OPNET Technologies, Inc.: Press release

Evaluation Based on Completeness of Vision and Ability to Execute

BETHESDA, Md., 2011-09-21 22:56 CEST (GLOBE NEWSWIRE) --
OPNET Technologies, Inc. (Nasdaq:OPNT) today announced it has been positioned
by Gartner, Inc. in the "Leaders" quadrant of the "Magic Quadrant for
Application Performance Monitoring" published on September 19, 2011, and
written by Will Cappelli and Jonah Kowall. Gartner evaluated 29 vendors in the
report. 

OPNET's solutions for application performance management dramatically
accelerate problem resolution, enable problem prevention, and improve the
efficiency of both IT infrastructure and IT staff resources. The report
considered the solutions in OPNET's APM Xpert™ suite, including: 

  -- AppResponse Xpert™ uniquely combines end-user experience monitoring and
     in-depth analysis of the behavior and performance of the underlying
     network. It leverages the network's central role as a conduit for data and
     transactions to obtain complete visibility of IT services across the
     enterprise. Real-time on-board analytics determine which components in the
     application infrastructure are contributing most to delays.
  -- AppInternals Xpert™ looks deep into the complex software frameworks of
     modern applications, leveraging vast amounts of performance and forensic
     data to support all aspects of service assurance from the server
     perspective. It performs high definition monitoring, forensic data
     collection for all transactions, and powerful analytics for any type of
     application, and excels in particular in Java and Microsoft .NET
     environments.
  -- AppMapper Xpert™ automatically produces a run-time application map,
     identifying the underlying application and infrastructure components that
     enable a production application. It leverages a rich repository of
     operational data obtained from OPNET solutions and instrumentation already
     deployed for performance management.
  -- AppTransaction Xpert™ and AppTransaction Xpert Packet Trace Warehouse
     provide centralized management and in-depth analysis of transaction
     forensics collected across the enterprise.
  -- AppSQL Xpert™ provides deep visibility into database performance through
     real-time monitoring of a broad range of metrics, with drilldowns to
     fine-grained forensic database transaction data for troubleshooting. It
     performs detailed tracking of database usage for trending and performance
     optimization. AppSQL Xpert offers an agentless approach that imposes zero
     overhead on database operation.
  -- AppSensor Xpert™ uses agentless, remote instrumentation to capture
     additional performance information from all types of infrastructure
     components, including servers, application components, network devices,
     storage systems, and manufacturer-specific management systems. It supplies
     this data to OPNET's APM solution suite for a more complete picture of
     end-to-end application performance.

"We believe OPNET introduced significant new APM capabilities that were
evaluated in this year's 'Magic Quadrant for Application Performance
Monitoring'," stated Alain Cohen, President and CTO of OPNET. "These include
groundbreaking solutions for application dependency mapping, end-to-end
transaction following combined with deep tracing, cloud-capable virtual
appliances and agents, and advanced analytics for automated troubleshooting.
Together with OPNET's outstanding market share growth, we believe this latest
report by Gartner confirms that OPNET is a leading innovator in this space,
delivering a robust suite of well-integrated solutions to address all the
functional components of APM - solutions that are technologically among the
best in our industry."
