Enterprise Bank & Trust Cracks the Password Management Problem with Imprivata OneSign; Ease of Configuration and Administration, along with Strong Biometric Support, Set OneSign Apart

Business Wire, Jan 9, 2006

LEXINGTON, Mass. -- Imprivata(R), Inc., the Enterprise Single Sign-on (ESSO) appliance company, today announced that Enterprise Bank & Trust, a St. Louis, Missouri-based financial services institution, has implemented Imprivata OneSign(TM) as its ESSO solution. After an exhaustive review process, including intensive on-site testing, Enterprise Bank chose Imprivata OneSign, the industry's only ESSO appliance, over other SSO solutions because "it really worked!" As the only company that is laser-focused on ESSO, Imprivata provides the full-service financial organization with the ability to quickly, affordably and securely SSO-enable business-critical applications, successfully achieving increased password security and reducing IT help desk costs in a matter of days.

"With security regulations intensifying and passwords becoming increasingly complex, the headache of password resets was beginning to burden our IT as well as our users," said Steve Siress, network systems manager at Enterprise Bank. "With Imprivata's quick to deploy, out-of-the-box solution, we've found a way to comply with audit regulations while significantly reducing help desk costs and improving employee productivity. Our employees absolutely love the new system, especially the users that have been given biometrics."

Due to the large number of applications requiring unique passwords, as well as the need for higher security in the financial services industry, Enterprise Bank turned to Imprivata to execute on a more secure, efficient and effective password management policy. Prior to employing OneSign, Enterprise Bank was struggling with the need to implement a more complex password system in order to satisfy audit regulations mandating stringent password policies in the financial services arena. The IT department could see that this implementation would foster significant frustration amongst users and IT staff alike. Users would likely have struggled to remember their many strong passwords, ultimately resorting to either weakening security by writing passwords down, or making frequent calls to the help desk for password resets, leading to increased costs and a significant loss of employee productivity.

While Enterprise Bank tested multiple SSO products in the company's evaluation process, Imprivata's ESSO solution stood apart from other offerings because it not only simplified password management for Enterprise Bank employees, but it also alleviated strain on the IT staff, all while maintaining a high level of password security. Siress continued, "Imprivata has done a remarkable job of designing an interface that was easy to learn and simple to add more applications to the Single Sign-on process." OneSign integrates seamlessly with Enterprise Bank's biometric implementation and, as a self-updating hardware appliance designed for organizations of all sizes, it also provides users with a common log-in across all applications, eliminating the need to remember multiple passwords. Furthermore, Imprivata's Application Profile Generator(TM) self-learns the behavior of any application's authentication processes, so the IT department no longer needs to make costly and time-consuming modifications to existing code.

"Financial services institutions like Enterprise Bank are realizing that while a secure password policy is critical to the success of their organizations, implementing a stronger system can be very costly and can cause significant losses in user productivity," said Omar Hussain, president and CEO of Imprivata. "OneSign allows these institutions to achieve a high standard of security in an affordable, easy-to-manage way. We are pleased to help Enterprise Bank maintain the highest standard of service to its clients by offering a simple, effective solution to the organization's password management issues."
