CAT supports network access for reporting order events via Private Lines (i.e., wan circuits and cross connects) and Remote Client VPN connections. FINRA CAT, LLC will organize Private Lines connectivity options with Industry Members through the use of a Managed network Service Provider (MNSP). For Industry Members who require Private Line connections, Industry Members will be responsible for procuring access from an approved (MNSP) to authenticate and submit SFTP data uploads. The Reporter Portal will also be available over the MNSP connection(s). Alternatively the Industry Members may access the Reporter Portal via a browser based Remote Client VPN connection that will also be made available to Industry Members. All Industry Members must have access to the SFTP and CAT Reporter Portal in order to report and receive information about file and record rejections, statistics about order reporting, and announcements. In order to use SFTP and CAT Reporter Portal, Industry Members must register with CAT prior to the beginning of Phase 2a. If an Industry Member is using one or more third parties for reporting, it must work closely with those organizations in the CAT testing environment to resolve any issues before it begins reporting to the CAT production environment. More details regarding the MNSP and VPN access methods will be published in July once the MNSP vendor(s) is selected. For additional information, refer to the CAT Reporting Technical Specifications for Industry Members.
