Authorize.Net is here to help merchants with PCI DSS requirements that all payment systems must disable early-version TLS by 2018. Transport Layer Security (TLS) is a technology used to encrypt sensitive information sent via the Internet. TLS is the replacement for Secure Sockets Layer (SSL). Learn what we are doing in preparation for this requirement.


Authorize.Net helps merchants with new PCI DSS requirements requiring disabling of older Transport Layer Security (TLS) protocols, TLS 1.0 and TLS 1.1. To help merchants identify if they’re using one of the older TLS protocols, Authorize.Net temporarily disabled those connections for a few hours on January 30, 2018 and then again on February 8, 2018.
