What's more secure than an invisible network?
Not sure if you were aware that an "invisible" network is hardly secure, since there are any number of free utilities available over the Internet that will detect a "hidden" network in seconds, so anyone who really wants to see your network will be able to do so very quickly and very easily.
In addition, Apple specifically advises against using a "hidden" network in their best WiFi practices documentation, not only because of the ease in viewing a hidden network if desired, but also because it does make it difficult for some devices to even connect to the network.

It's your call, but I might briefly relate a quick story here. Recently, my neighbor mentioned to me that he had set up a "hidden" network to avoid having to enter a password for the network at all. His reasoning was that since he knew the name of the network and had stored it on his devices, that this was all that needed to protect and simplify his network.
After about 5 minutes, I called my neighbor and asked him to come over and see his network and devices on my computer. I'm a really lousy hacker, but he was shocked that I was able to get onto his network in about 60 seconds.
So, if you decide to "hide" your network, it would still be good idea to use a good strong WiFi password for the network. A strong password would be a mix of random letters and numbers. The longer the password, the more secure the network.....but....the longer it will take devices to connect.
