Hitachi & Radware launch AI cloud defence against DDoS attacks

Hitachi Solutions and Radware have jointly announced the launch of a new cloud-based service designed to protect organisations in Japan from a surge in web-based distributed denial-of-service (DDoS) attacks. The Radware Cloud Application Protection Service applies artificial intelligence to rapidly detect and mitigate sophisticated attacks targeting business applications and APIs.

Threat landscape

Organisations across Japan have seen a significant increase in DDoS activity since late 2024. High-profile cyber incidents, including critical disruptions to transportation systems, have prompted government warnings. Attackers have been employing more varied methods, focusing on application layers and encrypted traffic, making threats harder to identify and block before they cause downtime.

AI-powered defence

The new service uses artificial intelligence algorithms to identify zero-day web DDoS attacks in real time. The technology generates precise defence signatures within seconds, adjusting controls as attack patterns change. This allows security teams to differentiate between legitimate and malicious traffic, minimising the risk of inadvertently blocking genuine users while maintaining protection against cyber threats.

The service supports mitigation for a broad range of threat types, including network-based, volumetric, and encrypted traffic attacks. Radware's system automatically reviews and adjusts policies to ease operational burdens during an incident. Regular support is also offered for policy review, helping organisations maintain an effective security posture without excessive manual intervention.

Cloud infrastructure

Radware operates 24 cloud security centres globally. This geographic distribution helps to intercept and neutralise attacks closer to their point of origin, reducing latency and maintaining service performance for end users. The infrastructure also supports load-balancing, further ensuring continuity during an incident.

Japanese market needs

"The cybersecurity landscape across Japan is reaching a critical inflection point. 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," said Yaniv Hoffman, Vice President Sales, APAC, Radware. "Radware is proud to partner with leading Japanese companies such as Hitachi to protect enterprises and their end users."

Resilience strategy

In addition to the cloud-based service, Hitachi Solutions will offer consulting services from white-hat hackers, incident response support and operational assistance as part of its Cyber Resilience Solutions portfolio. The company will also promote Radware's DefencePro X hardware DDoS protection platforms, aiming to provide a layered approach from prevention through to recovery.

Rising attack volume

Radware's latest Global Threat Analysis Report showed a 550% increase in reported DDoS attacks compared with figures from 2023. Attackers continue to adopt more sophisticated tactics, including stealthier web DDoS strategies and use of encrypted channels to evade traditional defences. The increase in advanced attacks, coupled with incidents affecting critical infrastructure, has made business continuity planning and automated defence a priority for organisations in Japan.

Hitachi Solutions will position the new service as part of its wider Cyber Resilience Solutions offering. The goal is to enhance real-time detection, streamline operational response to cyber attacks, and help businesses strengthen their ability to continue operating during security incidents.
