Last night, companies using Anthropic’s Claude Fable 5 and Mythos 5 models discovered they were simply gone. A U.S. government export directive forced them offline for every person and company outside the United States (including Anthropic's own employees), effective immediately.

Europe needs to react fast, allocating a percentage of defense and resilience budgeting to EU sovereign solutions and vendors to hedge against an increasingly uncertain geopolitical landscape.

AI has become a trusted “colleague” for many SMBs. But like any colleague, it needs clear rules and oversight. The ESET SMB Cyber Readiness Index 2026 shows a complicated reality: SMBs are embracing AI, but many are still catching up on the risks. (1/2)
