Hi @olauret,
We use one or more of the following protocols when we communicate with the FPolicy server: http(s), tcp, or CIFS(NFSv4 possible in the future).
You can reference the following KBs for some additional information on NetApp FPolicy
KB: FPolicy: What is it and what does it do
KB: What are the FPolicy partner solutions for ONTAP?
The 2nd KB includes some additional links to our Technical Reports for specific vendors. We also provides a cloud based fpolicy solution Cloud Secure via Cloud Insights.
Let us know if you have any additional questions.
Thanks,
Brad
Team NetApp
