NetScout Ranked Top Vendor in Worldwide Network Performance Management Market

WESTFORD, Mass.--(Business Wire)--
NetScout Systems today announced that IDC, a leading provider of global IT
research and advice, recently released a report titled "Worldwide Network
Performance and Operations Management 2009-2013 Forecast and 2008 Vendor
Shares,"1 in which NetScout is ranked as the top vendor in the market segment
with a 14 percent market share position for calendar year 2008.

The IDC report, published in April 2009, identifies NetScout as ascending into
the top-tier of the performance and operations management market segment. "In
2008, NetScout broke ranks and through the acquisition of Network General moved
into the top 5 with the big system IT vendors in terms of revenue earnings. It
is important to note that this does not mean that NetScout is displacing system
IT vendors but rather that its segment of the market is growing at a faster rate
than the system IT vendors. Its solution is a complementary one, and it has a
tight relationship with other tech vendors such as HP and IBM."

"Companies need to do more with less and that means fewer staff," said Abner
Germanow, director, enterprise networking at IDC. "IT departments must improve
their effectiveness and that is being reflected in strong growth among vendors
offering greater visibility into networking performance and troubleshooting.
Additionally, these tools provide information that can then be shared across IT
organizations, which in turn improves overall operational efficiency."

The IDC report further highlights: "While performance management and
optimization have been all the buzz, it really comes down to understanding and
managing IP traffic over the network. That means better understanding of what is
running on the network… deep packet inspection (DPI), and analytics are no
longer nice to have but an integral part of networking solutions moving
forward."

"Our vision and strategy continues to be focused on meeting IT`s need to more
effectively assure service delivery in the rapidly transforming IP network
environment," said Steven Shalita, vice president, marketing for NetScout
Systems. "The company`s acquisition of Network General and subsequent technology
integration has been a key part of our strategy to extend our product portfolio
and its value to IT by leveraging the strengths of two market leading companies.
Our execution of this strategy has enabled us to deliver compelling solutions
that position us as a strategic vendor, which is reflected in IDC`s recently
released market data."
