The ACOL web servers were recently migrated to new technology supporting improved security via Transport Layer Security (TLS) 1.2 which meets the Payment Card Industry (PCI) Security Standards Council (SSC) Data Security Standard (DSS) revised definition of "strong cryptography".
Older versions of protocols, including TLS 1.0 and 1.1, will be disabled in 2016 (dates to be announced). Modern browsers support TLS 1.2 automatically. If you use an older browser, you may need to modify your configuration settings to use TLS 1.2 or you may need to upgrade to the latest browser version.
