Operant AI is the industry-defining cybersecurity leader at the forefront of securing AI and Agents. Operant's 3D AI Defense Platform defends every AI and agent surface in real time, from cloud to endpoints. Through Discovery, Detection, and Defense, Operant delivers comprehensive, real-time active defense across the full agentic stack — Agents, AI applications, LLMs, APIs, MCPs, skills, and cloud — with runtime and intent-based enforcement before autonomous actions happen rather than after-the-fact alerts. Operant's core products include AI Gatekeeper, MCP Gateway, Agent Protector, Endpoint Protector, and the Operant Semantic Firewall, which understands the intent behind every agent action and enforces an allow, block, or redact decision inline, in real time. Together, they give security and AI engineering teams a single platform to stop harm before it happens — whether caused by an attacker or emergent agent behaviors — and to deploy AI at scale without sacrificing control. Operant is proud to support sovereign AI and air-gapped environments, extending real-time defense to the most sensitive and regulated deployments. Founded by industry veterans from Apple, VMware, and Google, Operant AI is the only vendor featured across six of Gartner's critical AI security reports — spanning AI TRiSM, API Protection, MCP Gateways, Securing the Risks of MCP, How to Secure Custom-Built AI Agents, and LLM Supply Chain Security — and has been recognized by CRN as one of the hottest Cyber startups and hottest AI startups of 2026.
