SoftBank and OpenAI Launch AI-Powered Cybersecurity Service to Protect Japan's Critical Infrastructure
June 16, 2026
SoftBank and OpenAI launched an OpenAI-powered patching and vulnerability assessment service in Tokyo to defend Japan’s critical infrastructure against cyberattacks, starting with a rollout to about 100 firms in finance and telecommunications.
OpenAI’s involvement featured a video message from CEO Sam Altman due to personal circumstances, with OpenAI Chief Researcher Mark Chen presenting in person.
No price was announced for the rollout, but attendees were invited to apply for a free diagnostic assessment of their systems.
Analysts view SMCI as potentially undervalued, recommending further analysis before investment decisions.
SMCI’s GF Score shows Growth at 10/10 and Profitability at 8/10, with moderate Financial Strength (6/10), low Valuation (2/10), and solid Momentum (7/10).
There was no monetary value disclosed for the service rollout.
Insider trading over the past three months shows no reported buying or selling by SMCI insiders, suggesting stable sentiment.
The initial rollout targets about 100 firms, including operators of critical social infrastructure in finance and telecommunications.
A publisher disclaimer notes the content reflects the author’s opinions and is not investment advice.
The ultimate test is whether identified vulnerabilities are closed and the rollout proves effective in safeguarding critical infrastructure.
The service conducts AI-assisted vulnerability assessments and remediation planning, but does not automatically apply patches; human teams prioritize and execute fixes.
Despite the term “automation,” the offering is more accurately an AI-assisted audit with a remediation plan requiring human execution.
