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). At First Interstate Bank, we guarantee you will be covered 100% for all funds improperly removed from your accounts while we are handling your transactions. We will reimburse you for any unauthorized online removal of funds from your accounts provided it is not the result of client irresponsibility.
