Nationwide Processing, which provides outsourced mortgage production services to the lending industry, has selected eTechHelp and Ingate® Systems to deploy Ingate SIParator® Enterprise Session Border Controllers (E-SBCs) to secure their SIP trunking service and their network from ongoing toll fraud and hacker attacks.

The Ingate SIParators also enable remote NAT/firewall traversal (Far-End Network Address Translation) making it possible for Nationwide Processing’s 60 at-home center agents to access SIP trunking services through Nationwide’s IP PBX, which is located in a Tier III data center. Although this IP PBX had a second IP Interface that could be connected to a public IP address, it was not hardened for such usage. Ingate provided both IP-level and SIP-level security mechanisms.

Initially connected directly to the Internet, Nationwide Processing’s IP PBX continuously registered brute force registrations, as well as toll fraud, Denial of Service (DoS) and SIPVicious attacks. These attacks flooded the PBX with thousands of requests per second, freezing the PBX and blocking all calls to and from the call center agents. Working with eTechHelp they installed an Ingate SIParator 19 and SIParator 21 at the data center. This placed the PBX behind the Ingate E-SBC, which blocked all attacks.

“We were getting hammered by hackers. Ingate eliminated the entire issue. We are now clean and running issue-free,” said Guru Amrit Khalsa, President, Nationwide Processing. “eTechHelp has been the technical lead for the design, implementation and maintenance of our in-house, multinational VoIP phone system. I am impressed with their willingness to own a problem and then coordinate multiple vendors to solve it. They can handle whatever comes up.”

The Ingate SIParator is a powerful and cost-effective E-SBC for SIP connectivity, security and interoperability, such as connecting PBXs and UC solutions to SIP trunking service providers. SIParators offer enhanced security with TLS (Transport Layer Security) for secure SIP signaling, and SRTP (Secure Real-time Transport Protocol) for encrypted voice and video. They feature authentication and replay protection to shield users from eavesdroppers, hackers and spoofers and protect against theft of service. Here, SIP IDS/IPS (Intrusion Detection System/Intrusion Prevention System) worked in tandem with Ingate’s other security technologies, further strengthening security for VoIP, SIP trunking, UC and other SIP applications.
