Frequently Asked Question!

What is Enterprise Voice Security?

Enterprise Voice Security is the practice of protecting enterprise phone systems, contact centers, and voice infrastructure from threats such as vishing (voice phishing), scam calls, robocalls, toll fraud, TDoS attacks, and impersonation fraud.
Unlike traditional IT security, voice security operates at the telecom and SBC (Session Border Controller) layer, where real-time call threats originate.

What is vishing and how does it impact enterprises?

Vishing (voice phishing) is a fraud technique where attackers impersonate customers, vendors, executives, or regulators over phone calls.
Common enterprise vishing attacks include:

  • Customer impersonation to access accounts

  • Vendor payment redirection scams

  • Executive impersonation (“CEO fraud”)

  • Fake compliance or auditor calls

Traditional call blocking tools cannot detect these attacks.

What threats does Assertion Secure Voice protect against?

Assertion Secure Voice protects enterprises from:

  • Vishing & voice phishing

  • Scam & spam calls

  • Robocalls & Voice CAPTCHA bypass attempts

  • Toll fraud

  • TDoS (Telephony Denial of Service)

  • Customer impersonation

  • Vendor impersonation

  • Regulator & auditor impersonation

  • Compliance violations on outbound calls

Can Assertion Secure Voice protect healthcare and insurance call centers?

Yes. Assertion Secure Voice is highly effective in:

  • Hospitals (protecting patient room phones from scam calls)

  • Health insurers (detecting CMS auditor and regulator calls in real time)

This helps organizations:

  • Prevent patient scams

  • Improve audit handling

  • Avoid penalties

  • Protect brand trust

Is Assertion Secure Voice compliant with enterprise security standards?

Yes. Assertion Secure Voice aligns with enterprise security expectations, including:

  • Privacy-first architecture

  • Secure deployment models

  • Enterprise-grade access controls

Why are scam calls reaching agents even with SBCs in place?

SBCs focus on call routing and availability, not real time threat detection.

Attacker technology has been evolving and breaking through traditional security features of SBCs.

Without AI-driven voice security layered on top, SBCs allow malicious calls through easily.

How can contact centers prove ROI for voice security investments?

ROI is measured through:

  • Reduced fraud losses

  • Fewer scam calls reaching agents

  • Lower call abandonment

  • Improved SLA adherence

  • Reduced operational disruption

Blocked attacks translate directly into cost savings.
