Network Protection

Protecting Your Infrastructure and Your Subscribers

Broadband providers invest heavily in their networks, enabling subscribers to enjoy rich and interactive activities like streaming media, online gaming, VoIP, content acquisition and content distribution. Increasingly, subscribers rely on these applications as valued components of daily life.

A minority of Internet users have found other ways to put the network to work: launching debilitating attacks on networks and specific targets, delivering billions of unwanted e-mails and hijacking the computers of other subscribers.

The cost of this misuse is staggering. Service providers are faced with the financial burdens created by malicious use of their network resources, including:

• Support calls resulting from symptoms of infection and attack
• Subscriber churn as a result of e-mail and IP blacklisting
• Operational expenses to protect and restore network services
• Campaigns to contact and educate infected subscribers

Most network operators employ firewalls, intrusion-prevention systems and anti-virus software as part of an overall network security strategy. These technologies, however, are not designed to address the requirement for immediate response or the specific security issues facing today’s service providers at the scale of modern networks.

Sandvine Understands Service Providers

By working exclusively with Internet service providers to understand the security issues they face, Sandvine has designed a security product that is ideally suited to identifying and mitigating the unique set of threats that exist on broadband networks. Sandvine's award-winning Network Protection product recognizes the symptoms of infection in real-time and enables proactive intervention, reducing the operational expenses associated with malicious traffic and ensuring subscribers the best possible quality of experience. It’s simply better broadband!

A defense strategy built on Sandvine's Policy Traffic Switch (PTS) scales to any network size and any number of asymmetric links, allowing the solution to focus on the tasks at hand:

• Identifying and blocking sources of outbound e-mail spam
• Preventing worms from spreading on the network
• Detecting and blocking Denial of Service (DoS) attacks

Furthermore, because subscriber-awareness is native to Sandvine’s PTS, customers who have fallen victim to malicious software can be identified. When coupled with Sandvine's Web-redirection capabilities, this complete solution enables targeted communication with subscribers through a branded Web portal. The instructions provided on the Web portal describe how subscribers can cleanse their PCs and continue to enjoy a quality Internet experience.
