TLDRs:
- SoftBank and OpenAI introduced AI-powered cybersecurity services for 3,000 Japanese enterprises.
- New platform identifies vulnerabilities and recommends fixes using advanced AI analysis.
- Around 1,000 specialists will support deployment and cybersecurity consulting services.
- Companies also plan AI-driven legacy software modernization and cloud migration assistance.
SoftBank Corp. is expanding its artificial intelligence ambitions by launching a new enterprise cybersecurity initiative with OpenAI, targeting thousands of businesses across Japan that operate critical infrastructure.
The service, unveiled on July 14 through SB OAI Japan GK, the 50-50 joint venture established by SoftBank and OpenAI, will initially be made available to approximately 3,000 eligible organizations. The offering is designed to help companies strengthen their cyber defenses by using AI to identify software weaknesses, recommend corrective actions, and streamline security maintenance.
The announcement represents another step in SoftBank’s strategy to integrate generative AI into enterprise operations while addressing the growing cybersecurity challenges facing businesses that manage essential services.
AI-Powered Vulnerability Detection
The newly introduced platform combines artificial intelligence with cybersecurity analysis to automate several time-consuming security processes.
Organizations using the service will receive detailed vulnerability assessments that examine software for potential security flaws. The system also generates diagnostic reports outlining identified risks, provides remediation recommendations, and assists customers with deploying software patches designed to eliminate known vulnerabilities.
According to SoftBank and SB OAI Japan, early assessments conducted on a select group of customers demonstrated the scale of the security challenge facing enterprise software. The companies said their analysis uncovered an average of roughly 280 potential vulnerabilities for every 10 million lines of source code reviewed.
Of those detected issues, approximately one-quarter were classified as high-risk vulnerabilities, highlighting the importance of continuous monitoring and proactive remediation for organizations operating critical systems.
By automating much of the detection and reporting process, the companies aim to help businesses reduce the time required to identify and resolve security threats before they can be exploited.
Dedicated Cyber Defense Team
To support the rollout, SoftBank plans to establish an Enterprise AI Cyber Defense Office beginning July 16.
The new organization will work alongside SB OAI Japan to provide implementation support and cybersecurity consulting for participating businesses. Together, the companies intend to assign approximately 1,000 personnel to help customers deploy the platform, interpret assessment results, and strengthen their overall security posture.
The large-scale staffing commitment underscores SoftBank’s intention to position AI-assisted cybersecurity as a core enterprise offering rather than simply another software product.
The consulting component is expected to help organizations prioritize vulnerabilities based on severity, implement recommended fixes, and improve long-term cyber resilience through ongoing assessments.
Beyond Cybersecurity Services
The partnership also extends beyond vulnerability detection.
SoftBank and OpenAI said they plan to introduce a separate modernization service aimed at organizations running aging software systems. The initiative will focus on refactoring existing code, updating applications to newer programming languages, and helping businesses migrate selected legacy on-premises environments to cloud infrastructure.
Many large enterprises continue to rely on decades-old software that is expensive to maintain and increasingly difficult to secure. Modernizing these systems can reduce operational complexity while improving compatibility with newer cybersecurity technologies and AI-powered development tools.
The modernization effort complements the cybersecurity platform by addressing not only existing vulnerabilities but also the underlying technical debt that often contributes to security risks.
The launch also highlights the expanding relationship between SoftBank and OpenAI as both companies seek to accelerate enterprise adoption of artificial intelligence across Japan. Rather than limiting AI to productivity applications, the partnership is increasingly focusing on infrastructure-level services that can enhance software quality, operational efficiency, and cyber resilience.
As cyber threats continue to become more sophisticated, businesses are looking for technologies capable of analyzing massive codebases more quickly than traditional manual reviews. AI-powered security tools are emerging as an important component of modern software development and risk management strategies.
For SoftBank, the initiative reinforces its broader investment in enterprise AI while creating another commercial use case for generative AI within one of Japan’s largest technology ecosystems. If adopted widely, the service could help critical infrastructure operators improve software security, modernize legacy applications, and reduce exposure to increasingly complex cyber threats.
