Fujitsu Launches 3 Services with Israeli Firm to Support Early Detection of Attack Indicators in Japan

Fujitsu announced on September 25 the launch of security services to support enterprises and organizations in Japan in implementing active cyber defense. The offering comprises three domains: threat intelligence collection from the dark web, visualization of externally exposed IT assets, and proactive investigation of threats lurking within organizational networks. Beyond post-attack response, the services aim to help clients identify risks before damage occurs.

The new services primarily target critical infrastructure operators—including electric power, railway, and financial companies—that fall under Japan's Active Cyber Defense Act, enacted in 2025. With the Japanese government set to begin full-scale operations under the law in October, Fujitsu aims to help strengthen the security foundations of private-sector enterprises.

For two of the three domains—threat intelligence and ASM (Attack Surface Management)—Fujitsu will leverage solutions from KELA (Tokyo, Minato-ku), an Israel-based cyber threat intelligence company with which it has signed a partnership agreement. KELA collects leaked personal information and authentication credentials from the dark web, which is inaccessible through ordinary web searches. Fujitsu analyzes this information to help clients visualize exploitation risks and develop prioritized response plans and countermeasures.

In the ASM domain, Fujitsu continuously tracks customers' IT assets exposed on the internet, identifying vulnerabilities and exploitation risks. By maintaining constant surveillance of external entry points that attackers target first, the service helps organizations identify weaknesses before they become attack vectors.

The third domain is threat hunting, which proactively investigates signs of compromise within organizational networks. Consultants from Fujitsu's business brand "Fujitsu Uvance" and the white-hat hacker team "Uvance Wayfinders" conduct detailed analysis of customer system monitoring data and cloud audit logs. They actively for latent threats that existing monitoring system alerts have failed to detect, as well as evidence of potential internal intrusion. The service also evaluates and verifies the adequacy of the customer's log management practices and audit infrastructure, including whether logs necessary for rapid investigation are being properly collected and retained.

Fujitsu plans to integrate these services with its dedicated cybersecurity organization, the "Cyber Security Nerve Center," launching in October 2026. The company aims to build a framework that provides consistent support from peacetime risk assessment to incident response during emergencies—going beyond post-attack response to help enterprises and organizations establish systems that detect attack indicators and potential risks in advance, preventing damage before it occurs.

Rising Defense Demand Amid AI Proliferation

The services are driven by the accelerating speed and sophistication of cyberattacks amid the expanding use of artificial intelligence (AI). As attack methods grow more sophisticated, the limitations of traditional passive defense—detecting attacks and then responding—have been increasingly highlighted. With the Japanese government set to begin full-scale active cyber defense operations in October, there is an urgent need for critical infrastructure operators in particular to establish systems that detect attacks and their indicators early and prevent damage proactively.

The following table summarizes the three service domains offered by Fujitsu.

Impact on Japan's Security Market

With the enforcement of Japan's Active Cyber Defense Act and the government's operational launch approaching, demand is expected to grow in the Japanese security market for services that support peacetime risk assessment, particularly among critical infrastructure operators. Fujitsu's move to partner with an Israel-based specialist firm to deliver advanced dark web monitoring capabilities to Japanese customers could further intensify competition in this segment.

Dark web information gathering, in particular, requires a high degree of specialization and has been considered difficult for Japanese companies to handle independently. Partnerships with overseas threat intelligence specialists like KELA represent a practical option for major Japanese IT firms seeking to enhance the effectiveness of their security services, and this approach could spread to other providers going forward.

Fujitsu has indicated it will strengthen its service delivery framework through integration with the dedicated cybersecurity organization launching in October. The company's positioning of active cyber defense as a pillar of business growth is clear, and its efforts to expand its customer base—centered on critical infrastructure operators—are expected to accelerate.
