Configuring Cloud Safe Network

This article is intended for IT Support at schools which use School Manager to manage students’ access to their network and internet connections.

Cloud Safe Network allows you to use Linewize technologies in a cloud-only environment without needing a physical School Manager appliance. Schools using Qustodio’s Safe Network feature must enable Cloud Safe Network.

What is the Cloud Safe Network?

Cloud Safe Network is an important component of the Linewize Cloud service. The Connect agent sends network safety checks to the service to determine if the network a device is connected to is safe or unsafe. Cloud Safe Network compares the source IP address of incoming requests with a list of school IP address associations. All networks are considered unsafe by default.

If the IP address matches a known association, Cloud Safe Network reports the network is safe and tells the Connect or Qustodio agent to stop filtering. This is important if school users connect to a school network already being filtered or if you are using an alternate filtering solution.

If the IP address does not match a known association, Cloud Safe Network reports the network as unsafe and the Connect or Qustodio agent continues to filter. This is important to ensure school users connecting to non-school networks are protected by School Manager or Qustodio filtering policy.

IP Address Outcome
Matches known association Safe network. The Connect agent stops filtering.
Does not match any known association Unsafe network. The Connect agent continues filtering.
