# LLM security tools

The stack that protects LLM applications: input/output filters, firewalls and gateways, runtime enforcement, red teaming, and observability. No single tool covers all five.

[

### MCP (Model Context Protocol)

An open protocol that connects agents to external tools and data. Powerful for capability. But every connection is a new access path that has to be governed.

### MCP Gateway

A governed checkpoint every tool connection passes through (authenticated, policy-checked, and logged) so credentials stay central and unapproved servers can't connect.

### Mission drift

When a non-deterministic agent gradually diverges from its intended task. Tracked at runtime so it can be contained before consequences land.

### Non-human identity (NHI)

Identities belonging to machines, services, and agents rather than people. Agents are the fastest-growing and least-governed class of NHI.

### On-behalf-of (OBO) chain

The unbroken provenance recorded on a credential (who authorized the action, what scope was granted, and how deep the delegation goes) so an audit walks back to a human.

### Prompt injection

An attack that manipulates an agent through crafted input (in a prompt, a tool result, or retrieved content) to make it act against policy.
