Enterprises are pausing development to fix vulnerabilities. A comparison of the approaches on the table.

In April 2026 Anthropic released Claude Mythos Preview to a closed group of companies and government agencies under Project Glasswing, a coalition that includes AWS, Apple, Cisco, CrowdStrike, Google, JPMorganChase, Microsoft, NVIDIA and Palo Alto Networks. The model finds software vulnerabilities on its own and at scale. By late May the partners had reported more than 10,000 high or critical vulnerabilities in widely used software, and a review of a sample of those findings by Anthropic and six independent security firms confirmed more than 90 percent of them as real. Anthropic has kept the model restricted and has described the ease of finding vulnerabilities, compared with the difficulty of fixing them, as the main challenge now facing cybersecurity.
