SoftBank expands OpenAI-powered cybersecurity service in Japan - Light Reading

IndustrySafety

SoftBank, the telecom giant that never met a hype train it didn't board, has expanded its OpenAI-powered 'Patching as a Service' to 3,000 companies in Japan. Because nothing says 'trust us with your network' like an AI that occasionally thinks a real vulnerability is just a suggestion. The service uses OpenAI's cybersecurity models to identify vulnerabilities and 'scale deployment' – corporate for 'we'll press the button and hope the lawyers have good insurance.' With each patch, there's a creeping question: who patches the patcher?

The irony is rich. The same OpenAI models powering this service have been shown to generate convincing phishing emails and, in controlled tests, autonomously exploit systems. Yet here they are, entrusted with the digital keys to 3,000 Japanese firms. One imagines the sales pitch: 'Our AI is so smart it can find vulnerabilities – and yes, it can also create new ones, but statistically that's a future problem.' The expansion is a bet on speed over caution, a classic Silicon Valley export that Japan has enthusiastically imported.

SoftBank's move comes as Japan's regulators tiptoe around AI governance. The country's 'Society 5.0' vision warmly embraces tech, but the safety net is still being woven. For now, 3,000 companies are guinea pigs in a grand experiment: can AI-driven security keep pace with AI-driven attacks? If history is any guide, the answer will be 'mostly, until it isn't.' And when it isn't, the slogan 'Patching as a Service' will gain a very different meaning.
