multiple companies
Many companies appoint a single staff member to funnel tech suppor through. Under this model, that person needs admin access to see all the tickets created for their company but granting admin access allows access to all tickets.
Current workaround is to assign that user staff rights but only to a specific category which you create with the company's name.
The problem with this is that the full list of category's (aka companies) is viewable by each Staff user. Finding a way to block all "category's" except the one restricted to the user is necessary.
This scenario is also applicable to a company that has IT staff on site seeking support from a third party using HESK.
