Sipera Systems, Top VoIP Company 2008: FierceVoIP, Fierce 15
Sipera Systems
Where it's based: Richardson, Texas
When it was founded: 2003
Website: www.sipera.com
Why it's Fierce: Proactive VoIP security testing and vulnerability assessment is something Fierce to our professionally paranoid hearts, so Sipera would win consideration simply for its in-house VIPER lab. However, Sipera has moved beyond simply flogging the latest VoIP threats to incorporate unified communications into its assessments and security appliances. Its latest product release offers advanced security for SIP trunking, better integration into SIP trunk provider services and adding additional SBC functionality. We expect to see more out of Sipera in the months to come.
