PayPal upgrade to TLS 1.2

Transport Layer Security (TLS) is an important protocol used to securely communicate with web servers and service providers such as PayPal or Authorize.net. Earlier this year, Paypal announced that they would no longer support TLS version 1.0 or 1.1 connections and that they would force all connections to use TLS version 1.2 after June 30th of 2017. Any provider using TLS 1.2, will have protocols in place that will improve security for all external request made on their networks. This security includes any transactions request made to you them from any website owned by our clients.

Among servers that are hosted by our company, the customers who have commerce sites hosted on older operating systems are the most affected by the change to TLS version 1.2. Customers using Windows 2003 shared hosting servers will not be able to communicate using TLS version 1.2. Other clients that may experience issues are Cloud customers who are using older Operating systems.

Here is a list of online processors that will be potentially impacted by the upgrade to TLS version 1.2.

  • PayPal – listed as switching over on 06/30/2017.
  • Authorize.net – listed as switching over on 09/18/2017.
  • Comodo – switched over in May of 2017.
  • Salesforce – listed as switching over on 07/22/2017.
  • 2Checkout – Switched over 06/30/2016.

If a customer’s server can only support TLS or older, Our systems administration team has created a proxy system to minimize the impact our customer’s experience. The proxy works by sending older TLS clients who send a request to PayPal, or one of the other providers, first through an SSL generated by our company; then it is sent on to Paypal using TLS 1.2.

Some customers will have to make minor changes to their system. If any of your sites verify the certificate issuer before the transaction is processed, you will need to remove this feature. This is great security practice, but will no longer allow your transactions to be processed through TLS 1.0.

If you have any questions or have another provider that you would like to connect to our proxy system, please contact us our support team for assistance.
