Nearly 130 organizations spanning cybersecurity, cloud computing, finance and other industries have signed an open letter calling for a coordinated, global surge in cyber defense as AI makes attacks more widespread and sophisticated.
Signatories include Anthropic, Microsoft, Google, Cisco, Check Point, Cloudflare, CrowdStrike, IBM, Oracle and OpenAI, which is leading the effort.
The letter warns that AI-enabled attacks will become significantly more capable in the coming months, putting hospitals, water treatment plants and internet infrastructure at increasing risk. However, the same AI advances are giving defenders new ways to fix security weaknesses, and acting quickly could make a lasting difference.
Three principles anchor the collective response proposed by the initiative. One of them is that longstanding bugs, misconfigurations, weak authentication and other technical debt mean status quo security will no longer be enough.
The second refers to AI extending specialist security skills to more defenders and making shared knowledge and verified fixes more broadly useful. The last principle emphasizes the need for a global, coordinated response as cyber capabilities advance across many organizations.
Every organization is asked to treat cyber defense as an immediate leadership priority, fix the highest-risk weaknesses first, raise the security bar for what they build and buy, and apply compensating controls where systems can’t be patched without disrupting essential services.
Cybersecurity companies and technology partners are called on to test defenses continuously against frontier-level AI capabilities, make AI-powered protection accessible to critical infrastructure operators with limited budgets, and share threat intelligence and playbooks that have been verified to actually work.
