Zero-Trust Data Sanitization vs All 4 Competitor Paradigms

Most data masking solutions were designed for static databases or cloud networks. Generative AI requires interactive, bidirectional tokenization directly at the user's cursor.

Verification Standards

The 5-Step CISO Zero-Trust Audit Procedure

Don't take vendor security claims on faith. Use this 5-step technical procedure to independently verify that zero data leaves employee workstations.

01

Network Egress Inspection (DevTools Audit)

Open Chrome DevTools (F12) → Network tab. Filter by Fetch/XHR and paste a document containing names, emails, and SSNs. Trigger sanitization. Verify that 0 network requests are initiated during the entire de-identification lifecycle.

Result: Total bytes transmitted during PII scrubbing = 0 bytes.
02

Airplane Mode Hard-Cut Verification

Load PrivacyScrubber once, then disconnect Wi-Fi and Ethernet completely (Airplane Mode). Perform text sanitization, multi-page PDF OCR extraction, and regex rule matching. Every single capability executes at full speed without network connectivity.

Proof: Air-gapped WebAssembly engine runs autonomously inside the browser sandbox.
03

Tab-Isolated RAM Volatility Audit

Inspect localStorage and IndexedDB storage in DevTools Application tab. Confirm that session mappings are stored strictly in volatile JavaScript heap memory and are wiped unconditionally on tab reload or tab close.

Compliance: Satisfies GDPR Art. 17 (Right to Erasure) and SOC 2 Zero-Retention principles.
04

Bidirectional LLM Context Preservation

Unlike permanent redaction tools that destroy entity relationships, PrivacyScrubber swaps names into indexed tokens ([NAME_1], [ID_2]). The AI model reasons about organizational hierarchies without knowing actual identities, and 1-Click Reveal rehydrates the response locally.

Advantage: Eliminates AI hallucinations caused by black-box redactions.
05

Zero Sub-Processor Procurement Review

Review our Zero Sub-Processors Registry and download our Zero-DPA Procurement Legal Memorandum to bypass the standard 6-week vendor security questionnaire cycle.

Result: Instant procurement clearance for enterprise security teams.
Unlimited Corporate Safety

Enterprise AI Privacy Flat Rate

Stop paying per-seat fees. Deploy zero-trust data protection to your entire team for just $99/month flat. No server logs, no DPA setup bottlenecks, MDM-ready extension.

Frequently Asked Questions

Why choose local browser sanitization over cloud DLP APIs?

Cloud DLP APIs (like Google Cloud DLP or Nightfall AI) require transmitting unredacted, cleartext sensitive data across the public internet to third-party servers. This creates legal exposure under GDPR Article 28, mandates signed Business Associate Agreements (BAAs) under HIPAA, and adds 150ms–3,000ms of network latency. PrivacyScrubber performs 100% of detection and tokenization locally inside browser RAM using JavaScript and WebAssembly — zero bytes ever leave your device.

How does PrivacyScrubber avoid creating a data processor relationship under GDPR and HIPAA?

Because PrivacyScrubber processes all data client-side and never transmits prompts or document text to our servers, we never possess, store, or process your data. This means PrivacyScrubber is not a data processor under GDPR Article 28 and does not handle Protected Health Information (PHI) under HIPAA, allowing your organization to bypass multi-week DPA legal reviews and vendor risk assessments.

What is the difference between permanent redaction and reversible tokenization?

Permanent redaction replaces sensitive text with black boxes or generic strings like [REDACTED], which destroys semantic relationships and causes generative AI models (ChatGPT, Claude) to hallucinate or lose conversational context. PrivacyScrubber uses reversible tokenization: entities are mapped to indexed semantic tokens (e.g. [NAME_1], [FINANCIAL_2]) and restored with original identities locally upon receiving the AI's response via 1-Click Reveal.

Can PrivacyScrubber replace heavy enterprise DLP tools like Purview or Zscaler?

For Generative AI prompt security and web clipboard protection, yes. Enterprise security gateways and kernel-level DLP agents introduce substantial network latency, require complex MDM certificate rollouts, and carry expensive per-seat licensing fees. PrivacyScrubber provides instant, non-intrusive browser-native DLP that secures ChatGPT, Claude, and Gemini with zero server setup for a flat $99/month team rate.

Is there a free version of PrivacyScrubber available?

Yes. PrivacyScrubber Free includes full General PII profile sanitization (up to 15,000 characters per scrub), 5,000 character trial quotas for all 25 specialized industry profiles, single document scrubbing (.txt, .docx), and local reverse scrub. Upgrading to PRO or TEAMS unlocks unlimited volume, batch file processing, offline OCR/PDF sanitization, and team governance.
