TLS 1.2 Certification

Transport Layer Security (TLS) is a critical security protocol used to protect web traffic. It provides confidentiality and integrity of data in transit between clients and servers exchanging information. As part of ongoing efforts to modernize platforms, and to improve security and reliability, TLS 1.0 and 1.1 will be deprecated by all ERCOT communication.

The TLS 1.2 certification requires ERCOT to disable all TLS 1.0 and TLS 1.0 communications with its partners.  After the TLS 1.0 and TLS 1.1 is disable/deprecated ERCOT will only accept TLS 1.2 ciphers with its partners.
