At Operant our mission is simple: We’re in business to secure the modern world.



Operant AI is the only Runtime AI Application Defense Platform that actively protects every layer of live cloud and AI applications from infra to APIs. Operant's unique 3D approach brings discovery, detection, and defense into one platform, actively securing the entire "cloud within the cloud" including all APIs, services, and identities beyond the firewalls. Operant's platform blocks 80% of the most critical and common runtime attacks ranging from data exfiltration to AI supply chain attacks, model theft, prompt injection and many more. Within minutes of Operant's single-step helm deployment, security and platform teams gain a completely new level of real-time visibility and cloud-native defense for their entire cloud application stacks bringing frictionless security to dev, sec, and ops so that teams can deploy products and AI faster without security holding them back.
