Side-by-side comparison of AI visibility scores, market position, and capabilities

About
Noma Security was founded to address the emerging and largely unaddressed security surface created by enterprise AI adoption. As organizations deploy AI systems, ML pipelines, and autonomous agents into production, they introduce new attack vectors — data poisoning, model theft, prompt injection, and unmonitored agent behavior — that conventional security tools are not designed to detect or prevent. Noma was built from the ground up to secure AI development pipelines and deployed AI agents in enterprise environments, with a platform that spans the full AI lifecycle from development through production.\n\nNoma's platform provides visibility and protection across AI supply chains, covering model provenance, training data integrity, API security, and real-time monitoring of AI agent behavior. It integrates with enterprise development environments and cloud platforms to surface risks that would otherwise go undetected by security operations teams unfamiliar with AI-specific threat models. Noma serves enterprises across regulated industries including financial services, healthcare, and technology, where the consequences of AI system compromise carry significant compliance and reputational risk.\n\nNoma raised a $100 million Series B in July 2025, bringing total funding to $132 million raised in under two years — an unusually fast fundraising trajectory that reflects both category urgency and strong early commercial traction. The company has grown ARR by 1,300% and is recognized as the fastest-growing company in the AI security category. As AI agents proliferate across enterprise environments, Noma's first-mover position in purpose-built AI security positions it to become essential infrastructure for any organization deploying AI at scale.
