I think Island can be improved in terms of change management and adaptation. The user has to switch browsers, getting Island set as a default, and stopping people from going back to Chrome or Edge for corporate apps takes policy enforcement and communication. The browser extension options help cover what happens beyond the browser. Island only protects what happens in the browser. Native desktop apps, thin clients, Outlook desktop, SAP, and local Office files need other tools. Therefore, it does not fully replace VDI or endpoint DLP in every scenario. However, there is a newest advantage for mobile parity because mobile platforms do not get offered the full set of desktop controls. I would add that mobile is the weakest area today. The controls we enforce on desktop are not fully available on iOS and Android. For mobile users, we still depend on our MDM solution. My advice is to start with one clear use case such as contractor access and expand from there. The technical deployment is the easy part, but policy design and user communication take real effort.
