SIP Security

Conventional security devices like firewalls can’t protect real-time communications traffic.  Ribbon's SIP security solution is specifically designed to secure VoIP and IP multimedia sessions and to safeguard the enterprise network against denial of service attacks, theft, and fraud. Ribbon's unique adaptive security capabilities intelligently analyze traffic flows in real-time, identifying and blocking threats before they impact performance or availability.

Using Session Border Controllers in Unified Communications Security

Using intelligent session border controllers (SBCs) installed at the edge of the enterprise network, the Ribbon solution secures SIP sessions and protects IP communications infrastructure such as application servers, media servers, and media gateways.  Ribbon’s flexible and extensive SBC portfolio offers a choice in element size and functionality to meet diverse scale and deployment requirements.
