Anthropic Widens Access to AI Security Tool, Commits $35M to Open Source Defenders

Anthropic has announced it is broadening access to Mythos 5, its AI model designed to help defenders identify security issues, as part of an expanded rollout of Claude Security. The tool, currently in public beta for Claude Enterprise customers, can scan codebases to help organisations spot vulnerabilities before attackers do.

Alongside this expansion, Anthropic revealed a $35 million fund aimed at supporting open source security initiatives. While details on how the fund will be distributed remain limited, the move signals growing investment from AI companies into strengthening the broader security ecosystem that many businesses, including small and medium enterprises, rely on indirectly through open source software.

For Australian small businesses, developments like these matter even if they don't use Claude directly. Much of the software underpinning everyday business tools depends on open source components, and investment in securing that ecosystem can have flow-on benefits for everyone.
