Hi,
We need Cybersource to support TLS 1.2 in DW8 (for old customers).
Comming February 2018 Cybersource will drop support or TLS 1.1 and TLS 1.0. From what I can tell from other payment providers, this needs to be explicit in the payment providers and there's isn't one for Cybersource.
Best Regards,
Nuno Aguiar
