Network Access Overview for SimplySNAP Cloud

What is SimplySNAP Cloud?

SimplySNAP Cloud is a cloud based application that unifies control and reporting across multiple Synapse gateways.

What is a Synapse gateway?

A Synapse gateway is a specialized, hardened Linux appliance used to wirelessly monitor and control Synapse lighting controllers and sensor nodes. Each Synapse gateway comes standard with a 10/100 Ethernet port for management of the local web UI (HTTPS) via the customer LAN.

What communication is involved on my network?

All communications with the internet has to be initiated from the gateway, therefore no external connections can be established inbound. This prevents unauthorized access to the gateway from the outside.

Below is a description of each outbound connection to the cloud servers used by a Synapse gateway:
