Noma Security

Primary category: ai-spm. Also spans agent-runtime-security.

One-liner — An end-to-end AI and agent security platform that discovers your AI/agent estate, scores its posture, red-teams it, and protects it at runtime.

What it does

Noma sits across the AI lifecycle. It continuously discovers AI assets — models, datasets, notebooks, pipelines, and increasingly AI agents — across cloud accounts, code repos, and ML/AI development platforms; builds an inventory and posture view (AI-SPM); runs AI red teaming to find prompt-injection and jailbreak weaknesses before deployment; and provides runtime protection for live AI agents and applications (guardrails on inputs/outputs and agent actions). The pitch is one platform instead of stitching a posture tool, a red-team tool, and a runtime firewall together.

Where it sits in the stack

Primarily ai-spm (inventory + posture + governance of AI assets), extending into agent-runtime-security for live agent protection. Layer: model/prompt. It inspects untrusted input (prompt-injection detection), watches sensitive data moving through AI/agent flows, and can constrain outbound data flows and tool actions. Lives mostly in the yellow/green zones around enterprise AI workloads.

Deployment & architecture

SaaS control plane with API/agent-based connectors into cloud (AWS/Azure/GCP), code repositories, and AI dev platforms (e.g. Databricks — note Databricks Ventures is an investor). Runtime protection inserts guardrails into the application/agent path. Integrates with the AI development toolchain it discovers; SIEM/SOC export is the usual pattern for posture/runtime findings.

Positioning & differentiators

Known for being one of the louder “end-to-end agentic AI security” plays — combining discovery + posture + red teaming + runtime in a single platform, where many neighbors do only one slice. Closest neighbor is zenity, which similarly spans AI-SPM and agent runtime but came up through copilot/low-code security; Noma came up through the ML/AI data-and-pipeline posture angle. Other adjacents: reco and nudge-security (lighter AI-SPM/shadow-AI), prisma-airs and straiker (runtime-leaning), and AI red-teaming specialists like hiddenlayer.

Ownership, funding & M&A

Independent, VC-backed. Founded 2023 by Niv Braun (CEO) and Alon Tron; emerged from stealth November 2024. Series A (Oct 2024) led by Ballistic Ventures; $100M Series B (July 2025) led by Evolution Equity Partners with Ballistic, Glilot Capital, Cyber Club London, Databricks Ventures, and SVCI — bringing total funding to roughly $132M. No M&A; no seed acquisition flag. Ownership confidence: high (independent). (One PR render listed “founded 2024”; multiple profiles + the stealth timeline support 2023 — medium confidence on the exact year.)

CTO / hedge-fund lens

Day-2. This is a consolidation buy once you already have AI/agents in production and want a single pane for “what AI do we have, how exposed is it, and is anything being attacked right now.” Noma explicitly courts financial-services buyers, so the regulated-shop framing (SR 11-7 model inventory, evidence for model-risk review) is part of the story — though Noma is a security posture tool, not a model-risk/governance platform like credo-ai. For a hedge fund: relevant if you’re building/hosting your own agents at scale; overkill if your AI footprint is a couple of SaaS assistants behind an ai-gateway.
