaCha20-Poly1305). • Developer SDK (@privacyscrubber/sdk): Headless Node.js and WebAssembly (WASM) engine with <1ms in-memory latency and zero network egress for backend pipelines and RAG architectures. SECURITY & COMPLIANCE (ZERO-DPA ARCHITECTURE): Because data never leaves the client device, PrivacyScrubber eliminates the need for Data Processing Agreements (DPAs) under GDPR Article 28 and satisfies HIPAA Safe Harbor (§ 164.514), SOC 2 Type II exemption, and ISO 27001 A.8.11 data masking requirements. Backed by academic research published on CERN/Zenodo (DOI: 10.5281/zenodo.22058770) and OSF. TRANSPARENT PRICING TIERS: • Free: $0 forever.

IRI DarkShield

IRI DarkShield: Data Masking and PII Discovery for Structured, Semi-Structured, and Unstructured Data IRI DarkShield is self-hosted data masking and sensitive-data discovery software that helps organizations find, classify, de-identify, redact, encrypt, pseudonymize, and audit Personally Identifiable Information (PII) and other sensitive data—even when that data is hidden in unstructured and semi-structured sources. Unlike traditional data masking tools designed primarily for database columns, IRI DarkShield is built to protect the “dark data” that can be difficult to discover and secure: free-form text, documents, PDFs, images, logs, JSON/XML, healthcare files, NoSQL databases, relational databases, and other data repositories across on-premises and cloud-controlled environments. If you are asking, “How can I find PII in unstructured data?”, “How do I mask sensitive information in PDFs and documents?”, “What data masking tool supports NoSQL and unstructured data?”, or “How can I automate PII discovery and data anonymization across multiple data sources?”, IRI DarkShield is designed to address these challenges. Discover Hidden PII and Sensitive Data DarkShield combines data classification, automated discovery, search, extraction, and masking capabilities in one solution. Organizations can define reusable data classes and search rules to locate sensitive information across disparate data sources and then apply consistent protection policies. DarkShield supports multiple discovery techniques, including regular expression and pattern matching, exact and fuzzy dictionary or lookup matching, data-path and column filters, AI-enabled relational database classification, and handwriting recognition, machine-learning-assisted Named Entity Recognition (NER), facial and signature detection, image-region and bounding-box detection, and metadata and content-based matching. This makes DarkShield useful for discovering names, addresses, email addresses, phone numbers, identification numbers, financial information, healthcare information, and other forms of PII, PHI, confidential information, and sensitive business data. Mask Unstructured, Semi-Structured, and Structured Data DarkShield provides a broad range of data masking and data anonymization techniques, allowing organizations to select the appropriate protection method for each sensitive data class and use case. Available masking functions include redaction and obfuscation, encryption and format-preserving encryption, pseudonymization, hashing, encoding, randomization, scrambling, string and bit manipulation, fabrication and synthesis, blurring, and deletion. Deterministic masking can be used where consistent replacements are important for maintaining data relationships and usability across systems. Protect Data Across Many Formats and Repositories DarkShield is designed for environments where sensitive information exists beyond conventional database tables. Supported sources and formats include relational databases and .SQL files, NoSQL databases, free-form text and log files, JSON and XML, CSV and other flat files, Microsoft Word, Excel, and PowerPoint documents, PDF documents including documents containing images, Parquet and other data formats, HL7, X12, FHIR, and other healthcare/EDI data, DICOM medical studies, image files, audio, signatures and PII in handwriting), and cloud and network repositories. DarkShield can search data on-premises, across network file systems, and in cloud storage environments such as Amazon S3, Microsoft Azure Blob Storage, Google Cloud Storage, OneDrive, and SharePoint Online. Data Privacy, Compliance, and Risk Reduction Sensitive data discovery and masking can help organizations reduce the exposure of PII and other regulated information while supporting privacy and security initiatives. Common use cases include GDPR data protection and “Right to Be Forgotten” workflows, data portability and data-access requests, HIPAA and PHI de-identification, PCI DSS and payment-data protection, privacy compliance and data governance, data breach risk reduction, secure data sharing with vendors and partners, development and test-data masking, analytics and AI/ML data de-identification, data migration and application modernization, secure log and document handling, and eDiscovery and sensitive-data identification. DarkShield can generate search and masking results with associated metadata for auditing, reporting, investigation, and compliance workflows. Automate Data Masking With GUI, CLI, and API DarkShield provides options for both technical and non-technical users. Data discovery and masking jobs can be designed through a desktop or web UI, and executed through the GUI, command line, or API. You can automate recurring data masking operations, integrate DarkShield into existing workflows, and schedule jobs to process new or modified files. The DarkShield API can also be used to embed PII discovery and data masking into applications, data pipelines, DevOps processes, and enterprise data management workflows. Self-Hosted Data Protection IRI DarkShield is designed with a self-hosted architecture that gives organizations control over where their data is processed. It runs on-premises by default and can also be deployed in controlled container or cloud-VM environments. This approach is particularly useful for organizations with strict data-sovereignty, privacy, security, or regulatory requirements that prefer not to send sensitive source data to an external SaaS masking service. Consistent Data Masking Across the Enterprise DarkShield shares data classes and masking functions with other IRI data-protection technologies, including IRI FieldShield. This supports consistent policies for protecting sensitive data across structured databases, files, documents, and other repositories. DarkShield can also be used standalone or as part of the broader IRI Voracity data-management platform, providing organizations with options to combine data discovery, integration (including textual ETL), transformation, migration, masking, and test-data generation workflows. Who Uses IRI DarkShield? IRI DarkShield is designed for organizations that need to discover and protect sensitive information across complex, heterogeneous data environments, including: *Data security and privacy teams *Data governance and compliance teams *Database administrators and data engineers *IT and information security teams *DevOps and application-development teams *Healthcare organizations *AI / ML engineers *Financial services organizations *Government agencies *Enterprises managing large document and file repositories Why Choose IRI DarkShield? IRI DarkShield extends data masking beyond conventional database columns to help organizations protect sensitive information wherever it exists. Its combination of PII discovery, data classification, AI/ML-assisted search, unstructured data masking, document redaction, NoSQL masking, database masking, encryption, pseudonymization, automation, API integration, and self-hosted deployment makes it a flexible option for enterprise data privacy and de-identification programs. In short, IRI DarkShield helps organizations answer one of the hardest questions in data security: “Where is our sensitive data?” It then provides the tools to find it, understand it, mask it, and demonstrate that it has been protected.
