Restricts user to some contacts/leads/tickets only

Restricts user to some contacts/leads/tickets only

Hello,

We have a Zoho CRM Plus running fine with our organization.

We will doing a partnership with another company. We would like to allow us to use our CRM by creating a new user but we doesn't want them to see our contacts/leads/campaigns/tickets but only their.

I search myself with the roles and profils settings but cannot find something to restrict only some data by filtering them.

I think the right answer is to build another CRM right ?

Thanks in advance for your support.

Regards.
