Read Reviews Of The Best Email Security Gateways

What are Secure Email Gateways?

Secure Email Gateways block email based threats before they enter a network. They protect businesses from spam, viruses, malware and denial of service attacks. The gateway scans all incoming, outbound and internal email communications, including attachments and URLs for signs of malicious or harmful content.

Email Gateways will also offer protection from social engineering attacks such as phishing, or business email compromise. The gateway can check the domain of incoming emails, as well as scan for suspicious content within the email, to stop harmful content from coming into the network. Emails that have been marked as malicious are quarantined or rejected. Some systems allow the quarantined emails to be accessed by admins if necessary.

Alongside blocking incoming threats, Email Gateways will also scan outgoing content. This can help protect businesses from data loss. Many Email Gateways will provide Email Archiving functionality, which stores emails for legal compliance and data management. They will also provide business with Continuity features, which mean that even if their email network goes down, they will still be able to access their emails. Email Gateways will also provide businesses with a management dashboard and a range of reports and analytics. These give businesses visibility into all email traffic in a network. This is important for businesses to gain insights into their network security.

This category covers cloud based secure email gateways. All of the vendors listed in this comparison are able to protect on-premise mail servers like Exchange, GroupWise, Notes, or Zimbra plus cloud based services such as Office 365 and Google G-Suite.
