AI Data Protection: How Privacy SaaS Secured LLM Workflows
Eliminated 100% of PII exposure risk while integrating OpenAI, Anthropic, and Google LLMs
The Challenge
Our client, a high-growth compliance startup, sought to bridge the gap between enterprise AI adoption and strict data residency requirements. They identified that major corporations were banning Generative AI tools due to the inherent risk of sensitive data being used to train third-party models or leaked during prompt submission.
Core Problem
Existing redaction tools were too slow for real-time chat or failed to catch PII hidden in complex formats like images and PDFs. Furthermore, the client lacked a monetized, scalable infrastructure that could handle multi-provider LLM integration while providing a high-fidelity audit trail for compliance officers.
Without a robust, automated scrubbing mechanism, the client’s enterprise users faced a choice between total AI stagnation or risking multi-million dollar fines under GDPR, CCPA, and HIPAA regulations.
The Solution
EnDevSols engineered a secure AI proxy platform featuring a 'two-pass' PII detection system. This architecture intercepts every prompt, applies advanced NLP and Vision LLM logic to scrub PII, and presents a 'Preview-Confirm' workflow to the user. We utilized AES-256-GCM encryption for all data at rest and in transit, ensuring that even if intercepted, the data remained indecipherable.
Secret Sauce
Our 'Secret Sauce' was the integration of a Vision LLM for multi-modal text extraction. Unlike standard OCR, our system understands context, allowing it to accurately redact sensitive data embedded in unstructured layouts, tables, and images before the payload ever reaches a third-party API.
