Good for Multisite WordPress Networks and how to installl correctly?

Hello there, I have been using Solid Security on standard WP sites before, now I want to secure a WP MultiSite network with more than 100 sites on subdomains.

Can Solid Security handle Multisites, and do I have to activate and configure it on each network site individually or can I protect the whole network by Network Activation and global configuration on the main network site?
