Nvidia joins Microsoft and SpaceX in open-source AI security alliance
Nvidia backed a 30-plus-company security alliance with Microsoft and SpaceX, while OpenAI, Google and Anthropic stayed out of the room.
Nvidia joined Microsoft, SpaceX, IBM and more than 30 other companies in the Open Secure AI Alliance, a new effort to build and share open-source tools for AI security. The coalition said open tools are needed to defend against attacks from frontier models, pushing AI safety deeper into the infrastructure that protects software and systems.
The roster makes the launch politically sharp. Founding members include Nvidia, Microsoft, IBM, Dell, Red Hat, Hugging Face, Cisco and CrowdStrike, but not OpenAI, Google or Anthropic, three companies that have been central to earlier frontier-AI safety coordination. Those firms were among the founders of the Frontier Model Forum, which Google, Microsoft, OpenAI and Anthropic launched on July 26, 2023 to promote responsible development of frontier AI models.
CrowdStrike said it joined the new alliance to advance AI safety and security. Nvidia’s alliance blog post said open source software is a critical pillar of the global economy, and framed cybersecurity as one of the main reasons shared tools matter as frontier models and AI agents move into software and security operations.
The new alliance fits into a broader push that accelerated in 2024. On July 18, 2024, the Coalition for Secure AI was announced at the Aspen Security Forum in Boston as an OASIS Open project focused on secure-by-design AI systems. That effort, like the Nvidia-backed alliance, reflected a growing industry view that companies need common security frameworks, not just isolated proprietary defenses, as AI capabilities spread and threats become more automated.
The split is notable because the same companies that have led frontier-model safety talks are not all present in the new security coalition. With open-weight AI models and AI security controls now a policy issue in the United States, the launch gives Nvidia and Microsoft a visible role in defining the rules around AI security before regulators do. It also signals that the next fight over AI may be less about who can build the biggest model and more about who controls the tools used to defend against it.
