In a nutshell: Yellow Teams combine attack and defense perspectives to systematically identify AI security risks before models are deployed in production.
Organizations are increasingly deploying so-called Yellow Teams to test AI systems for security risks. These teams develop both defensive and offensive tools to evaluate opportunities and threats posed by AI to cybersecurity.
Yellow Teams are specialized units that systematically test AI systems for vulnerabilities. Unlike traditional Red Teams (attackers) and Blue Teams (defenders), Yellow Teams combine both perspectives: they develop attack and defense tools in parallel to gain comprehensive understanding of the security landscape.
For CISOs, this practice is relevant because AI models are increasingly deployed in security infrastructures — from anomaly detection to automated threat response. Without structured security testing, blind spots emerge: models can be manipulated, poisoned, or circumvented. Yellow Teams help identify these risks before production deployment.
The methodology enables organizations to defensively assess AI-based security solutions while simultaneously modeling new attack scenarios. This is essential both to build confidence in proprietary AI systems and to proactively respond to new threat models that could be created by AI itself.
