SSL and TLS security protocols on servers upgrade beginning July 16, 2018

The SSL V3 and TLS V1.0 security protocols are no longer considered secure and compliant with current security standards.  In order to ensure that security compliance is maintained throughout all of ISC’s managed server infrastructure, ISC will be removing the use of the SSL V3 and TLS V1.0 protocols. Both the SSL and TLS protocols will be upgraded to fully compliant versions.

The work to upgrade the SSL and TLS security protocols will begin on July 16, 2018, and is expected to be completed by September 30, 2018. In most cases, the security protocol upgrades will be transparent and non-disruptive. For those applications running on servers that are directly affected by this upgrade initiative, ISC will be working directly with clients to test and upgrade the security protocols.

If you have any questions regarding this initiative, please contact ISC Client Care at
