Validators need a Sentry? What's the required architectural setup?

Hi,

I am new to Cosmos network.
I read the docs and I would like to setup a validator.
However I would like to know if for a Cosmos Validator we need to employ a setup which requires a Sentry computer.
I have seen other cryptocurrencies setup require a sentry computer in order that the node producer is never connected to the internet.
I could not find any reference in the Cosmos docs that a Sentry is required.

I would appreciate if someone has some time to clarify this for me.
Please receive my thanks in advance.

All the best,
Alex

It is not required but recommended.
The purpose is to have redundancy, and also a layer of protection.
