A developer has created a custom, in-process PII redaction and audit logging solution for LiteLLM, named Cloakwall, to avoid the complexities of external dependencies and enterprise licensing. This solution uses regular expressions with advanced validation, such as the Luhn algorithm for credit card numbers and a modulus-11 check for NHS numbers, to accurately identify and mask sensitive information. The system also implements a secure, chained SHA-256 hashing mechanism for audit logs, ensuring data integrity and preventing the log from containing the redacted PII itself, with options for SIEM export.
