Mac security is full of misinformation and meh products, especially on the consumer end of things. Gatekeeper helps, but is only one layer of defense (that has gaps). Xprotect is another layer, but also has gaps (and is slow). Consumer-grade software falls into two categories - stuff like Little Snitch that does one thing well, but isn't a complete solution, and legacy all-in-one stuff that, well, isn't exactly the best. You really want to protect a mac? Buy a commercial grade solution like Crowdstrike.
This is a major issue with Apple though - without a published support plan, everyone is at the mercy of their goodwill. We get hardware lifespans...really need software ones too.
