These are 3 different topics.
Weekly Content
There is weekly content that is downloaded into your instance via a scheduled job. This will bring down the latest Publishers, Products, Normalization Rules, etc.
To get the latest content, you don't need to "Opt-In", you just need the scheduled jobs running. No data leaves your instance, so I would expect that your Security team would be ok with that.
There is a dashboard available to see what version of the content you are on and to check to see if all of the data has been downloaded.
Content Service Opt-In
The Opt-In Content Service is useful to help identify the items in your environment that haven't already been addressed and sends them to our content team so they can do the research and add it to the central library.
There is an Opt-In to the content service for your instance to send Unmatched Content, Unmatched Publisher Part Numbers, etc. You can toggle what data you want to send.
In order to "automatically" send data from your instance to the Content team, then you would need to Opt-In to the service. If your Security team has an issue with that, you can always open a HI ticket and provide the details on the Publishers, Products, Normalizations rules that you want the content team to create.
Support for On-Premises Content Download
The Import that you referred to is for Customers that are On-Premises. For customers that aren't able to connect to the Central Library, there is an option to connect to an FTP site and download the Content library and then manually update their On-Premises Instance.
On-premises customers must submit a request in HI for access to the FTP folder for on-premises content library support. A unique user name and password, along with the FTP folder address will be provided.
On-premises customers must activate the “Manage Software Library” module. To do so, navigate to System Definition -> Modules. Search for module title “Manage Software Library”. Set Active equals to “True”. This will activate the module necessary to easily upload content library files and download non-normalized information.
Once the “Manage Software Library” module is enabled, on-premises customers can navigate to Software Asset -> Administration -> Manage Software Library.
The content itself is updated weekly. You can change the schedule to whenever you want. You can also execute the individual jobs one by one. They are listed under System Definition..Scheduled Jobs.
I usually filter on *Download S to get the Software Content jobs.
You open each record and you can click Execute Now
