As part of our ongoing efforts to improve our security posture, we have added TLS 1.2 (Transport Layer Security) compatibility into PrismCore. TLS 1.2 is utilized in the communication between PrismCore and PrismWeb and is required for PCI compliance. To ensure your system is current with the latest security updates and within standards of PCI compliance, you will need to upgrade to our latest PrismCore version 28.2.7.27 by December 15, 2020.
