# OneDevice Parallel

## Overview

OneDevice Parallel is a OneFirewall appliance that runs alongside your existing firewall — pfSense, FortiGate, Check Point, Sophos, or others. It analyzes logs from that firewall and updates security rules in real time.

## Use Cases

For organizations that already have a firewall in place but aren't fully using its capabilities. OneDevice adds the monitoring and rule automation needed to operationalize that firewall's protection.

## Compatibility

**OneDevice** is a compact physical appliance provided by OneFirewall Alliance Ltd. (or its alliance partners), installed directly within the customer's network.

## Notes

* Network operation: once powered on and connected, the device listens on UDP 514 (receives syslog metadata from your existing firewall) and HTTPS 443 (hosts the rule engine that feeds updated rules to your existing firewall).
* Cloud connectivity: the device maintains a continuous connection to the OneFirewall Control Framework (WCF), the console used to monitor performance, push updates, and manage device operations.
