NetScout Systems has acquired privately held Simena, based in Sterling, Virginia, a provider of high performance, low-latency IP packet flow-based network monitoring switching technology that enables IT organizations and service providers to aggregate, filter and control network traffic for data, voice, and video monitoring and CyberSecurity deployments.

Simena’s technology will further strengthen NetScout’s Unified Service Delivery Management strategy – extending the company’s pervasive visibility capabilities by enabling fine-grained packet-flow control for monitoring environments to better leverage critical network monitoring points.

"To overcome the challenges of growing IP traffic volume and the increasing diversity of network traffic, IT teams need to target specific application traffic for more efficient performance monitoring and CyberSecurity activities. A key aspect of these challenges is improving the control and distribution of IP traffic being fed into our nGenius InfiniStream appliances to achieve targeted visibility into business applications and unified communication services to understand the user experience,” said Anil Singhal, president and CEO, NetScout.

“As we continue to execute on our Unified Service Delivery Management strategy, enabling our customers to achieve truly pervasive visibility is one of our top priorities. Our acquisition of Simena brings important packet-flow switching technology that will help our enterprise, public sector and service provider customers tackle diverse traffic requirements and improve the efficiency, control and distribution of critical network-based monitoring traffic.”

With an established installed base, including some of the most demanding real-time financial services environments, Simena technology delivers deployment-proven, high-density 10 Gigabit Ethernet switching capabilities. Architected to deliver ultra-low latency while performing granular wire-speed filtering of IP-based network traffic, the Simena switching technology aggregates, load-balances and disseminates network traffic allowing the IT organization to target and control traffic delivery to monitoring, management or CyberSecurity systems.

The Simena packet flow switching product will become immediately available to NetScout customers and existing Simena customers will now be supported by NetScout. Existing Simena employees will be integrated into NetScout’s ongoing operations.
