Securing the Accounts Payable TIN Match Extract File in Report Manager (FSCM)

Curious how customers are securing their Accounts Payable TIN extract files in Report Manager. We just started using the TIN match process within PeopleSoft this year and are wondering if there is a need for specific security to access the .txt extract file, since it does contain unmasked SSN numbers. Do other customers customize the app engine to output to a secure file location outside of PeopleSoft, or is the delivered Process Scheduler Process > Process Definition Options Process Security enough to limit access? Current FSCM version 9.2, PUM 55 and PeopleTools 8.62.06.
