01

### AI Gateway and MCP Firewall

A provider-compatible gateway that inspects model traffic and tool execution before risk reaches production systems.

**Inspect**Detect prompt injection, secrets, PII, jailbreaks, and unsafe output inline.

**Route**Send traffic through governed providers with failover, budgets, and semantic caching.

**Prove**Keep the trace, policy verdict, latency, cost, and evidence for every model request.

### Private AI Portal

A governed, branded workspace that gives employees useful AI without unmanaged accounts or invisible data exposure.

**Give teams one approved workspace**Deploy a branded AI portal with governed assistants and knowledge.

**Keep data inside policy**Apply the same gateway controls to every employee conversation.

**See adoption and risk**Understand usage, sensitive-data events, cost, and policy outcomes.

Inline

### Stop risk before execution

Block, mask, warn, or log at the gateway and MCP boundary.

Efficient

### Control cost and latency

Route intelligently, cache safely, and see spend by model and team.

Auditable

### Retain the decision trail

Every trace carries the inputs, policy verdicts, and security evidence.

Portable

### Deploy on your terms

Use open source locally, self-host, or connect to the managed EU cloud.

Developer first

## One endpoint change. Immediate control.

Keep your existing provider SDK. Point it at Bastio, add an API key, and every request gains policy enforcement and observability.

[Quickstart](/docs/getting-started) [API reference](/docs/developer-apis)

OpenAI-compatible Scoped API keys Request-level traces

quickstart.tsCopy

```
import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.BASTIO_API_KEY,
  baseURL: "https://gateway.bastio.com/v1"
});

const response = await client.chat.completions.create({
  model: "gpt-4.1",
  messages: [{ role: "user", content: prompt }]
});
```

Ready for production

## Make every AI interaction accountable.
