Robust Intelligence is an AI security company that builds an AI 'firewall' and automated red-teaming platform to detect, mitigate, and continuously test risks in machine learning and generative AI models. Founded in 2019 by Yaron Singer (a former Harvard CS professor) and Kojin Oshiba, the company provides tools that stress-test AI models for vulnerabilities, prevent unsafe outputs, and protect deployed models against adversarial attacks, data poisoning, and prompt injection. Robust Intelligence was acquired by Cisco in August 2024 to anchor Cisco's AI security strategy.
