Zix Corporation CEO Provides Corporate Update for Third Quarter 2009

Current estimates have the Company expecting to achieve its guidance

DALLAS, Oct. 8 /PRNewswire-FirstCall/ -- Zix Corporation (ZixCorp(®)),
(Nasdaq: ZIXI), the leader in hosted services for email encryption and
payor-sponsored e-prescribing, today offered a corporate update by its chief
executive officer, Rick Spurr.

"The third quarter was another solid quarter for ZixCorp and we are on target
to report within the range of our previously-issued guidance," said Spurr.
"Preliminary estimates are that we should meet our revenue guidance of $7.5 to
$7.8 million and our guidance for adjusted earnings per share (which excludes
non-cash stock-based compensation, non-recurring items, and uses an effective
tax rate of less than 1 percent) of $0.00 to $0.01 per share. If these
preliminary estimates hold true in the final numbers for the quarter, each
would represent a record result for ZixCorp."

"In our Email Encryption business, ZixCorp delivered $6.5 million in total
orders in the third quarter which is traditionally our slowest quarter of the
year in our Email business. This included $1.3 million in new first-year
orders, a 13 percent increase over the 2008 third quarter," continued Spurr.
"We saw continued success in both healthcare and financial services,
demonstrating the strength of our Software as a Service (SaaS) solution. With
a strong renewal rate of 91 percent and several competitive win-backs during
the quarter, we remain well-positioned for future success in this business by
capitalizing on our recognized leadership position in the industry."

About the Company's e-Prescribing business, Spurr said, "As we continue our
review of strategic alternatives for our e-Prescribing service, we remain
committed to operating on a business-as-usual basis with respect to executing
our existing contracts and providing quality services to our customers. Our
PocketScript business achieved our e-Prescribing deployment guidance for the
third quarter with approximately 210 new deployments. Also, in the third
quarter, which historically shows some drop-off with many physicians taking
vacations over the summer months, we processed over 2.3 million scripts, an
increase of approximately 16 percent compared with the third quarter in 2008."
