TLS Upgrade - 1st March 2018

Please be aware due to a change mandated by the PCI Security Council that affects all merchants and service providers processing or transmitting credit card data from March 1st 2018, OPDealer will no longer support TLS 1.0 over HTTPS on the www.opdealer.co.uk & www.opdealer.ie domains. Any older browsers that do not support TLS 1.1 or 1.2 will no longer work after this date, typically this will affect older browser versions.

Notice: Your current browser appears to support TLS 1.1 or TLS 1.2 you should need to take no futher action.

Why are we making this change?

The PCI Security Council sets the rules on which technologies are acceptable for use in transmitting cardholder data. They have explicitly identified TLS 1.0 as no longer being a strong form of encryption because it is vulnerable to many known attacks.This is not an action OPDealer is taking alone. EVERY website that transmits or processes credit card data will be making this change. If you or your customers are using an insecure or unsupported browser or API client, you will find that all secure websites will stop working very soon.
