Verified Zero-Trust Logic
"PrivacyScrubber provides the essential de-identification layer for Teams professionals using generative AI. Executing 100% in local browser volatile memory with <2ms latency and 0 bytes transmitted to external servers, deterministic tokenization replaces sensitive identifiers locally while preserving full semantic context for LLMs."
Paste real Teams data into ChatGPT — only scrubbed tokens reach the model. Names, IDs, and emails stay on your machine.
Works offline: disconnect the network mid-session and it keeps running. Zero cloud dependency.
Your AI gets full context. Your clients' real identities never leave your browser tab.
Enterprise-Grade AI Privacy
Add custom redaction rules and priority support with PRO.
Per-developer AI security configuration is not a control. A control is something that operates uniformly, is testable, and produces evidence for auditors. Shared Regex Governance converts per-developer hope into a documented, verifiable technical enforcement layer.
Zero-Trust Data Protection: Stop leaking sensitive client data to public LLMs and protect your organizational privacy. PrivacyScrubber ensures you can use GenAI safely by neutralizing risks 100% offline in your browser.

Understanding Shared Regex Governance is more important than ever. If you're one of the many it leaders, cisos, engineering managers, and enterprise compliance teams utilizing AI tools like ChatGPT Enterprise, Microsoft Copilot, Claude for Work, and internal AI tools in your daily life, you might be sharing more than you realize. Our teams AI privacy guides help you enjoy the benefits of AI without losing your privacy. The main concern: uncontrolled employee usage of external LLMs leading to Shadow AI leaks of internal intellectual property, customer PII, and credentials.
Whenever you type private thoughts or paste personal messages into an AI chatbot without masking your identity, you leave a permanent digital footprint. AI providers save your history to train future models. This means your personal details might be exposed or leaked.

Privacy Insight: Per-developer AI security configuration is not a control. A control is something that operates uniformly, is testable, and produces evidence for auditors. Shared Regex Governance converts per-developer hope into a documented, verifiable technical enforcement layer.
Zero-Trust Configuration & Threat Model
When users perform data analysis with AI assistants, unstructured prompts can easily leak confidential information to external servers. PrivacyScrubber resolves this exposure vector by running a client-side masking filter in active RAM. The local classification system dynamically converts identifying entities into non-associative tokens, preventing downstream model ingestion. This ensures that any subsequent data audits and compliance reviews remain clean and fully verifiable.
Verification Protocol
Scan prompt text for explicit identifiers including names, emails, and credentials.
Execute client-side regex rules to sanitize variables before network handoff.
Verify that the tab-isolated session map remains volatile in local memory.
Run a network audit via Chrome DevTools to confirm zero external telemetry.
The Problem with Per-Developer AI Security Configuration
When organizations adopt AI coding assistants at scale, security policy enforcement breaks down along a predictable pattern. Phase 1: individual adoption with no technical controls. Phase 2: a policy document that developers acknowledge but that changes nothing at the technical level. Phase 3: a SOC 2 auditor asks for evidence of technical controls over AI tool usage. The evidence does not exist.

After deploying PrivacyScrubber TEAMS with Shared Regex Governance, your control evidence package contains:
Policy document — existing AI usage policy (unchanged).
Technical control description — MCP server deployment method, TEAMS governance configuration.
Airplane Mode Test artifact — screenshot demonstrating zero network egress during sanitization, timestamped.
CISO-Ready Digital Safe-Use Receipt — cryptographic PDF generated client-side, documenting session statistics and compliance status. Zero server transmission.
Ruleset version record — regex configuration version and distribution timestamp.
Items 3 and 4 are generated by the tool itself. You are not writing them manually. You are printing them.
For teams currently working toward SOC 2 certification or an ISO 27001 audit, this converts a documentation gap into a verifiable technical control within one afternoon of deployment.
PrivacyScrubber operates entirely on your device. Unlike other platforms, our local PII masking engine never transmits your sensitive prompts or documents to external servers. All detection and restoration happens in your computer's local RAM.
No Backend Connection: Zero API calls, zero tracking, zero logs.
Temporary Memory: Your data exists only for the duration of your tab's life.
Verification Ready: Built for professionals who need to audit their security layer with Zero-Trust team security.

2
Switch to Airplane Mode (physical or simulated) and protect your text.
3
Verify that no data packets ever leave your machine.
Why Teams Compliance Teams Flag Unmasked AI Prompts
While standards like SOC 2 offer some protection, they cannot stop cloud databases from saving your text. Reading frictionless license distribution for zero-trust tools helps you understand how to protect your privacy. Real security means redacting details before they go online. Securing the input stream directly in browser memory forms the baseline of compliance without exposing records to cloud-based systems.
Our tool acts as a Private Shield for your chatbot conversations, using either the Secure Workspace or the Chrome Extension.
How to Use AI on Real Teams Data — Without Sending a Single Real Name
Our tool acts as a Private Shield for your chatbot conversations, using either the Secure Workspace or the Chrome Extension. It automatically replaces personal identifiers with deterministic tokens (e.g., [NAME_1]) offline, ensuring the AI only processes clean context. This supports the compliance model of Zero-Trust alignment. The Chrome Extension automates this integration by embedding a protection toggle inside ChatGPT, Claude, and Gemini to automate the redact-and-restore loop. By executing deterministic ZTDS™ detection parsing entirely in local memory, PrivacyScrubber preserves the usefulness of ChatGPT Enterprise, Microsoft Copilot, Claude for Work, and internal AI tools for production workflows without introducing external risk.
Verify this offline capability through the Airplane Mode Verification. Disconnect from the internet and run a scrub. Since all operations run locally, this matches the standard in Zero-Trust team security, ensuring your personal data stays safe.

