Zero-Trust Data Sanitization
Watch PrivacyScrubber's local engine transform sensitive Security data instantly in your browser, without any API calls.
Chief Information Security Officers (CISOs) face an unprecedented challenge: employees across engineering, legal, HR, and finance are pasting proprietary company IP and regulated PII into generative AI models. PrivacyScrubber's CISO Governance Suite provides endpoint Zero-Trust DLP that blocks prompt exfiltration at the browser layer without costly server proxies.
Zero-Trust Data Sanitization (ZTDS) vs. Cloud Proxy Architecture
Legacy proxies decrypt SSL traffic on third-party cloud servers (adding 250ms+ latency and vendor risk). PrivacyScrubber executes 100% in endpoint browser RAM (<2ms latency).
Centralized Governance with Admin Blueprint Lock
Through the Teams Admin Hub, CISOs configure organization-wide custom regex rules (internal project codenames, customer IDs, proprietary data formats) and mandatory industry profiles. The CISO exports this policy as a cryptographically signed Blueprint (.psblueprint or URL hash). When employees import the blueprint into their Chrome Extension, rules display as [ENTERPRISE LOCKED] and cannot be modified or bypassed by staff.
Enterprise CISO Policy Enforcement Flow
-
1
Copy or Paste Unsanitized Content: CISO configures corporate DLP profile with mandatory rules for customer account IDs, internal project codenames, and API tokens.
-
2
Real-Time In-Browser Sanitization: CISO deploys signed Blueprint URL across all company Chrome browsers with Lock Rules enabled.
-
3
Submit to LLM with Zero Cloud Exposure: Employees use ChatGPT and Claude normally; the extension automatically redacts corporate identifiers in-place in <2ms.

Instant Local Reversal (Contextual Reveal): CISO generates client-side CISO Audit Receipts with local SHA-256 integrity hashes to present to SOC 2 and ISO 27001 external auditors.
ISO 27001 (A.8.11), SOC 2 (CC6.1) & NIST SP 800-53 Compliance
By enforcing client-side data masking before prompt transmission, PrivacyScrubber directly fulfills ISO 27001 Control A.8.11 (Data Masking) and SOC 2 CC6.1 without requiring secondary cloud DPAs, aligning with our AI Privacy Guides framework.
Cryptographic Team Session Handoff & Zero Cloud Storage
Colleagues can securely exchange sanitized prompt sessions using peer-to-peer client encryption (Argon2id + XChaCha20-Poly1305) without any central database, as detailed in PII protection basics and Zero-Trust AI frameworks.
Tamper-Evident CISO Audit Telemetry
Our SSOT telemetry engine calculates risk levels and framework triggers locally, producing downloadable audit receipts to satisfy GDPR/CCPA standards auditor mandates.
Latest Capabilities: Multi-Line Stitching & Local OCR
The PrivacyScrubber Chrome Extension features a smart 3-Line Name-Stitching Lookahead to capture names split across lines (e.g. Firstname
MiddleInitial
Surname) in scanned medical/clinical records, NDAs, and PDFs. It also supports Local Wasm OCR & PDF Sanitization to redact text from screenshots/PDFs offline, and Zero-Trust Session Sync (Argon2id + XChaCha20-Poly1305) to share rules peer-to-peer securely.
