Hi, I'm new to WordPress, and I've got a few questions about security.
1. Is there a way to block the public from seeing one of my sites, but keep it open for those who signed up for email updates? I run some marketing hubs (Some small businesses needed all their marketing in an easy to access location so I put it on a wordpress site) for some businesses, but would like to lock it down so that only they can see it. And so that if an employee is let go, they cannot access it again.
Is that possible?
2. What security plugins should I be running in general?
