The email firewall will also protect against social engineering attacks such as phishing or corporate email intrusion. Firewalls can check the domain of incoming emails, as well as scan for suspicious content in emails to prevent dangerous content from entering the system. Emails marked as dangerous will be quarantined or rejected. In addition, some systems will allow administrators to access quarantined emails if necessary.

Besides blocking incoming threats, email firewalls also scan outgoing content. This can help protect businesses from data loss. Some email firewalls will provide email archiving. This function stores emails for legal and data management purposes. It also provides businesses with continuity features, which means that when a business’s email network is disrupted, they can still access their email. Mail Gateway also provides businesses with a management dashboard and a range of reports and analytics. Helps businesses have an overview of all email traffic in the network. As a result, they have a deeper understanding of their network security system.
