Fiddler AI vs Robust Intelligence

Fiddler AI provides an observability and security platform that monitors, analyzes, explains, and governs predictive ML models, generative AI, and agentic applications across their lifecycle. The platform offers visibility into agent behaviors, root cause analysis for failures, real-time guardrails for safety, faithfulness, PII detection, and policy enforcement. It supports enterprises in building trust through continuous monitoring, auditable logs, and evidence collection for compliance needs like GDPR and HIPAA. Targeted at Fortune 500 companies, particularly in financial services for use cases like fraud detection, risk assessment, and chatbots, Fiddler distinguishes itself with agentic observability, Fiddler Trust Models for cost-effective evaluations, and native integrations with tools like LangGraph and AWS SageMaker.

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.
