How can I ensure that my sales department head is only allowed to search the business communication of the sales team and nobody else?

Vaultastic supports multi-level eDiscovery based on user roles, allowing you to control which vaults a user can access. You can configure the department head’s access so they are only able to search the communication within the vaults of their team members. 

Similarly, auditors can be granted broader access to all users’ mailboxes, while IT staff may be restricted from accessing VIP users’ vaults. This ensures that access is precisely tailored to each role, protecting data privacy and maintaining compliance.
