Phelps County Regional Medical Center Selects Voltage Security and CipherTrust to Provide Privacy Protection
for E-mail Communication

Voltage Security Products Featuring Identity-Based Encryption (IBE) and CipherTrust’s Policy Management Provide Compliance for Regional Healthcare Center

Baltimore, MD—HIPAA Summit—April 7, 2005---Phelps County Regional Medical Center (Phelps), serving the medical needs of Rolla and south central Missouri, today announced that it has selected Voltage Security, Inc., a global leader in enterprise privacy management, and CipherTrust, Inc. (www.ciphertrust.com), the leader in messaging security, to ensure compliance for the April 20th HIPAA security rule deadline. The combination of Voltage SecureMail™, Voltage Identity-Based Encryption or IBE Gateway Server™ and CipherTrust IronMail® will provide policy-driven encryption to protect private health and financial information in e-mails flowing in and out of the medical center. Phelps, a 235-bed acute-care hospital, selected the CipherTrust/Voltage solution due to its easy-to-use, flexible administration capabilities. Approximately 800 employees at Phelps are currently using the Voltage/CipherTrust solution.

“Our goal is to meet the standards set-forth in federal patient privacy regulations, such as HIPAA, and safeguard all Protected Health Information (PHI) leaving and coming into the hospital. At the same time, we want to continue to offer our customers and vendor partners the convenience and efficiency of e-mail communication. Voltage IBE, combined with the CipherTrust IronMail appliance, provides us with all of this plus a total e-mail security solution,” said Mary Crouch, CIO/IT security officer, Phelps County Regional Medical Center. “We looked at several solutions and none of them offered the combination of automation, ease-of-use, functionality and reporting that we knew would be best for our users. I learned to use it in a couple of minutes on my home computer, so I knew my end users would not need extra training. Installation of the system at the hospital has been quick and efficient.”

CipherTrust’s IronMail solution is an all-in-one appliance that sits at the enterprise gateway blocking inbound e-mail threats and protecting outbound message content from policy violations. IronMail examines the content and handles it based on administrator-defined policy.  The message is then routed to the Voltage IBE Gateway Server where it is encrypted and delivered to the Internet by IronMail. IBE greatly simplifies the process of protecting private digital communications by using a common identity, such as an e-mail address, as a public key and no certificates need to be managed and no pre-enrollment in the system is required.

“We are finding tremendous interest in policy-based encryption. It is the ideal solution for organizations that want to take compliance decision-making out of the hands of end users, and automatically scan and encrypt all messages containing sensitive, private information. The Voltage IBE Gateway Server combined with the CipherTrust IronMail appliance helps customers comply with key regulations automatically and efficiently,” said Wasim Ahmad, vice president of marketing, Voltage Security, Inc.

“Adding the Voltage IBE Server to IronMail’s Privacy Architecture has enabled CipherTrust customers to conduct secure business communication anytime, from anywhere,” said Mike Rothman, vice president of marketing, CipherTrust. “Enterprises such as Phelps choose this solution to ensure the secure delivery of business-critical messages and to help fill in a piece of the compliance puzzle for regulations such as HIPAA. Not only is it critical to protect e-mail servers from incoming threats such as viruses and worms, it is just as vital to protect legitimate business messages from reaching the wrong hands or possibly violating corporate or regulatory policies.”
