Anthropic is expanding verified AI model access to cybersecurity firms

Anthropic has expanded its Cyber Verification Program to include a third access tier, allowing more security organizations to access advanced AI models. The program provides qualifying security professionals with advanced cyber capabilities and reduced blocking classifiers.

The updated program offers access to Anthropic's most capable models, including Claude Opus 5.5, Claude Sonnet 5.5, and Claude Mythos 5.1. According to Techmeme, these models are also expected to include new models moving forward.

The company's generally available models have conservative cyber safeguards to limit harmful activities, but defenders need access to powerful tools to secure their systems. Anthropic has enabled trusted access through two previous programs: Project Glasswing and the Cyber Verification Program, which gave vetted security teams access to certain models.
