Zix Acquires Entelligence Messaging Server Business to Strengthen Its Industry-Leading Email Encryption Solutions

The acquisition of Entelligence Messaging Server technology
from Entrust Datacard expands Zix’s email encryption capabilities
and delivery methods

(Zix), (Nasdaq: ZIXI), a leader in email security,
today announced that the company has acquired the Entelligence Messaging
Server (EMS) technology, an email encryption solution, and the related
business from Entrust
, a leading provider of trusted identity and secure
transaction technology solutions. The EMS acquisition strengthens Zix’s
email encryption capabilities, demonstrating the company’s ongoing
commitment to deliver the industry’s premier email encryption solutions.

“Zix continues to evolve our solutions to better serve our customers and
meet their needs. The acquisition of the Entelligence Messaging Server
business builds on our strength as the leader in email encryption and
allows us to accelerate our product roadmap,” said Dave
, chief executive officer of Zix. “We’re excited to unveil new
capabilities for our customers, deliver outstanding service to EMS
customers and introduce our more robust email encryption solutions.”

EMS offers rich enterprise-centric capabilities and delivery methods,
such as advanced message tracking, PDF statement delivery, high
availability on-premises architecture and standards-based end-to-end
encryption. Zix will continue to invest in and support EMS, as well as
incorporate its features into its policy-based email encryption solution ZixEncryptSM.

To ensure a smooth transition and to best meet customer needs, Zix and
Entrust Datacard have established an ongoing working relationship, and
the companies have implemented a transition agreement to mitigate any
post-close service disruption to customers. As part of the ongoing
relationship between the companies, Entrust Datacard will become a Zix
value added reseller, enabling Entrust Datacard to serve its customers’
email security needs with EMS and other Zix solutions.

“Choosing to migrate our Entelligence Messaging Server business to Zix
will provide our customers with access to the latest innovations in the
secure email market while continuing to benefit from Entrust Datacard’s
core security technologies via our ongoing relationship,” said Todd
Wilkinson, president and CEO for Entrust Datacard. “Zix is the right
partner for this transaction as they are a leader in email encryption,
and given their reputation for delivering exceptional customer support,
I’m confident our customers will recognize the value and protection in
working with Zix for their email security needs.”

Zix currently expects the transaction to have no material impact on
revenue, new first year orders or EPS.
