Krishna Kurapati co-founded Sipera Systems raised $10 million in its series C funding. Led by Duchossois Technology Partners, the funding brings Sipera’s total amount raised to $29.5 million. The round was led with the participation of existing investors Austin Ventures, Sequoia Capital and STAR Ventures.

Headquartered in Richardson, TX, Sipera Systems is a provider of comprehensive VoIP security solutions. Through this funding the company is aiming to deliver more advanced real-time VoIP/UC security capabilities for the Sipera IPCS product line; and increase the VoIP vulnerability consulting services from Sipera VIPER (Voice over IP Exploitation Research) Lab. At Sipera VIPER Lab thousands of researchers are working on identifying potential security threats and vulnerabilities that can be launched against SIP, IMS, and UMA networks.

“Since we first introduced the Sipera IPCS 310 in 2006, we’ve expanded the IPCS product line to enable a broader range of large enterprises and service providers to better secure VoIP and unified communications. The addition of Sipera VIPER Services complements our product offering by helping our customers assess and manage the risk associated with their VoIP/UC networks. Our VIPER consultants leverage the industry’s most extensive database of VoIP/UC vulnerabilities, discovered by the Sipera VIPER Lab research team,” said Seshu Madhavapeddy, Sipera President and CEO. “This funding will allow us to establish new global partnerships, further enhance our comprehensive security offering, and create a robust real-time communications risk management practice by expanding our VIPER Lab research and consulting services.”
