Data Leak Prevention for Your Generative AI Workflows

Backed by Microsoft For Startups
Guided by Grayver Law Group
AES-256 Encryption
Free during early access

Data leak prevention for generative AI starts at the document level. Generative AI tools create enormous productivity gains, but they also introduce a new category of data leak risk. Every document uploaded to AI tools, or AI assistants is a potential leak vector. Automated PII redaction acts as a proven prevention layer, stripping names, SSNs, financials, and proprietary data from documents before they leave your organization.

Free and no sign-up required.

Key Takeaways

Generative AI tools are a growing source of accidental data leaks when employees upload unredacted sensitive documents.

Document-level PII redaction functions as an effective data leak prevention layer for all AI-assisted workflows.

Organizations should treat pre-upload redaction as mandatory policy rather than optional best practice for teams.

Justee uses AES-256 encryption during processing and immediately deletes all documents after redaction is complete.

Data leak prevention has traditionally focused on network-level controls, email scanning, and endpoint protection. The rise of generative AI introduces a fundamentally new vector: employees voluntarily uploading sensitive documents to external platforms in the course of legitimate work. Unlike traditional data loss scenarios, these uploads are intentional actions performed by authorized users, making them invisible to conventional DLP solutions. The National Institute of Standards and Technology has highlighted the need for organizations to develop AI-specific data governance frameworks that address these new risk patterns. Effective data leak prevention for generative AI requires a document-level approach that intercepts sensitive information before it reaches external platforms. Automated PII redaction serves this purpose by scanning documents for personally identifiable information and replacing detected entities with semantic placeholders. This technique preserves the analytical value of the document for AI processing while eliminating the data elements that create leak risk, creating a practical bridge between AI productivity and organizational security requirements.

What We Redact

Personal names, email addresses, and contact details identified and removed to prevent identity exposure

Social Security numbers, tax IDs, and government-issued identification numbers stripped before AI upload

Bank account numbers, routing numbers, and financial transaction records redacted across all document types

Client and partner company names, deal values, and proprietary terms masked with labeled placeholders

Employee compensation, performance data, and HR metrics removed from workforce documents before sharing

Risks of Sharing Unredacted Documents

Employees uploading unredacted documents to AI tools create data leaks invisible to traditional DLP systems

A single uploaded contract can expose client names, financial terms, and confidentiality-protected details

Batch document uploads for AI analysis multiply leak risk proportionally with volume processed

Generative AI platforms may train on uploaded content, permanently incorporating leaked data into models

Organizations face regulatory exposure when employee actions result in PII reaching uncontrolled external systems

How It Works

1
Intercept Before Upload

Upload any document to Justee before sharing it with a generative AI tool. Supports PDF, DOCX, and TXT.

2
Comprehensive PII Scan

The AI engine scans for over 30 entity types, catching everything from personal names to financial account details.

3
Confirm Replacements

Review each detection and its semantic placeholder. Make adjustments if needed, then finalize the redaction.

4
Share with AI Safely

Download the clean document and use it with any AI platform. Originals are encrypted and deleted immediately after processing.

Hypothetical Case Study by Justee

A management consulting firm discovered that analysts across three offices were using AI tools to summarize client deliverables and create executive briefings. The deliverables contained client organizational charts with executive names, strategic initiative budgets, competitive analysis data, and market entry plans developed under strict confidentiality agreements.

Issue Found: An internal audit found that over 60 client documents had been uploaded to AI platforms in a single quarter, including files from a Fortune 100 client containing their five-year digital transformation budget of $340M, detailed vendor evaluation scores, and personal contact information for 15 senior executives.

Resolution: The firm implemented Justee as a mandatory pre-upload redaction tool across all offices. Analysts now run every client document through automated redaction before any AI-assisted processing, ensuring client names, budgets, and contact information are replaced with placeholders.

Consulting Deliverable: Before vs. After Redaction

Why it matters: The client name, project title, multi-year budget, sponsor identity, vendor names, evaluation scores, and agreement date are all replaced. AI tools can still analyze the deliverable structure and generate briefings based on the document pattern without accessing any client-specific confidential data.

No credit card required

Traditional data leak prevention was built for a world where threats were external. With AI, the leak vector is your own employees doing their jobs. Redaction closes that gap.

Frequently Asked Questions

Traditional data loss involves unauthorized access or accidental exposure. AI-related data leakage occurs when authorized employees intentionally upload sensitive documents to external AI platforms as part of their normal workflow.

Traditional DLP tools monitor network traffic and email, but may not intercept browser-based uploads to AI platforms. Document-level PII redaction addresses the gap by removing sensitive data before it can be uploaded.

Justee removes sensitive information at the document level, ensuring that even if a file is uploaded to an AI tool, no PII or confidential data is present. It detects over 30 entity types automatically.

All documents are processed with AES-256 encryption. Files are deleted immediately after redaction is complete. No copies are retained on any server.

Yes. Justee supports team and organizational use. Paid plans offer higher document volumes and centralized billing for teams.

No. Semantic placeholders preserve document structure and relationships. AI tools can analyze patterns, identify issues, and generate summaries based on the document structure without needing actual PII.
