Worried about fraudulent calls?

Learn why it’s critical to build and implement a robust voice security strategy.


There are a variety of voice security threats, including the following:

  • Vishing: The fraudulent act of making phone calls or leaving voice messages that deceive victims and companies into revealing sensitive information

  • Deepfake: A synthetic media technique that uses artificial intelligence (AI) to alter or create content, often videos and audio recordings, to make the content appear as if it is genuine

  • Spoofing: Involves modifying call header information to make a call appear to come from a different phone number or location. While there are legitimate applications of spoofing, it is often an aspect of fraudulent calls. Being able to detect when calls into your environment are spoofed is an important step in detecting incoming fraud

  • Robocalling: Leverages auto-dialing capabilities to generate large volumes of traffic. Like spoofing, it can be used legitimately, but it is often used as a vector for launching volume-based attacks against enterprises and their voice infrastructure

Verizon has an array of voice security solutions to help protect you from these different attack types.

Layered controls are nothing new in combating security threats, and voice security is no different. Verizon offers an array of tools that look at voice security threats from multiple layers. 

Initially, at the network level, Verizon has multiple tools that combat bad traffic and filter out obvious threats. In addition to network-level protections, enterprises should also look at how traffic comes into their telephony infrastructure and poses threats that are unique to their business and can't be filtered at the network level. This is where enterprise voice firewalls come into play.

Finally, specific solutions and applications, such as contact centers, have high volumes of voice traffic and are major targets for fraud. Therefore, additional application-specific tools targeted at anti-fraud and authentication can be deployed to help stop fraud losses.

All of the above are types of known social engineering threats that continue to grow in attack volume. In many cases, AI makes these threats harder to detect and prevent. Verizon provides offerings to help you close security gaps in your ecosystem and that can help protect you against these and other voice security threats.

Phishing: Spam email sent to people or organizations to try to trick them into divulging confidential information, such as usernames and passwords, or clicking on a malicious link

Vishing: The fraudulent act of making phone calls or leaving voice messages that deceive victims and companies into revealing sensitive information

Smishing: Spam text messages sent by attackers to trick individuals or organizations into sharing sensitive information, such as passwords

Quishing: QR Code phishing, getting someone to scan a QR Code that will take them to a malicious website that will try to get sensitive information or download malware
