NVIDIA's AI security shows up here as two free open-source tools, with no commercial terms disclosed in the cited record: garak, which attacks a language model to find its weaknesses, and NeMo Guardrails, which sits in front of a model at runtime to block unsafe input and output. Both ship free and open source on their project pages, no direct revenue from either appears in the cited record, and their documented tie is into NVIDIA's broader NeMo tooling, so they read as ecosystem positioning rather than a business of their own. The two cover opposite sides of the same problem, offense and defense, which is the shape of this portfolio. This page covers those two tools. NVIDIA's wider security work, including Morpheus, is not analyzed here.
| Description | NVIDIA ships open-source AI security tools, including garak, a generative-AI red-teaming and assessment kit that probes language models for prompt injection, jailbreaks, data leakage, toxicity, and misinformation. | [f1] |
|---|---|---|
| Deployment | Self-hosted | [f2] |
| Product | What it does |
|---|---|
| garak | garak: Open-source LLM vulnerability scanner from NVIDIA that probes models for prompt injection, jailbreaks, data leakage, toxicity, and misinformation using static, dynamic, and adaptive probes. |
| NeMo Guardrails | NeMo Guardrails: Open-source NVIDIA toolkit that adds programmable input, dialog, retrieval, execution, and output rails to LLM applications, with built-in jailbreak and content safety checks. |
| OpenShell | Open-source sandbox runtime for autonomous AI agents that isolates each sandbox in its own container, starting from minimal outbound access that a short YAML policy widens per HTTP method and path. |

| AI Orchestration Tools Agentic orchestration tools, plus their plugins, skills, hooks, system prompts, scaffolding, harnesses, configuration settings, and MCP clients on user devices. | ||||||
| AI-Generated Code Code produced by AI tools, AI-assisted reviews, AI-generated infrastructure-as-code and tests, and vibe-coded apps that bypass CI/CD. | ||||||
| AI Gateways & Routers MCP proxies and gateways, LLM routers, outbound AI-service traffic, shadow AI egress, and model-registry traffic. | ||||||
| AI Model Model weights, fine-tuning checkpoints, model cards, registries, AIBOM, and the third-party LLMs your enterprise consumes. | ||||||
| Training Data Datasets used for training, fine-tuning, and continued learning. | ||||||

NeMo Guardrails adds programmable input, dialog, retrieval, execution, and output rails to LLM applications with built-in jailbreak and content safety checks, and garak probes models for prompt injection, jailbreaks, and data leakage. These lines are mapped to the AI Defense Matrix. [f3]
Each line is scored on its own and compares head-to-head with rivals in its category. The page groups the lines rather than averaging them, because the spread across them is the point.
| Security line | Market readiness | Defensibility |

These are the security lines we've analyzed so far, not a complete map of this company's security portfolio. Not yet analyzed: NVIDIA Morpheus, NVIDIA Confidential Computing.
NVIDIA's play in AI security here is to lead the open-source tooling, and the cited record discloses no direct revenue or commercial terms for either line. garak and NeMo Guardrails are both free per their project pages, no license revenue from either appears in the cited record, and NVIDIA's visible return reads as positioning and ecosystem standing. That makes this portfolio read differently from a vendor selling a paid platform.
The two lines sit on opposite sides of the model. garak is offense: it runs adversarial probes to find where a model breaks, the way a scanner audits a network. NeMo Guardrails is defense: it adds programmable rails that block unsafe input and output at runtime. The two reinforce each other, because a team can point garak at a guardrailed endpoint to measure how well rails like NeMo's actually hold.
Both rate modestly on market readiness because the cited record shows no commercial terms or revenue for either. garak shows no revenue and no named customer in the record, while NeMo Guardrails pairs with NVIDIA's NIM safety microservices, for which the cited record carries no pricing, and press coverage names Amdocs as an adopter. It scores slightly ahead on that named-adoption evidence. Both are free and portable per their project pages, so what durability appears comes from NVIDIA's stewardship of the projects rather than from switching cost.
The honest read is that this is a credibility and ecosystem play, with no security business of its own visible in the cited record. The page scores the two tools as the open-source lines they are, and NVIDIA's broader security work is not covered here.
