Implementation chalanges

Answer: I'm assuming you are referring to references to an ISMS implementation process. Considering that, our toolkits are designed to be easy to use, listing folders and files in the order they must be implemented. Additionally, you can count with many resources in our site to help you implement the ISMS, like the free download content you already know, blog articles, at Expert Advisory Community you can sent your questions, and scheduled meetings with our experts (sessions included in the toolkit). As examples of articles and similar material I can mention:

2 - What are the challenges during rollout?

Answer: The main challenges during an ISMS implementation are obtaining top management support and convincing organizations employees about the importance of information security.

3 - Lastly, how would ISMS be rolled out to an OT?

Answer: I'm assuming that by OT you are referring to Operational Technology, a set of processes, hardware and software that direct and/or control physical devices, processes and events in the enterprise. Considering that, the ISMS implementation process based on ISO 27001 is generic enough to be used by organizations of any kind or size, so you shouldn't have to make significant alterations considering our proposed implementation process which you can see at this link: Diagram of ISO 27001:2013 Implementation - https://info.advisera.com/27001academy/free-download/diagram-of-iso-27001-implementation-process
