The bank technology vendor S1 Corp. said Monday that it is combining its three business lines.

The Norcross, Ga., company's S1 Enterprise, Postilion and FSB Solutions each served a different segment of the banking market — Enterprise, for instance generally served larger financial institutions than Postilion did.

Johann Dreyer, S1's chief executive, said the company will now market all of its products under the S1 name. "A single brand provides more clarity on the family of solutions our entire organization has to offer and how they can benefit banks, credit unions, retailers, and processors around the world," he said in a press release.

Dreyer said the rebranding was done in response to "input from key stakeholders," including prospective customers and industry analysts.
