CalypsoAI vs Robust Intelligence

CalypsoAI provides a full-lifecycle platform to secure AI models, applications, and agents at the inference layer against adversarial threats, data leaks, and compliance failures. The platform offers real-time threat defense, proactive red-teaming with agentic testing against thousands of attack prompts monthly, runtime guardrails for sensitive data and policy enforcement, and centralized observability with audit logs for regulatory needs. Targeted at enterprises deploying GenAI, it supports model-agnostic protection across SaaS, on-premises, and hybrid environments, enabling safe innovation without vendor lock-in. Acquired by F5 in 2025 for $180M, its capabilities integrate into F5's application delivery platform.F5 press release, Paladin press, homepage (279 words)

Robust Intelligence was a San Francisco-based AI security company co-founded in 2019 by Harvard computer science professor Yaron Singer and Kojin Oshiba. The company pioneered the concept of an 'AI Firewall' — a purpose-built platform that validates, stress-tests, and protects AI models from development through production. Key capabilities included algorithmic red teaming, automated model assessment, and proactive AI risk mitigation aligned to OWASP and MITRE ATLAS standards. Robust Intelligence was acquired by Cisco in October 2024 for a reported $400M and has been foundational to the development of Cisco AI Defense and Cisco Foundation AI. Its technology is now integrated into the Cisco Security Cloud, providing threat protection against prompt injection, data poisoning, jailbreaking, and unintentional model outcomes. The company raised $44M prior to acquisition across three rounds.
