CallTower has launched an enterprise-grade voice spam blocking solution, powered by Mutare.
CallTower’s solution secures voice traffic at the network edge, intercepting and neutralizing threats before they reach employees, systems, or sensitive data. This approach positions voice as a protected layer of enterprise infrastructure that sits on par with email and network security.
The platform delivers a multi-layered defense against both known and emerging threats by combining STIR/SHAKEN caller authentication with real-time threat intelligence to verify identities and block malicious calls before they reach the enterprise. To counter more sophisticated and evasive tactics, it also introduces Voice CAPTCHA, a solution designed to challenge suspicious callers in real time.
Administrators gain centralized control through a unified dashboard to set policies, monitor live traffic, and analyze call activity, while seamless integration with existing security ecosystems enables real-time voice telemetry and logging into SIEM platforms.
Organizations can also begin in a monitor-only mode to baseline traffic and refine rules before enabling full enforcement, an approach that eliminates unwanted and malicious calls to reclaim employee time, reduce operational friction, and mitigate financial and reputational risk, with a built-in productivity calculator to quantify measurable cost savings and efficiency gains.
