Tumbleweed Poised to Benefit From Russia's Tech Boom With Addition of New Channel Partner

Rainbow Technologies Partners with Tumbleweed to Sell Secure
Content Delivery Solutions to Private Organizations and Government
Agencies Throughout Russia
REDWOOD CITY, Calif.--(Business Wire)--
Tumbleweed(R) Communications Corp. (NASDAQ:TMWD), a leader in
managed file transfer and email security, today announced continued
expansion in the EMEA region with the signing of a new premier
distributor in Russia. Rainbow Technologies has joined Tumbleweed's
partner alliance to help meet the demand across Russian private and
government sectors for innovative, reliable and easy-to-use secure
content delivery solutions.

"Investment in IT infrastructure has seen double-digit growth in
parts of Central and Eastern Europe -- and now that infrastructure is
more mature, IT organizations will predictably turn their attention to
security," said Craig Whitney, Tumbleweed Managing Director for EMEA,
"Rainbow Technologies has been at the forefront of fulfilling demand
and is a trusted partner to many private enterprises and governmental
offices. We see them as a strategic partner as we enter this region of
Europe."

The current business climate in Russia makes this a particularly
opportune time for such a partnership. By all counts, Russia has seen
enormous IT growth since 2002, and Esther Dyson, a well known U.S.
thought leader on emerging digital technologies, has publicly wagered
that by 2012, major American newspapers will refer to Russia as "the
world leader in software development." And if Russia's huge presence
at CeBIT in 2007 was anything to go by -- over 150 major Russian IT
exhibitors spanning consulting, outsourcing and software -- the hype
may be real.

This new maturity in Russia's IT space makes it ripe for the next
piece of the puzzle -- IT security, and an emerging demand in the
government sector for IT products and solutions. Tumbleweed
SecureTransport(TM) is a leading Managed File Transfer solution that
is uniquely positioned to benefit from this new phase of growth in
Russia's IT sector. Initial MFT revenue opportunities are expected to
be in Russia's commercial sector across businesses of every size.
Meanwhile, in the banking and government sectors -- where regulation
is heavy and encryption guidelines strict -- Rainbow Technology is
aggressively pursuing the required certifications.

"We see tremendous opportunity with Tumbleweed -- in particular
with their managed file transfer product, SecureTransport," said Yuriy
Ivanovich Kryukov, CEO of Rainbow Technologies. "As organizations
increasingly look for ways to safeguard valuable business content,
SecureTransport provides an effective, easy-to-use product that
enables greater control of business data. There's no other product
quite like it available in Russia today."
