Industry that built the problem offers to sell you the solution

OpenAI has gathered more than 100 of the world's biggest tech and infosec companies to warn that cyber defense is in trouble - a reassuring development given quite a few of them helped build the technology involved. The open letter has more than 100 names attached to it, including many of the companies with the most to gain – or lose – from what happens next. OpenAI, Anthropic, Google and Microsoft are among the AI builders warning about increasingly capable AI attacks, while security heavyweights including Cloudflare, CrowdStrike, Fortinet, and Palo Alto Networks have also signed on. AWS, IBM, Oracle and Cisco are there too, alongside banks, consultancies and other companies whose businesses depend on keeping an increasingly messy technology stack running. Together, they have reached a troubling conclusion: the current approach to cybersecurity isn't working. "We have a limited window to strengthen cyber defenses," the letter warns, predicting that AI-enabled attacks will become "far more widespread and sophisticated" in the coming months as models become more capable. Hospitals, water treatment plants and internet infrastructure are singled out as being at risk. It's an interesting warning given who's making it. Some of the signatories are racing to build ever more capable AI systems, while others make billions selling the cloud services, enterprise software and security tools that are supposed to keep attackers at bay. Still, the underlying problem is real enough. The letter points to old vulnerabilities, unpatched software, misconfigurations and weak authentication as problems that have been piling up for years, particularly across critical infrastructure where security teams are often short on money and staff. Their proposed solution is, inevitably, more AI. The letter calls for cyber-capable models to be put into the hands of more defenders, with cheaper models handling security work at scale and frontier systems reserved for harder problems. Security vendors should continuously test their defenses against frontier AI capabilities, share threat intelligence and help critical infrastructure operators deploy AI-powered defenses. Governments, meanwhile, are asked to fund cybersecurity for essential services, expand trusted-access programs and give hospitals, water utilities and local governments access to capable defensive AI. Companies developing frontier models have their own homework assignment. They should provide "responsible model access, significant funding, training, and hands-on support," particularly to under-resourced critical infrastructure operators, while investing in testing, vulnerability disclosure and tools that make AI agents traceable. What the letter doesn't include is any figure for that "significant funding," or any deadlines or firm commitments from the companies signing it. For now, they're being asked to bring the "full weight of their technology, resources, and expertise" to the problem. It's quite a message from a group that includes some of the biggest names in cloud, enterprise software, and cybersecurity. When more than 100 companies agree that "status quo security won't be enough," it's worth remembering that many of them have been selling that status quo for years. There is some urgency behind all this. AI agents have already been shown finding and exploiting vulnerabilities on their own, while AI-generated exploit code has started turning up in attacks against critical infrastructure. As the models improve, the fear is that those capabilities become cheaper and available to a lot more attackers. That's the "defenders' window" the signatories want to seize: use AI to shore up defenses before the offensive side gets much easier. So, after years of selling organizations cloud services, security software and, more recently, AI, the industry has settled on a fix for the looming AI security problem: better cybersecurity, more resources and more AI. Who will pay for it remains rather less clear. ®
