In an effort to maintain the highest standards in data security, Security National Bank’s online banking will no longer be compatible with older versions of operating systems or browsers that do not support TLS 1.2. After May 15, 2017, users need to ensure that TLS 1.2 is enabled. Please see the chart below to verify your online banking will continue to work after this date. If you have any questions or need assistance enabling TLS 1.2, please call Security National Bank’s online banking department at 580.234.5151.
