Robust Intelligence

Robust Intelligence pioneered the concept of an 'AI Firewall,' a purpose-built platform that validates, stress-tests, and protects AI models from development through production, and is now part of Cisco. Its two core capabilities are algorithmic red teaming, which automatically probes models for vulnerabilities and failure modes, and a runtime AI Firewall that inspects inputs and outputs to block prompt injection, jailbreaks, data leakage, personally identifiable information exposure, and unsafe or off-policy responses. The platform maps risks to industry frameworks such as OWASP for LLMs and MITRE ATLAS, and provides continuous, automated assessment so teams can validate models before deployment and monitor them in production. Co-founded in 2019/2021 by Harvard professor Yaron Singer and Kojin Oshiba, the company raised roughly $44M and was valued above $200M before Cisco acquired it in 2024 for a reported ~$400M. Its technology became foundational to Cisco AI Defense and Cisco Foundation AI, integrated into the Cisco Security Cloud to defend against prompt injection, data poisoning, jailbreaking, and unintended model behavior. Robust Intelligence is aimed at security and ML risk teams at larger enterprises that want both proactive adversarial testing and inline runtime protection standardized against recognized AI-security taxonomies.
