Just the CRM
Is your organization hosting CiviCRM separately from your main site?
I've seen a few organizations do this, and it's a good idea in certain situations.
For a long time, the only way to do it was to spin up a separate Drupal or WordPress site that really did nothing else but contain CiviCRM.
But these days, it's worth considering CiviCRM Standalone.
It's just CiviCRM, so you don't have the burden of security updates and bug fixes for Drupal or WordPress.
But you do get all the necessary features for multiple user roles and permissions, switching users, and more.
If your separate CiviCRM site really is just CiviCRM, you might consider switching to Standalone.
It can be a whole lot simpler to manage.
All the best,
A.
P.S. If you're having trouble imagining what “just CiviCRM” would look like, head over to the official CiviCRM Standalone live demo site, where you can log in and give it a spin.
