As part of our case study we are looking for an alternative tool for Sitecore,

1. We have used Sitecore Experience editor to customize/configure the pages and viewing the response preview there itself. Whether this feature is available in Umbraco?
2. Currently we have 250-300 multisites which runs under a tree, does umbraco supports these many sites under the single instance?
3. We have a parent site in which multi-tenants are running under the single instance. Does umbraco support multitenants with single instance?
4. We are creating sites programmatically using custom wizards, will thise be achievable in umbraco?
5. Sitecore has a branch template feature where we have customized page templates and renderings configured in a tree structure. We use wizards to create the new site from the branch template everytime. Whether umbraco supports this feature?
6. We used to have customized workflows to perform some commands/actions. Whether Umbraco supports this?
7. How SSO feature is achievable in umbraco?
8. User Management/ Is it possible to create custom properties to store additional user information (ex: firstname, lastname)
9. Will Umbraco handles custom roles and role permissions?
10. Restricting the user to perform actions specific to the role and based on the custom domain? (ex: Only roles with admin can able to make changes in the specific module)
11. Different types of rendering a template is available in Sitecore like Item rendering, controller rendering, view rendering. Is there any specific concepts available in Umbraco to render multiple views?
12. We have multi-tenants and sites running under single instance of sitecore. When we are programmatically creating a site, will the entire Umbraco instance restart?
13. What kind of encryption we have in Umbraco, especially PII data?

Note: Please share any case studies with the above scenarios
