How to prevent access for a site collection in SharePoint Server?

To prevent users to can browse or accessing a specific site collection in SharePoint 2016, you have to configure the Site Collection Quotas and Locks in Central Administration by doing the following:

    Disable site collection SharePoint 2016
  2. In Site Collection Quotas and Locks, Choose the site collection that you would like to prevent all users to access,
  3. At Site Lock Information, you have 4 options to manage the lock status for the specified site collection as following:
    • Not locked to unlock the site collection and make it available to users.
    • Adding content prevented to prevent users from adding new content to the site collection. however, updates and deletions are still allowed.
    • Read-only (blocks additions, updates, and deletions) to prevent users from adding, updating, or deleting content.
    • No access to prevent users from accessing the site collection and its content.
