Hitachi Solutions teamed with application security firm Radware in a deal that will have Hitachi’s IT services arm offer Radware’s cloud application protection service, a cloud-based solution designed to detect distributed-denial-of-service (DDoS) attacks that target applications and APIs.

Application layers are notoriously difficult to shore up from DDoS attacks. Hits on the application layer create far more damage from botnets using less total bandwidth because they are designed to exhaust specific server resources like CPU and memory rather than the network. Such requests often appear genuine, mimicking legitimate user behavior and thereby making it extremely difficult for traditional defenses to determine whether traffic is in fact benign.

AI-based algorithms baked into Radware’s cloud-based service are capable of generating defense signatures and automatically adjusting thresholds during potential attacks in order to distinguish between normal and abnormal traffic.

The system is capable of reducing operational burden without blocking legitimate traffic, helping to prevent issues while avoiding disruptions to user services.

Hitachi Solutions’ Radware offering comes as DDoS attacks are getting increasingly larger and more complex.

In 2025 alone, Cloudflare witnessed three record-breaking DDoS attacks, each one setting a new peak size record for the vendor. The largest of which was recorded in September and peaked at 22.2 Tb/s and 10.6 billion packets per second (PPS).

Figures from Nexusguard suggested that the average DDoS attack size is surging, rising by 69% this year. Beyond those record-breaking attacks, Cloudflare said it has seen soaring DDoS attempts, noting a 44% increase in the second quarter of 2025 alone.

Upon announcing their partnership, Radware and Hitachi Solutions said the target market of Japan hasn’t been immune to the DDoS rise.

Carpet-bomb DDoS attacks – in which threat actors flood IP addresses within a specific network – caused havoc upon Japanese businesses at the end of 2024, impacting Japan Airlines, local banking giants including MUFG and Mizuho, as well as carrier NTT DoCoMo.

The pair positions Radware’s offering as a way to potentially stop attacks before they disrupt services.

“The cybersecurity landscape across Japan is reaching a critical inflection point," Yaniv Hoffman, Radware’s sales VP for APAC, explained. “With digital transformation accelerating, organizations are facing not just more frequent attacks, but also more sophisticated ones that target applications, APIs, and data at scale. Businesses need proactive, AI-driven defenses that align with the unique challenges and opportunities of this region.”
