Having your own WordPress instance gives you full control over user accounts and user metadata. You can onboard and offboard WordPress users to your site whenever you need to. Single Sign-On solutions are now available to sync your company’s existing user systems to your site.
There’s far less code loading on your instance that you can’t see. Most of VIP Go’s loaded code is publicly-available, so there’s no “black box” feeling and fewer surprises when you deploy.
