'Yellow Teams' Are Defining the Future of AI Security

A growing trend of ‘yellow teams’ – engineering groups building both attack and defense tools – is emerging as a crucial response to the increasing threat of AI-powered cyberattacks. These teams are using advanced AI models like Mythos (Anthropic) and GPT-5.5 (OpenAI) to proactively identify vulnerabilities and develop defenses. Organizations are increasingly collaborating between ‘red’ and ‘blue’ teams, with yellow teams providing the technical expertise to effectively wield these AI models. This collaborative approach is vital for organizations to stay ahead of the rapidly evolving AI threat landscape and integrate AI security into their software development lifecycle.
