AI Security covers the tools that protect machine learning systems, large language models, and AI applications across their full lifecycle, from training data and model weights to the agents and prompts running in production. It is what you reach for once your organization ships AI features and has to answer the questions a board and a regulator will ask: who can reach the model, what can it be tricked into doing, and where did its data come from. The space breaks into distinct problems. Agentic AI Security and LLM Guardrails handle runtime behavior, prompt injection, and output filtering. AI Red Teaming and AI Data Poisoning Protection stress-test and defend the model itself. AI SPM, AI Model Security, and MLSecOps deliver inventory, posture, and pipeline controls. AI Governance ties all of it to policy and compliance. Most CISOs assemble coverage from several of these rather than one platform, because no single tool credibly does all eight.

Common questions about AI Security tools, selection guides, pricing, and comparisons.
AI Security is the practice and tooling for protecting AI systems, including machine learning models, large language models, and the agents and applications built on them. It spans training data, model weights, inference endpoints, and runtime behavior. The goal is to stop attacks like prompt injection, data poisoning, and model theft while keeping AI deployments inventoried, governed, and auditable.
Traditional AppSec assumes deterministic code you can scan and patch. AI systems are probabilistic, so the attack surface includes the model's behavior itself: prompt injection, jailbreaks, data poisoning, and model extraction have no equivalent in a normal web app. AI Security layers model-aware controls like guardrails, red teaming, and posture management on top of the AppSec and cloud security you already run, rather than replacing them.
Begin where your exposure is. If you have shipped customer-facing AI features, LLM Guardrails and Agentic AI Security address the most immediate runtime risk. If you cannot list what models and AI services are running, AI SPM gives you inventory and posture first. AI Governance matters early when the EU AI Act or similar regulation applies. Most teams end up needing several of these, not one.
Your existing stack covers the infrastructure around AI but not the model behavior. Cloud security, DLP, and IAM still apply to the servers and data stores. None of them detect a jailbroken prompt, a poisoned training set, or an agent calling tools it should not. Dedicated tooling fills that model-specific gap, which is why categories like AI Red Teaming and MLSecOps exist on their own rather than as features bolted onto general security platforms.
Yes. Open-source projects exist for red teaming, prompt-injection testing, and model scanning, and they are a reasonable way to size up the threat and prove value before buying. The trade-off is that open-source tooling rarely includes managed threat intelligence, production-grade runtime guardrails, or the governance reporting compliance teams want. This category spans both open-source and commercial options, so you can match the choice to your maturity and budget.
