Microsoft 365 for Lending: Collaboration With Borrower Data Protection

A lender runs M365 with the default configuration. Underwriters share borrower financial documents in Teams channels. Loan officers email borrower application data to each other. Processors store signed disclosures in personal OneDrive folders. Meanwhile, customer non-public personal information (NPI) falls under the GLBA Privacy Rule and Safeguards Rule with specific protection requirements. The compliance officer reviews the environment and identifies multiple findings: no sensitivity classification on borrower documents, no DLP preventing NPI from leaving approved channels, no access controls aligned to business need, no audit logging on NPI access, and no documented alignment to the GLBA Safeguards Rule. The next state examination will focus here.

Lender M365 done right addresses GLBA Privacy Rule and Safeguards Rule from the start. Sensitivity labels for NPI, borrower application data, closing documents, and other content with specific protection requirements. DLP policies preventing NPI from leaving approved channels. Access controls aligned to business need (loan officers to their own pipeline, underwriters to assigned queues, processors to their workload). Audit logging on NPI access for examination support. Document retention aligned to record retention requirements (generally 25+ months for mortgage, varies by loan type and state). eDiscovery readiness. Done with this discipline, M365 supports operations safely. Done without it, state banking examination finds the gaps.
