# RADIUSaaS Documentation

Certificate-Based Authentication for Wi‑Fi, VPN, and Wired Networks

RADIUSaaS offers easy and secure authentication for accessing network resources. It delivers the comfort, reliability, and scalability of a native cloud SaaS. Supported protocols are RADIUS as well as RadSec. Authentication is based on certificates. RADIUSaaS is generally capable of validating every certificate that can be used for client authentication. However, to be able to lock someone with a revoked certificate out of your network, choose a CA which provides a publicly accessible OCSP or CRL endpoint.

These docs cover technical aspects of RADIUSaaS. All other information can be found on the [RADIUSaaS website](https://radius-as-a-service.com/).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.radiusaas.com/readme.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `build a script that syncs our docs to a CMS` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
