To securely deliver and monitor VoIP services for anomalous behavior, a new collective security approach is now available that leverages a proven in-depth security defense model via the RedShift Uniﬁed Communication Threat Management (UCTM) Platform. The UCTM platform intelligently combines SIP Security, Threat Intelligence Analytics and Fraud Detection to give operators real-time, context-driven visibility into unauthorized activities and mitigate threats including Denial of Service (DoS), Botnet attacks and Robocalls throughout their VoIP network.
