Frost & Sullivan Commends Sonus Networks' Innovation-backed Growth in the Enterprise Session Border Controller Market

Recent Analysis of E-SBC Market Makes Sonus Clear Recipient of "2017 North American E-SBC Company of the Year" Award

SANTA CLARA, California, June 7, 2017 /PRNewswire/ -- Based on its recent analysis of the enterprise session border controller (E-SBC) industry, Frost & Sullivan recognizes Sonus Networks (Sonus) as the 2017 North American E-SBC Company of the Year. Sonus is regularly featured on the top five E-SBC leaderboard for its ability to anticipate and stay ahead of customer demands and technology trends. Sonus garnered 13% of the E-SBC market's revenue share in 2015, complementing its strong competitive position in the service provider SBC market, where it boasts a clientele of several large, influential carriers.

"Following its 2012 acquisition, Sonus consolidated the enterprise-focused network equipment technologies (NET) products under the common Sonus brand," said Frost & Sullivan Industry Analyst Michael Brandenburg. "This enabled the company to extend its already-established brand equity into the E-SBC market, as well as encouraged service providers to promote Sonus' products among business customers."

While some vendors are reducing the number of E-SBC solutions they offer today, Sonus is working to increase customer deployment flexibility with the broadest portfolio of SBCs on the market. Sonus' most recent hardware addition, the SBC 5400, was purpose-built to meet the unique real-time communications challenges large enterprises face. The Sonus SBC 5400 is the industry's highest performing mid-range SBC with user-configurable port speeds from 2GB to 10GB for multi-media traffic. On the virtual front, Sonus recently added the SBC SWe Lite. This E-SBC, built for the small and medium-sized business (SMB) market, delivers a virtualized customer premises equipment (vCPE) option for interworking, security, and survivability for unified communications (UC) and SIP trunking. The unique power of Sonus' portfolio is that whether an SBC is deployed in a physical or virtual form factor, the tools to deploy, configure, and maintain the SBC remain consistent. This enables customers to maximize their training and knowledge of working with Sonus products, even as they transition to a software-only environment.

Sonus is also innovating in real-time communications security by partnering with leading security vendors.

"Sonus' collaboration with leading firewall vendors, such as Palo Alto Networks, to share security intelligence between SBCs and next-generation firewalls not only raises the trust level of UC, but also the security posture of the entire enterprise," noted Brandenburg. "By integrating security intelligence across SBCs, firewalls, and other devices, and brokering it between applications to disseminate it in real-time, Sonus is tapping new opportunities that few competitors are proactively addressing."
