GPT Guard

GPT Guard is an enterprise chat platform designed to prevent data leaks when using AI. Instead of blocking sensitive information from reaching large language models (LLMs), it automatically detects and masks personally identifiable information (PII), protected health information (PHI), and other confidential data before sending requests to the AI. This means you can upload internal documents — contracts, patient records, employee feedback — and ask questions without worrying about your data ending up in training sets or being exposed to unauthorized parties.

The tool uses a technique called context-preserving masking, which replaces sensitive data with placeholders so the AI can still understand the query and provide relevant answers. It also features HyperSearch RAG, a retrieval-augmented generation system that lets you upload unlimited files and chat with any document. Other highlights include OCR support for extracting text from images, the ability to choose from multiple LLM models (GPT, Claude, and others), and an option to chat with the internet for additional context. You can see exactly which sources GPT Guard referenced for each answer, adding a layer of transparency.

GPT Guard is built for organizations that handle sensitive data, especially in healthcare, finance, and legal sectors. Compliance teams will appreciate its built-in support for HIPAA, GDPR, and Middle East regulations. Use it to analyze patient records, audit internal communications, or query customer support tickets without exposing personal data. The platform can be deployed on-premises or as a SaaS, making it flexible for different security requirements. It integrates with corporate login systems like SSO and supports multitenancy, so large organizations can manage access for different teams. The bottom line: GPT Guard lets companies unlock AI’s benefits without compromising on privacy or compliance.
