Important PCI-DSS security standard update (December 2015)

As of April 1st 2018, Adyen merchants must upgrade their communications with the Adyen platform to support TLS 1.1 or higher.

In April 2015, the Payment Card Industry (PCI) Security Standards Council introduced v3.1 of the PCI-DSS security standard.

With this new version, the PCI Security Standards Council has specified TLS 1.2 to be the new baseline standard for encrypted communications.

Early TLS (TLS 1.0) has known weaknesses and therefore does not provide sufficient security.

Adyen recommends the use of TLS 1.2 to safeguard sensitive cardholder data during transmission over open, public networks such as the Internet.

Adyen has offered TLS 1.2 connectivity to merchants for some time already, and will be disabling earlier TLS versions on April 1st 2018.

Therefore, merchants currently using early TLS versions must work towards upgrading to TLS 1.1 or higher before this date.

We do, however, recommend scheduling the upgrade as soon as possible to adhere to Industry best practices.
