In a WordPress Multisite installation, you can log in to any account that exists on the network through any log in page on the network. As a result, if you have Jetpack Protect active on some sites but not all, then no site is truly being protected.
To address this, please network enable Jetpack on your multisite installation and activate the Protect feature on the network’s primary site. Once completed, Jetpack’s Protect feature will be activated on every site on your network, even if Jetpack isn’t connected on those sites.
