We deploy it for a government organization to protect against spamming and the blacklisting of the email server. 

We are a technical services company and we work with many different solutions, including the Sophos Email Appliance. We currently have a couple of customers who use Sophos.

This solution is for the secure delivery of inbound email. There are various use cases including checking email against spam, DNS or configuration related issues, and spoofing-related security issues. It also checks URL in emails, as well as for malicious attachments. All of these things are checked before the email is delivered to the user.

We have a Sophos XG appliance and licensing for email, virus, anti-spam, and some other email features. So the primary purpose of the product is our primary use case.

We primarily use the solution to control spam.

We primarily use the solution for messaging, security, spam protection, and for phishing protection as well as one-click linking protection.

Our primary use for the Sophos Email Appliance is messaging security. We implement this solution for our customers.
