GTT Expands Global Network of DDoS Scrubbing Centers to Combat Rise in Size and Complexity of Cyberattacks

McLean, VA, March 8, 2023

GTT Communications, Inc., a leading global provider of managed network and security services to multinational organizations, has announced the expansion of its network of scrubbing centers in partnership with Corero Network Security, the DDoS protection specialists, spanning four continents globally.

Scrubbing centers receive network traffic and remove any malicious traffic that may be associated with a DDoS attack, to ensure only "scrubbed" safe traffic is delivered to its intended destination. The center in Madrid, Spain, is the latest addition to GTT's global DDoS protection platform, which includes 10 scrubbing centers across Europe, North America, and Asia-Pacific. The GTT platform uses Corero's next-generation DDoS technology, within GTT's global Tier 1 internet protocol backbone, to detect and filter out malicious traffic and complex threats in the network core, in real time.

The new facility in Spain expands the reach of GTT’s scrubbing centers worldwide and strengthens its global network. Madrid, a crucial data center hub with a strategic international position connecting Spain with Latin America, Africa, and Asia-Pacific, serves as an ideal location for the scrubbing center. GTT’s investment will improve network and security capabilities for its customers in the region, mitigating attacks close to the source without impacting traffic latency.

According to Corero, 2022 was another record-setting year for network-based DDoS attacks, which overwhelm the available bandwidth of targeted victims. Corero's security research team highlighted a 39% increase in multi-vector spread spectrum pulse attacks that are designed to circumvent legacy DDoS detection and protection capabilities.

"The expansion of our worldwide DDoS protection platform, integrated with our global Tier 1 internet backbone, creates a formidable defense for our customers against threats to their networks that have been increasing in size and complexity," said James Karimi, CISO and CIO at GTT. "Our newest scrubbing center in Spain is ideally positioned for the huge amounts of internet traffic that flow into this key digital hub, ensuring our high-capacity internet customers are protected from the growing threat of cyberattacks."

"Throughout 2022, DDoS attacks became increasingly sophisticated, while at the same time, the DDoS attack surface expanded," said Ashley Stephenson, CTO at Corero Network Security. "With the number of recorded attacks on the rise and significant shifts in attackers' motives and goals, we are delighted to expand our longstanding partnership with GTT, ensuring their customers have the most robust DDoS defense in place."
