To ensure Lender Toolkit products and services operate smoothly and securely, specific domains and IP addresses must be whitelisted by the organization’s IT team. This step enables uninterrupted access to tools, APIs, and email communications, including those involving sensitive data such as Personally Identifiable Information (PII).

Important: Lender Toolkit does not store PII data on its servers when at rest. All data is encrypted when not in use.
