    ADDITIONAL INFORMATION
    Starting on July 22, 2017, accessing the Nintex Customer Portal will require TLS 1.1 and later encryption protocol in an effort to maintain the highest security standards and promote the safety of customer data. On that date we will begin disabling the TLS 1.0 encryption protocol, which will prevent access to the customer portal to anyone still using it.

    What is TLS?

    TLS stands for “Transport Layer Security.” It is a protocol that provides privacy and data integrity between two communicating applications. It’s the most widely deployed security protocol used today, and is used for web browsers and other applications that require data to be securely exchanged over a network. TLS ensures that a connection to a remote endpoint is the intended endpoint through encryption and endpoint identity verification. The versions of TLS, to date, are TLS 1.0, 1.1 and 1.2.

    The Nintex Customer Portal uses TLS as a key component of its security.
