With ProcessRobot 2019 and onwards, we can create and provide access to custom users to our ProcessRobot installation. Those users could connect using a variety of different technologies. The following technologies have been tested with ProcessRobot 2019:
AWS VPC peering
No restrictions as long as the official guidelines are followed.
Any on-demand VPN solution between the ProcessRobot server and client components can provide sufficient connectivity. The key factor is that the connectivity should always be initiated by the ProcessRobot server.
Duo MFA version 18.104.22.1683 has been tested with ProcessRobot 2019 and verified that the connectivity is successful, including performing the "Autologin" functionality offered by the "Solobot" component.
