Radware expands global defense capacity as DDoS attacks grow harder to contain

Radware has expanded the mitigation capacity of its global cloud security network, doubling it from 15 terabits per second to 30 terabits per second, as distributed denial of service attacks continue to increase in both scale and sophistication. The upgrade spans all of the company’s cloud security centers and reflects a changing threat environment that increasingly challenges traditional defense models.

The expansion follows a sharp rise in attack activity. Radware reported an 85 percent increase in network-level DDoS attacks during the first half of 2025 compared with the same period last year. At the same time, attackers are relying less on sheer volume alone. Instead, many campaigns now combine high-bandwidth floods with targeted application-layer techniques designed to overwhelm services without obvious spikes in traffic.

Radware said the expanded network relies on the latest generation of its DefencePro X platform, which emphasizes automated response and faster mitigation during high-intensity events. According to the company, modern DDoS campaigns often blend network saturation with HTTPS floods and other request-based attacks. These approaches aim to exhaust application resources rather than simply clogging bandwidth.

Roy Zisapel, president and chief executive officer of Radware, said the nature of attacks continues to evolve as adversaries adopt automation and AI-driven tools. He pointed out that today’s big, complex attacks need defenses that can move fast but still let real users in without a hitch.

Radware isn’t just throwing more resources at the problem. They’re all about accuracy. Its AI-based web DDoS protections target HTTPS flood attacks that can exceed tens of millions of requests per second. The goal, the company said, is to stop malicious traffic while avoiding unnecessary disruption for real users during mitigation.

Geographic distribution also plays a role in the strategy. Radware keeps stopping attacks as close to where they start as possible. This setup lets them react quickly and keeps apps running smoothly for everyone around. It also fits organizations that have tough rules about keeping their data local.

In 2025, Radware expanded even further and launched new cloud security centers in Bogotá, Lima, Mumbai, Singapore, and Tel Aviv. Now they’ve got 65 centers around the world, helping customers who run their operations across different clouds and hybrid setups.

Attacks are getting smarter and more tangled, and Radware’s latest move really shows where the industry’s headed. These days, having more capacity, smarter automation, and a bigger local presence really sets security providers apart when they’re up against massive DDoS threats.
