# Prerequisites

To make the most of securing your Internet traffic and SaaS apps, make sure that you have the following:

* A device that can run [Cloudflare One Client](https://developers.cloudflare.com/cloudflare-one/team-and-resources/devices/cloudflare-one-client/download/), Cloudflare's endpoint agent.
* (Optional) A [Linux host server](https://developers.cloudflare.com/cloudflare-one/team-and-resources/devices/cloudflare-one-client/download/#linux) on the private network that can run Cloudflare Mesh, a software agent similar to the Cloudflare One Client.
