Provider networks continue to experience growth in traffic, which raises costs, without corresponding growth in revenues.

The internet as we know it today did not yet exist; however, ARPANET, its predecessor network, was the exclusive domain of a small group of academics and researchers, so no one gave much thought to security.

The Domain Name System – the DNS – is the foundation of the internet. Beyond connecting IP addresses with web requests, DNS provides the basis for both the detection of and protection from global cyberthreats before they reach an organization’s corporate network resources —particularly given that more than 90% of malware uses DNS for command and control. This presents a tremendous opportunity for service providers to utilize their DNS infrastructure to provide security services to their business customers, which have a tremendous need for stronger, more proactive cyber protection.
