Tech Giants Unite on AI Cyber Defense
Over 100 tech companies sign open letter urging collective action against AI-enabled cyber attacks.

The update
More than 100 companies across the tech, AI, finance, and cybersecurity sectors have signed an open letter titled “A call for collective action on cyber defense.” Signatories include OpenAI, Google, Anthropic, Microsoft, AWS, and CrowdStrike. The letter warns that AI-enabled cyber attacks will become far more widespread and sophisticated in the coming months. It calls on organizations, governments, and the tech industry to adopt new security measures, including building observability tools, ensuring agentic identities are traceable, and sharing best practices.
Why it matters
This marks a coordinated industry effort to address a specific, emerging threat: the use of advanced AI models to power more sophisticated cyber attacks. The letter highlights the risk to critical infrastructure, such as hospitals and water treatment plants, and suggests that current security measures may be insufficient against these new threats.
What to watch
Watch for the specific technical proposals outlined in the letter and how governments respond to the call for collaboration. The practical implementation of these collective measures remains to be seen.
