Got this email from 2CO today. Most people probably won't have to worry about this, but I know there are still some using SSL 3.0 on their servers. If you are one of those people, now is a good time to stop and switch over to the new PCI standard (TLS1.1 & TLS1.2).
From protecting the identity of our Merchants to securing your customers' transactions, our focus here at 2Checkout is to process your payments securely and efficiently while adhering to the latest changes and updates within the payments industry.
The Payment Card Industry (PCI) Security Standards Council (SSC) has released its latest data security standard (DSS) 3.1, which mandates all businesses move away from Secure Sockets Layer (SSL) web encryption because it's no longer considered strong enough. Therefore, starting June 1, 2017, 2Checkout will no longer support SSL 3.0 and TLS 1.0. This means that all API requests, Vendor Admin sessions and standard checkout processes will need to use TLS 1.1 or TLS 1.2.
As a Merchant, please check to ensure your connectivity will not be affected – you may need to make updates to your servers, programming language and even the browser you are using immediately.
