Is Defender as good as Wordpress Security?

Today I use Wordpress Security on mu site. Will Your plugin "Defender" be an option to choose in stead? I am wondering if I should change from WP Security to Defender. Will it keep me from being hacked and from brute force attacks and other stuff that WP Security helps with?

And the Cloud Backups with Snapshot plugin, is it a full backup plugin? If something happens to my site, I can just by a click get it up and running again? If my site get hacked, I will be secure and my site is safe?

You see that I am trying to understand if the plugins you provide is enough for my sites, or if I have to buy other plugins to be secure.

Do you have plugins that prevents comments spam and contact form spam?

I use Cloudways as my host.
