FINRA to disable Transport Layer Security (TLS) version 1.0 and version 1.1

Effective 09/30/2020 FINRA will disable support for Transport Layer Security (TLS) protocol versions 1.0 and 1.1 for all web applications/API connections. Firms using older clients/browsers that do not support TLS version 1.2 and above will not be able to establish connectivity with FINRA web applications/APIs.

To minimize the impact of this change please ensure your browsers/systems are capable of supporting TLS 1.2 and above. You can also validate the client/browser by navigating to https://www.finra.org where TLS1.0 and 1.1 has already been disabled.
