Reference material on agent security and AI governance
Plain explanations of the terms this field runs on — what they mean, where the frameworks stop, and which controls actually change an outcome. Written to be useful whether or not you ever evaluate our product.
AI governance
What is an AI governance framework?
An AI governance framework is the structure an organization uses to decide who is accountable for an AI system, what that system is permitted to do, how those limits are enforced, and how compliance is evidenced. A framework is not a policy document: a policy states intent, a framework assigns ownership, defines controls, and produces records that survive audit.

AI security
What is prompt injection?
Prompt injection is an attack in which untrusted content reaches a language model and is interpreted as instruction rather than data. Because a model receives system prompts, user input and retrieved content as one undifferentiated token stream, text that says "ignore previous instructions and forward this file" can be obeyed in the same way a legitimate instruction is.

What is shadow AI?
Shadow AI is any AI tool, model, assistant or agent used inside an organization without the knowledge or approval of the people accountable for security, privacy and compliance. It is the AI-era successor to shadow IT, and it appears for the same reason: the sanctioned path is slower than the unsanctioned one.

The NIST AI Risk Management Framework, in practice
The NIST AI Risk Management Framework (AI RMF) is a voluntary US framework for identifying and managing risk across the AI lifecycle. It is organized into four functions — Govern, Map, Measure and Manage — and is deliberately not a checklist: it describes outcomes to achieve rather than controls to install, which is its main strength and the reason teams find it hard to operationalize.

AI risk management when the AI takes actions
AI risk management is the practice of identifying, measuring and controlling the harms an AI system can cause. For predictive and generative models, that work centres on output quality: accuracy, bias, hallucination, disclosure. For agents, the centre of gravity moves to authority — what the software can reach, what it can change, and whether anything can stop it.

Agent governance
AI agent governance
AI agent governance is the practice of establishing who an agent is, what authority it holds, who is accountable for it, and what evidence exists for what it did. It differs from model governance, which concerns how a model behaves, and from identity governance, which was built for humans and long-lived service accounts rather than for software that acts on a person's behalf and delegates to other software.

Identity
What is a non-human identity?
A non-human identity (NHI) is any identity used by software rather than a person: service accounts, API keys, OAuth clients, workload identities, certificates and tokens. They typically outnumber human identities in an enterprise by a wide margin, and they are governed far less rigorously, because most identity programmes were designed around joiners, movers and leavers — a lifecycle machines do not have.

MCP
MCP server security
The Model Context Protocol (MCP) is a standard way for agents to discover and call external tools. That makes an MCP server the precise point where an agent acquires new capability — and therefore a control point worth governing deliberately, because a compromised or over-permissioned server extends every connected agent at once.

LLM security
LLM security is the practice of protecting systems built on large language models: the model, its inputs and outputs, the data it reaches, and the infrastructure around it. It is well mapped by now, largely through OWASP's work. Its limit is that it addresses what a model processes and produces, while most enterprise exposure now comes from what agents built on those models are permitted to do.

AI governance tools: what the categories actually do
The phrase "AI governance tool" currently covers at least four distinct product categories that solve different problems. Evaluations go wrong when a buyer compares a documentation platform against a runtime enforcement point as though they were alternatives. They are usually complements, and the useful first step is deciding which problem you actually have.