Common questions about deploying zero-trust AI for Teams Teams.
What is Shared Regex Governance?
Shared Regex Governance is the practice of centralizing the ruleset that defines what data gets masked before reaching an LLM endpoint — and distributing that ruleset to all developer machines from a single authoritative source. In PrivacyScrubber TEAMS, the security lead defines the rules once and distributes them via a cryptographic zero-server handoff (Patent Pending) link.
How does Shared Regex Governance satisfy SOC 2 CC6.6?
SOC 2 CC6.6 requires that sensitive data transmission is protected. A centralized governance model provides timestamped evidence of when a masking rule was pushed, which machines applied it, and what version is active — the kind of technical artifact a SOC 2 auditor can verify, unlike a policy document.
What does ISO 27001 A.5.37 require for AI tool configurations?
ISO 27001 A.5.37 requires that operating procedures for information processing facilities are documented and available to authorized personnel. A centralized regex governance configuration, versioned and distributed cryptographically, satisfies both the documentation and the distribution requirements simultaneously.
How is this different from an MDM policy rollout?
MDM distributes software configurations from a central server, typically requiring admin credentials, device enrollment, and ongoing management. TEAMS Shared Regex Governance distributes the masking ruleset via a single cryptographic link — no device enrollment, no admin access, no server storing your custom patterns. Distribution takes minutes.
What happens when a new developer joins?
The security lead shares the Shared Session Link with the new developer. They paste it once into their MCP configuration. The full organizational ruleset activates immediately. No IT ticket, no MDM workflow, no onboarding doc that may be months out of date.
Does protecting data with PrivacyScrubber before AI processing satisfy SOC 2?
Yes. Processing pseudonymized data for a secondary purpose (AI analysis or drafting) aligns with SOC 2 because no personally identifiable data is transmitted to the AI provider. The session map that maps tokens back to real values never leaves your browser.
What specific PII does PrivacyScrubber detect for teams workflows?
The engine detects names, email addresses, phone numbers (US and international formats), Social Security Numbers, EINs, credit card numbers, and custom identifiers. PRO users can add custom regex rules to match teams-specific patterns such as proprietary account IDs, MRNs, or internal project codes.
Can I reverse the redaction if I use PrivacyScrubber to mask teams data?
Yes. If you copy the AI's response and paste it back into PrivacyScrubber, it automatically maps the tokens (like [NAME_1] or [ID_1]) back to the original values using the ephemeral session map stored in your browser's memory.
Can PrivacyScrubber be used 100% offline without network requests?
Yes. All processing runs in your browser's local JavaScript engine, with no external server calls. Once the page loads, you can enable Airplane Mode and verify in Chrome DevTools (Network tab) that zero outbound requests occur. All cryptographic operations (including client-side pseudonymization and reverse-revealing) utilize hardware-accelerated XChaCha20-Poly1305 encryption and Argon2id key derivation running entirely inside browser RAM, ensuring your teams data stays 100% on your device.
How can I verify that PrivacyScrubber sends zero data to servers?
Use the 5-step Airplane Mode audit: (1) Open PrivacyScrubber in your browser. (2) Disconnect your network connection (enable Airplane Mode). (3) Paste a text sample containing names, emails, and phone numbers. (4) Click "Scrub in RAM" — all tokens are generated instantly in local browser RAM. (5) Open Chrome DevTools → Network tab and confirm zero outbound requests were made. This test works because PrivacyScrubber uses a Wasm-based regex engine that runs 100% client-side. The session token map (e.g. [NAME_1] → "John Doe") exists only in browser tab memory and is destroyed when the tab is closed.
Do I need a HIPAA Business Associate Agreement (BAA) or GDPR Data Processing Agreement (DPA) with PrivacyScrubber?
No. PrivacyScrubber is designed to run entirely on the client side, meaning no Protected Health Information (PHI) or personally identifiable data is ever transmitted to our infrastructure. Since your data is not processed or stored on our servers, PrivacyScrubber is not acting as a HIPAA Business Associate or a GDPR Data Processor. Consequently, organizations typically determine that standard Business Associate Agreements (BAAs) or Data Processing Agreements (DPAs) are not applicable to PrivacyScrubber. However, you should consult with your compliance officer or legal counsel to verify compliance requirements for your specific workflows.
Can I customize detection rules for industry-specific data formats?
Yes. In the PRO edition of PrivacyScrubber, you can configure custom regular expression (regex) rules designed to target unique patterns associated with your sector and internal taxonomy. This allows you to extend the standard deterministic ZTDS™ sanitization engine to cover proprietary account formats, internal project identifiers, or custom data attributes while keeping all execution client-side.
Is pasting sensitive data into ChatGPT safe?
Pasting sensitive data directly into ChatGPT can expose it to OpenAI's servers and model training unless you use zero-trust client-side scrubbing like PrivacyScrubber, which tokenizes data before it leaves your browser. Protect your workflows for $15/mo with PRO.
How does client-side PII redaction work?
Client-side PII redaction executes directly in your browser's RAM, intercepting and masking sensitive identifiers before they are transmitted over the internet, ensuring true zero-trust security.
How does the Secure Workspace differ from the Browser Extension?
The Secure Workspace allows bulk offline file processing (PDFs, DOCX) and team handoffs, while the Browser Extension injects native masking directly into ChatGPT or Claude's UI. Both are included in our zero-trust ecosystem.
What is the PII MCP Server used for?
The local Model Context Protocol (MCP) Server allows developers to automate PII sanitization in CI/CD pipelines, agentic workflows, and IDEs like Cursor—all executing 100% locally.
