# SixWays Firewall

> A reverse proxy for LLM traffic that scans prompts and responses in-flight, keeps provider keys server-side, and deploys in your own network.

## Every prompt and response, inspected in-flight.

The Firewall is a reverse proxy between your agents and their LLM providers. It scans traffic in both directions, resolves provider keys server-side so they never reach laptops, and runs inside your own network.

### Fast checks in line, deep checks behind them.

Cheap checks run on every request. The deeper layers run when an ambiguous verdict or a user's risk score calls for them, so an account that behaves unusually is scanned more closely.

#### Kinetic scanning

Signature checks catch known attack patterns, leaked secrets, and lookalike package names.

#### Semantic analysis

Prompts are compared with known attack corpora, which also catches attacks phrased differently from prior examples.

#### Cognitive classification

A safety model checks whether the exchange tries to manipulate the model, exfiltrate data, or subvert the agent. Responses keep streaming, token by token, during classification, and completed conversations can be re-audited in the background.

#### Adversarial confirmation

A larger guard model reviews the verdicts the classifier marks as ambiguous.

### Designed as network infrastructure.

#### Keys stay server-side

Agents authenticate to the gateway, which resolves the real provider key from [SixWays Secrets](https://sixways.ai/server/). You rotate a key in one place.

#### Your network, your data path

The Firewall deploys in your own network. Prompt and response content never transits SixWays infrastructure.

#### Gateway deployment

Point your tools at the gateway to cover every configured machine without installing a local agent.

#### Arsenal detection rules

Detection rules are compiled from the [SixWays Arsenal](https://sixways.ai/add-ons/#arsenal) test corpus, so the cases used to evaluate models are also used to protect them.
