As part of our process of continually improving security and working to ensure that the processes and technology guarding your data are up to date, Tradeshift is planning to attain PCI Level 1 accreditation this year.  One of the necessary changes to provide this increased level of protection involves discontinuing the use of TLS 1.0 for HTTPS connections to the web portal at as it is susceptible to attacks that can compromise the confidentiality of your connections, putting your data at risk of disclosure while in transit.
What this means to you?
As of 2013, all major browsers now support TLS 1.1.  Users running browser versions previous to this (generally Internet Explorer versions 10 or earlier) which do not support TLS 1.1 or 1.2 by default will need to upgrade or manually enable TLS 1.1 using the steps below to access the web portal after this change.  All other platform integrations will continue to operate as-is with no changes.  You can validate support in your browser by checking on the SSL Labs client tester here.  If your browser does not support TLS 1.1 or 1.2, you will be affected by this change.  Please coordinate with your IT team to ensure that you will have an alternative up-to-date browser you will be able to use after the changeover date.

Instructions for enabling TLS 1.1 on earlier versions of Internet Explorer (8,9 and 10 only):
  1. Go to Tools and select Internet Options
  2. Select the Advanced tab in Internet Options
  3. Enable(check) TLS 1.1, TLS 1.2 and also disable (uncheck) SSL 3.0 for additional security
