Important update for Off-Network Protection Clients (Windows and MacOS) from 2025-07-08 00:00 EDT to 2025-07-08 00:01 EDT

There is an urgent software upgrade required for all CIRA DNS Firewall Off-Network clients for Windows and macOS. This upgrade is necessary due to an unexpected issue with our downstream service provider.

To avoid service disruption, please upgrade your client immediately:

• New device registrations are no longer possible
• Previously registered devices will stop functioning between now and July 25

If you have already completed the upgrade, no further action is required. Otherwise, please follow the upgrade instructions as soon as possible.

Windows, manual installation:

Warning: if you are currently running a version earlier than 2.18 such as 2.10, 2.12, or 2.16, you will need to first perform the instructions at https://status.cira.ca/incidents/242994 to uninstall the old clients and then you may proceed with the instructions below to upgrade to 2.20

1. Generate a new activation link for any device group
2. Open the link in a browser to download a .msi file of the new version
3. Double click on the .msi file to install the latest CIRA DNS Firewall application version

Note: you do not need to generate multiple activation links or reactivate your devices

Windows, MDM installation:

Warning: if you are currently running a version earlier than 2.18 such as 2.10, 2.12, or 2.16, you will need to first perform the instructions at https://status.cira.ca/incidents/242994 to uninstall the old clients and then you may proceed with the instructions below to upgrade to 2.20

MacOS, both manual and MDM installation:

1. The MacOS application comes from the Apple Store
2. Generally, Apple store applications are upgraded automatically when there is an upgrade
