Let AI work. Keep data home.

A policy gateway between your people, agents, and every model — prompts, copilots, and MCP tool calls checked before anything sensitive leaves.

Every AI surface is an exit.

Six surfaces, one gateway — the same policy answers whether a human typed it or an agent called it.

Prompts

Prompts & chats

ChatGPT, Claude, Gemini — typed and pasted content checked before send.

Copilots

Copilots & assistants

M365 Copilot, coding assistants — context windows scoped to what each user may see.

MCP

MCP tool calls

Every tool call policy-checked in-line — allow, redact, or block per field.

Agents

Agent workflows

Multi-step agent chains traced end to end — every hop carries identity and policy.

Pipelines

RAG & training data

Embedding and fine-tuning pipelines screened so restricted data never enters a model.

Shadow

Shadow AI apps

Unsanctioned tools and browser extensions discovered from real traffic — then governed, not just banned.

Capabilities

Say yes to AI, safely.

Four things the gateway does that a blocklist never will.

Field-level redaction

Redact the field, not the workflow.

Blocking a whole tool call breaks the agent. The gateway strips only the sensitive fields and forwards a clean payload — work continues, data stays home.

Shadow AI census

Know every AI your company uses.

The census comes from real traffic — every model, extension, and wrapper app, with users, data flows, and a sanction decision. New tools surface in days, not audit cycles.

In-prompt coaching

Teach in the moment, not in training.

When a prompt carries sensitive data, the user sees why — and gets a one-click safe version. Behavior changes where it happens, and repeat rates fall within weeks.

This prompt contains PII headed to a personal AI account. Argus can strip identifiers and keep the task intact.

Agent audit trail

When the agent acts, you can prove what happened.

Every tool call in an agent chain is logged with identity, payload classification, and the policy decision — a replayable trail for incident response and auditors alike.

One policy — human exits and AI exits alike.

The gateway shares its policy language with DLP — write the rule once, and it holds at USB, browser, email, and every model.
