Due to scheduled maintenance, mortgage information will be unavailable within Online and Mobile Banking on Thursday, December 13th from 9p.m.-10p.m. MST. We apologize for any inconvenience this may cause.
At First Interstate Bank, protecting your financial information is our top priority. To this end, we have a firewall between the Internet and our client information preventing unauthorized access as well as only communicating through web browsers that support Secure Socket Layer (SSL) 3.0 or higher. As a final security measure, we encrypt all data communication using state of the art encryption technology and Message Authentication Code (MAC). If you believe there has been an unauthorized removal of funds from your accounts related to a breach of First Interstate Bank's security measures, you may dispute the transaction and be considered for a reimbursement.
