Moving from WebTitan OTG 1 to OTG 2 for Windows

Currently available for Chromebooks, Windows and Mac, the WebTitan OTG 2 family of agents sees the existing WebTitan OTG 1 agent being re-architected as a single-threaded application, giving more stability and security and requiring less CPU overhead from the user machine. However, this re-architecture means that there is no direct upgrade path from WebTitan OTG 1 to WebTitan OTG 2.

WebTitan OTG 1 is still supported and you can continue to use it, however, if you want to move your devices to WebTitan OTG 2 you will need to follow the guidelines below.

The WebTitan OTG 2 agent family offers other improvements:

  • You can remotely manage and configure OTG 2 devices after installation from WebTitan, using the device management UI.

  • You can view detailed device information on all your devices in WebTitan and apply global or individual configuration changes.

  • Reliance on a user's IP address has been removed, with OTG 2 using an EDNS tag to identify a user and their device.

  • You can automatically assign a specific policy to new devices during installation.

  • OTG 2 uses a customer-specific install key that improves security during installation. The install key can also be regenerated in the WebTitan UI if necessary.

Guidelines for moving from WebTitan OTG 1 for Windows to WebTitan OTG 2 for Windows

  • Ensure you read these topics:

  • For the purposes of these guidelines, it is important to understand that WebTitan OTG 1 for Windows creates a user and roaming location for each installation, while WebTItan OTG 2 for Windows creates a user, a virtual location, and a device.

  • Using the instructions in the WebTitan OTG for Windows Guide, carry out a number of test installations of WebTitan OTG 2 for Windows. Verify these test installations appear on your WebTitan Cloud and are filtering as expected.

  • When satisfied that the OTG 2 test installations are working as expected, delete your OTG 1 roaming locations from WebTitan Cloud. To do this, go to Environment > Locations.


    It is recommended to delete your OTG 1 roaming locations prior to installing OTG 2 to avoid any location confusion when OTG 2 virtual locations are added. However, if preferred, you can delete your OTG 1 roaming locations after OTG 2 installation.

  • It is recommended that you use the FULL_CLEAN parameter in your OTG 2 install script to fully remove any remaining OTG 1 files. More information is included in the installation instructions.

  • Carry out all your OTG 2 for Windows installations following the instructions in the WebTitan OTG for Windows Guide.
