ZixIt Selected by Four Healthcare Companies to Provide Secure Email; ZixMail Chosen by Healthcare Providers to Address HIPAA Compliance Requirements

DALLAS, Aug 14, 2001 (BUSINESS WIRE) --

ZixIt Corporation
(Nasdaq:ZIXI) announced today that WellMed Medical Management, IPC-The
Hospitalist Company, Texas Oncology, P.A., and Radiology Associates of
Tarrant County have all chosen ZixMail(TM), a secure email application
and service, to ensure the security of documents sent and received by
email via the Internet.
	   This will help them comply with Health Insurance Portability and
Accountability Act (HIPAA) regulations for electronic messaging. All
companies conducted thorough product evaluations before selecting
ZixMail and are now in the first stage of phased-in deployment.
	   "The healthcare industry is increasingly turning to the Internet
to conduct business. Our objective is to make the medical profession
aware that HIPAA compliance in electronic messaging can be simple with
ZixMail," said Steve Gersten, senior vice president of sales and
marketing for ZixIt. "ZixIt facilitates healthcare professionals,
doctors, clinics, hospitals, pharmacies, insurers, health plans, and
all other healthcare providers in complying with new patient privacy
laws. Not only do we easily satisfy their stringent security
requirements, our unique certified receipt feature will actually help
them increase efficiencies and decrease costs."
	   ZixMail works with all popular email systems and improves Internet
communications security beyond existing firewalls, enabling users to
easily send encrypted and digitally-signed communications to anyone,
even non-ZixMail users. Users do not change their email addresses or
systems. ZixMail's certified receipt feature, which provides proof of
delivery by irrefutably establishing when a message was sent and
opened, further increases its usefulness as an everyday business tool.
Both large enterprises and small businesses can benefit from ZixMail's
flexibility and scalability.
