Zero-Trust Data Sanitization
Watch PrivacyScrubber's local engine transform sensitive Security data instantly in your browser, without any API calls.
Financial analysts, wealth managers, and tax accountants leverage LLMs to analyze earnings reports, audit general ledgers, and reconcile complex AP invoices. PrivacyScrubber's Finance Extension ensures that Social Security Numbers (SSNs), bank routing codes, corporate tax IDs (EINs), and confidential client balances are sanitized in local memory before prompt transmission.
Numerical Preservation & GL Accounting Tokenization
Financial analysis requires preserving numerical wages, decimal quantities, currency amounts, and tabular spreadsheet layouts while stripping personal names and account numbers. Our financial profile preserves line-item math with 100% precision.
Native Banking DLP for Wealth Management & Tax Workflows
Legacy cloud DLP proxies inspect traffic by decrypting corporate SSL streams, introducing 250ms+ latency and creating a secondary honeypot of plaintext financial records. PrivacyScrubber executes 100% within the browser's V8 sandbox, inspecting input fields in under 2ms. When tax documents (W-2s, 1099s, Schedule K-1s) are pasted into ChatGPT, the extension swaps sensitive taxpayer names with [TAXPAYER_1] while leaving wage brackets, withholding amounts, and deductions untouched.
Corporate AP Invoice & Tax Rehydration Workflow
-
1
Copy or Paste Unsanitized Content: Accountant pastes raw vendor invoice table containing vendor corporate names, bank IBAN, routing numbers, and invoice line items.
-
2
Real-Time In-Browser Sanitization: The extension identifies vendor names and routing codes, replacing them with [VENDOR_1] and [ROUTING_1] in local RAM.
-
3
Submit to LLM with Zero Cloud Exposure: Accountant asks ChatGPT: "Calculate blended tax liability and categorize GL expenses for [VENDOR_1]". OpenAI computes calculations perfectly.
-
4
Instant Local Reversal (Contextual Reveal): Accountant clicks Reveal in the floating popover to restore vendor names and invoice references for immediate posting into the ERP.
GLBA, SOX & FINRA Regulatory Alignment
Under Gramm-Leach-Bliley Act (GLBA) and SEC data protection mandates, financial institutions face severe penalties for unauthorized disclosure of Non-Public Personal Information (NPI). Local edge sanitization eliminates the need for third-party cloud data processing agreements, aligning directly with our Finance AI Security framework.
Spreadsheet Batch Sanitization & True Sync
When managing multi-client tax batches, analysts can toggle between the Chrome Extension in-page shield and the Web App bulk CSV/Excel engine. With True Sync architecture, custom regex rules for proprietary ledger codes synchronize instantly between the web hub and browser tabs, mirroring protocols in financial data privacy in AI and cleaning CSV financial data.
Verifiable Zero-Cloud Transmission Audits
Financial compliance teams can verify that zero NPI left the local endpoint by reviewing the browser network waterfall. This radical transparency satisfies SOC 2 for AI requirements for internal bank risk assessments.
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.
