Call Security & Trust

What We Do

Call security stops attacks and malicious calls.

Our call filtering solutions filter unwanted and malicious calls out of your network, protecting you and your customers from call attacks.

Auto-authentication verifies calls and detects outbound call spoofing.

We verify and authenticate every call, before your agents pick up the phone. Our smart auto-verification solution analyzes thousands of call and network details and real-time carrier network metadata to orchestrate your very best, lowest cost call-authentication and fraud inspection decisions.
