1. PulseOne is advertised as needed only when you have several appliances, in order to manage them centrally. However, in order to use PulseWorkspace, PulseOne is required, even if there is only one appliance.
2. PulseOne in the cloud is free (comes with the Workspace license). If you want it on-prem you have to pay? :-\
Furthermore I am wondering what data is shared between PulseSecure Appliance and PulseOne (in the cloud). Honestly I do not feel terribly well with this.
Thank you for your interest in Pulse Secure products. 😊
1. Yes, that's correct. Pulse Workspace is not a separate appliance rather it's a runtime environment inside Pulse One.
2. Apparently, Yes. Pulse One + Pulse Workspace cloud offers 60 days trail license (Sadly, no trail in On-Prem) and subscription based license SKUs are available for both Pulse One and Workspace Cloud as well as On-Prem appliances.
Generally, Information like Pulse appliance configurations (XML), Logs, Health check statistics would be shared over SSL channel (REST API and DMI calls would be used).
