Runtime Defense for Cloud, APIs and AI Applications

Operant AI provides a Runtime AI Application Defense Platform engineered to secure every layer of live cloud and AI-driven applications, from infrastructure and APIs to model interfaces. The company frames its mission around a 3D security approach that unifies discovery, detection, and defense capabilities into a single platform designed for modern, dynamic environments.

Operant’s platform protects the full cloud-within-the-cloud environment, covering APIs, services, data flows, and identity layers that sit beyond the reach of traditional firewalls. Its

runtime protection system blocks critical threats including data exfiltration, LLM prompt injection, AI supply chain compromise, model theft, and poisoning attempts. With real-time visibility across cloud-native stacks and simple helm-based deployment, Operant enables enterprises to integrate continuous AI security without disrupting operations.

In September 2024, Operant AI raised a $10 million Series A co-led by SineWave Ventures and Felicis with participation from Alumni Ventures, Massive, Calm Ventures, and Gaingels, as well as unnamed angels. After the Series A, total funding stood at $13.5 million.
