Note: Clients that do not support TLS1.2 will not be allowed to connect to c2s port. This config disables protocols from SSLv2 up to TLSv1.1 and allows only “modern” ( as of 2016) protocol TLSv1.2 and related ciphers. ProcessOne team stands on the point that security is one of the primary factors thus we will recommend strong settings but also provide compatibility for reference only for those who want and need to retain support for insecure, legacy clients and servers but understand that this settings may jeopardize security and privacy.
