OpenAI, Google, Microsoft and other major companies are urging governments, infrastructure operators and technology providers to strengthen security before more capable AI systems expand the scale and sophistication of cyberattacks.
More than 100 technology, cybersecurity and financial-services companies have signed a public call for a faster, coordinated push to reinforce cyber defenses as artificial intelligence makes attacks easier to scale and potentially more sophisticated.
The signatories include OpenAI, Google, Microsoft and Anthropic, along with companies including Adobe, IBM, Oracle, Visa and Mastercard. Their statement says existing security practices are not sufficient for the coming wave of AI-enabled threats, particularly at organizations running essential services.
The group is calling for companies to fix high-risk weaknesses, reduce excessive access privileges and improve authentication and monitoring. It also urges cybersecurity providers to test defenses against advanced AI capabilities and share threat intelligence and proven remediation methods.
Governments, the statement says, should expand funding and coordination for cyber defense and help give hospitals, water utilities, local governments and other under-resourced critical-infrastructure operators access to defensive AI tools, authorized security testing and practical support.
The companies frame AI as both a growing offensive risk and a potential defensive advantage. Their proposal asks frontier AI developers to provide responsible access to cyber-capable systems, support defenders with funding and training, and build systems that make automated agents more traceable and accountable.
The appeal does not prescribe a single law or regulatory framework. Instead, it centers on shared operational steps: faster patching, stronger access controls, continuous testing, information-sharing and wider deployment of defensive technology.
