Block Communications Commercial Telecom Teams Up with Corero to Reinforce Network Security

The integrated communications provider forms strategic partnership to offer first line of defense against DDoS attacks to customers.

TOLEDO, OHIO, US –December 1, 2015 – Block Communications commercial telecommunications divisions, Telesystem (www.telesystem.us), and Line Systems (LSI) (www.linesystems.com), announce the joint alliance with Corero Network Security, a leading provider of Distributed Denial of Service (DDoS) defense solutions.

Corero delivers real-time DDoS protection via the SmartWall® Threat Defense System (TDS) with SecureWatch® Analytics, a connected suite of security applications that delivers comprehensive DDoS defense services. DDoS attacks are attempts to make online service unavailable by overwhelming it with traffic from multiple sources. The attacks, according to Eveland Morris, Director of Engineering at Line Systems, are extremely difficult to defend against. “Identifying a single assailant against a backdrop of valid users to your network is manageable with adequate monitoring tools, but when hundreds or thousands of attacks are bombarding you at once it takes a significant amount of time, money and resources, usually against diminishing bandwidth, to stop the attack,” explains Morris.

Telesystem owns and operates two data centers with seven Tier 1 interconnects which provide all of the Internet bandwidth for the company’s customers. The solution provides increased visibility into attack traffic on Tier 1 links that promotes high levels of customer confidence in Telesystem’s service. "We have received alerts from the Corero SOC team to let us know about events that were going on. When a major attack does come in, Corero gives us a courtesy notice to tell us it's already being blocked or in mitigation. It has minimized the negative impact to our service availability. Corero's solution does exactly what we hoped it would do," says Stephen Clark, Director of IP Networks at Telesystem.

Line Systems’ IP-based private network is supported by multiple geographically diverse data centers as well as four Tier 1 interconnections.  This partnership and the alignment it represents across Telco business units with Corero, delivers equally reliable security services to support LSI’s network infrastructure and in turn further protect end users. The partnership was attractive as it was a complete, plug-and-play defense solution that really puts us at the front of the security curve. The solution not only improves protection against DDoS attacks but the monitoring environment further strengthens our response intervals,” states Warren Reyburn, Executive Vice President at LSI.

The Corero SmartWall TDS is now available and actively mitigating DDoS attacks for the for the joint customer base. Looking toward the future, Telesystem and Line Systems plan to use the new DDoS mitigation capabilities to create new service offerings that would benefit customers with enhanced service level agreements supported by further secured Core networks.
