Early Authentication Helps Strengthen Contact Center Fraud Detection [Infographic]

Every 46 seconds, a fraud attack occurs in a contact center, according to the 2025 Voice Intelligence and Security Report. Without fast detection, these attacks can lead to financial losses, reputational damage, and eroded customer trust. The key to effective contact center fraud detection is identifying threats as early as possible—ideally before the fraudster ever has a chance to speak.

Most authentication methods wait for a voice and require the caller to answer questions or provide information. That delay can create an opening for bad actors. Phoneprinting® analysis changes the approach by starting call authentication the moment the call connects. In just the first 10 seconds, it can analyze device and non-speaker audio signals to help identify high-risk calls before they escalate.

Why early call authentication matters for contact center fraud detection

By shifting authentication to the very start of the call, contact centers can:

Reduce fraud exposure by flagging risky devices and suspicious call patterns in real time

Improve customer experience by speeding up service for trusted callers

Authenticate without needing voice, so even silent or manipulated calls can be assessed

How trust is established in the first 10 seconds

• Passive device profiling begins immediately
  More than 1,300 non-speaker audio signals—such as packet loss, jitter, and codec behavior—are analyzed from the time the call connects
• A unique PhoneprintⓇ signature is generated
  This device analysis helps detect anonymizers, VoIP manipulation, and unusual call patterns linked to fraud
• Call risk score is generated before a word is spoken
  Based on the score, calls can be routed to the right path

The cost of outdated authentication

Traditional authentication methods can slow down the process for legitimate customers and can miss early fraud signals. By using technology with PhoneprintingⓇ analysis and early call authentication as part of your contact center security strategy, you can gain both speed and accuracy, helping to protect your organization while streamlining service.
