# OneDevice Parallel

## Intro

OneDevice Parallel, a product by OneFirewall, works alongside your existing firewall — whether it’s pfSense, FortiGate, Check Point, or Sophos. It monitors network activity and prevents cyberattacks in real time by analyzing logs and automatically updating security rules.

## Use Cases

Small and medium-sized organizations often already have a firewall in place but aren’t fully leveraging its capabilities. OneDevice helps them operationalize and maximize the protection their firewall can provide.

## OneDevice Overview

**OneDevice** is a compact physical appliance provided by **OneFirewall Alliance Ltd.** (or its alliance partners). It is installed directly within the customer’s network to enhance real-time monitoring and protection.

### Software

Each OneDevice comes pre-installed with a proprietary OneFirewall application designed and maintained by OneFirewall Alliance.

### Network Operation

Once powered on and connected, the device listens on the following ports:

* **UDP 514** — Receives network metadata logs (syslog format) from your existing firewall
* **HTTPS 443** — Hosts the rule engine, providing updated rules for integration with your current firewall

### Cloud Connectivity

The device maintains a secure, continuous connection with the **OneFirewall Control Framework (WCF)** — a centralized management console used to monitor performance, push updates, and manage device operations.
