## About NoPII
NoPII is a reverse proxy designed to protect sensitive data in Large Language Model (LLM) interactions by detecting and tokenizing personally identifiable information (PII) before it leaves your environment. This ensures that data such as names, Social Security Numbers (SSNs), email addresses, and more are replaced with deterministic, format-preserving tokens prior to reaching the LLM provider. Upon receiving the LLM's response, NoPII detokenizes the data, restoring the original values seamlessly. Integration is straightforward, requiring only a single line of code change to your existing setup. Key Features and Functionality: - PII Detection and Tokenization: Automatically scans incoming requests for PII, including names, emails, SSNs, and addresses, replacing each with a consistent token before the request exits your network. - Sanitized Forwarding: Transmits the sanitized payload to supported LLM providers (such as OpenAI, Anthropic, and Google) using your own API key, ensuring that no PII crosses the boundary. - Response Detokenization: Intercepts the LLM's response, mapping tokens back to their original values, and delivers the fully restored response to your application. - Rapid Integration: Achieves time-to-protection in under five minutes with a simple base URL change, eliminating the need for SDKs, middleware rewrites, or architectural modifications. - Intelligent Tokenization: Maintains entity relationships across messages through deterministic tokenization and employs context phrase neutralization to prevent LLM safety refusals on tokenized data. - Compliance and Security: Operates on PCI Level 1 and SOC 2 Type II certified infrastructure, providing a full audit trail for every request and ensuring fail-safe operations where PII never leaks, even in error scenarios. Primary Value and User Solutions: NoPII addresses the critical need for safeguarding sensitive information in AI-driven applications by preventing PII exposure during LLM interactions. By seamlessly integrating into existing workflows with minimal code changes, it enables organizations to leverage the power of LLMs without compromising data privacy or regulatory compliance. This solution is particularly beneficial for industries with stringent data protection requirements, such as healthcare, financial services, legal, customer support, and human resources, allowing them to adopt AI technologies confidently while maintaining the highest standards of data security.
