Palo Alto Networks Named Best of Interop Finalist

PA-4000 Series Next-Generation Firewall Recognized for Innovation
and Enterprise Impact and Advancement
SAN JOSE, Calif.--(Business Wire)--
Palo Alto Networks has been named a security category finalist for
Best of Interop Las Vegas 2008. Interop Las Vegas 2008 will be held
April 27-May 2, 2008 at the Mandalay Bay Convention Center.

Palo Alto Networks is part of a select group of finalists in an
award nomination process that saw nearly 200 submissions. The panel of
judges, made up of award-winning editors from InformationWeek,
selected the products they believe have the greatest potential to
impact and advance business technology efficiencies. The winners will
be announced at a ceremony to be held Tuesday, April 29, 2008 at 4:00
p.m.

Palo Alto Networks is being recognized for its next-generation
firewall, the PA-4000 Series, which will further address the inherent
security risks associated with today's Web 2.0 enterprise. Just last
week, Palo Alto Networks released The Application Usage and Risk
Report, an inaugural report that tracks enterprise trends and examines
the major shifts required in enterprise risk management as end user
empowerment and next-generation application technology drastically
reduce corporate visibility and control of employee computing
activities.

"We're thrilled to be recognized in this way," said Steve
Mullaney, Palo Alto Networks' Vice President of Marketing. "Today's
more collaborative work environment and tech savvy employees require a
modern approach to information security. There is power in knowing
what's on the network, and no one wants to embrace next-generation
applications and tools at the expense of network security. The PA-4000
Series allows enterprises to reap the benefits of both worlds. It's a
win-win for everybody."
