Our Story

About Security First Bank

Security First Bank is a Nebraska-chartered, privately-held community bank with 25 branch locations and 12 insurance offices throughout Nebraska and southwest South Dakota. We provide community banking services from the farm and ranch towns in rural Nebraska to the hub cities of Lincoln and Rapid City. Each branch is managed locally, and our employees are part of the communities we serve. This gives us valuable, local perspective and a personal commitment to servicing your financial needs.

Security First strives to improve the lives of the families and business we serve with creative, high-quality financial services. We believe that attention to detail, flexible and innovative services and remarkable customer care are the pillars of successful community banking, and we’ve been committed to those standards since our founding.

In 1898, nine ranchers in northwestern Nebraska started Stockmens National Bank of Rushville, Nebraska. Fast-forward 125 years, Stockmens National Bank – now known as Security First Bank – has grown to encompass 25 bank branch locations, 12 insurance offices, one loan production office, and employs nearly 300 people throughout Nebraska and southwest South Dakota.

For 125 years, we’ve been “the bank” of our communities. As we celebrate and reflect on our history, we remain committed as ever to meeting the financial needs of the families and businesses we serve – now and for generations to come.
