I currently run Barracuda Spam Firewall Model 300. We use our current appliance for the following:
Spam Filtering / AV Filtering. Inbound and Outbound
E-Mail Encryption using keywords in the subject and body of the e-mail message.
I need to upgrade/replace the device is because of admin permissions. The appliance seems to have only 3 types of users: Domain admin, helpdesk, and user. We tried using the helpdesk user accounts, but they do not have the required permissions to make changes to the appliance. We’re not allowed to use the domain admin permissions because domain admins are able to view messages leaving the appliance. Do you know if there’s a better model Barracuda has that has better permission levels for IT support, or a better a spam filter appliance that will block spam (obviously), encrypt outbound messages, and have more flexible permission levels that I can assign to IT support?
