PII Redaction
A set of technical methods for identifying and anonymizing Personally Identifiable Information before it enters a large language model. Sensitive fields are replaced with placeholders using rule-based matching or NLP-based entity recognition, satisfying data privacy compliance requirements in regulated industries such as finance and healthcare.

PII redaction should be completed before calling third-party large models, stripping emails, card numbers and the like from the ticket text.
The gateway should simultaneously take on cost-independent security control functions, such as egress inspection, PII redaction, prompt injection screening, and enforcing per-team budgets, and the routing layer and the security layer should not be built separately.
Financial institutions introducing large language models must first prove three things: a complete audit trail, PII desensitization before data enters the model, and access controls divided by team.
The technical implementation of PII desensitization is mainly divided into two categories: rule-based regular expression matching and NLP/NER model-based entity recognition.
