Vonage Trust & Safety Team Mission

Trust & Safety is a shared-service team responsible for the proactive and reactive monitoring of our telecommunication services (messaging and voice traffic) to protect Vonage, its customers, and downstream partners from abuse, fraud, and service degradation. This includes real-time fraud detection, alert response, account blocking, traffic analysis, and investigation of both internal escalations and external carrier disputes.

Operating as a dedicated fraud center of excellence, the team plays a critical role in reducing financial loss, maintaining trusted carrier relationships, and ensuring regulatory alignment. Trust & Safety is also responsible for producing actionable insights that inform network protections, account remediation, and internal fraud policy improvements. The team partners closely with Sales, Security, Legal, Customer Success, Carrier Partnerships, and Engineering to mitigate threats and reduce friction for legitimate traffic.

The team operates 24/7/365, using layered defense mechanisms and tiered response teams to ensure timely intervention and thorough investigation of fraud and abuse patterns across the messaging and voice ecosystem.
