Securing Carrier Voice Networks Becoming a Priority in the Age of VoIP

When the data networks of prominent companies like Target and Home Depot are exposed to hacking and breaches, the news typically makes headlines. But attacks on voice networks are also on the rise and many carriers are struggling to combat this newer but serious type of security breach.


Redshift Networks targets the carrier market with its suite of voice security and analytics solutions, with a focus on securing cloud-based VoIP, UC and video networks. TMC Executive Editor Paula Bernier got a chance to speak to Amitava Mukherjee, president, CEO and co-founder of Redshift, at the recent ITEXPO Florida 2016 event.

“You’d be surprised to hear that some of the top carriers in the world are seeing so many attacks in the voice realm, when normally we hear about data attacks, Trojans and botnets,” said Mukherjee. “But voice is a new realm of attack.”

The company’s carrier customers use Redshift solutions to protect their internal infrastructure and are also starting to market the offerings to their own customers as a value-added solution. Mukherjee said the shift toward VoIP has brought about an increase in SIP trunking and softswitches and session border controllers (SBCs) can only go so far when it comes to securing this new breed of voice networks.

“It’s become a whole new universe of access devices to voice communications, and with that realm of course the threat matrix and the threat vector increases tremendously,” he added.

Redshift’s core infrastructure UCTM solution monitors and manages security for both network elements and traffic via an appliance-based system. The offering combats more than 40,000 threat signatures and includes an adaptive dynamic behavioral learning engine for identifying abnormal traffic in real time. One of the biggest benefits for carriers is that the solution does not impact network performance and in fact protects against threats and breaches that could significantly degrade service levels.

The company, which already works with NEC as a reseller in Japan, has a number of key vendor and reseller partnerships in the pipeline, according to Mukherjee. Redshift also plans to move into the MSP realm, forging channel partnerships that will enable their offerings to be marketed as managed and value-added services.
