The best email security gateways: A buyer's guide

Learn how to buy and procure email security gateways that protect enterprises from emails that violate policy and have malicious intent, such as those carrying malware, spam and phishing attacks.

Introduction

Email security gateways secure organizations by preventing malicious emails from reaching their destinations. They generally do this by quarantining or blocking inbound and outbound emails that contain malicious content -- such as malware, spam and phishing attacks – or that violate enterprise policies. Nearly every organization can benefit from the deployment of an email security gateway -- be it as a standalone or virtual appliance, or installed as software directly on the mail server, local server in the data center or in the public or private cloud.

In addition to its standard email security function, these gateways often deliver additional benefits to organizations, including compensating for weak or missing client security controls and delivering email encryption services to protect the confidentiality and integrity of emails in transit. Some email security gateways even offer data loss prevention capabilities to thwart the -- accidental or deliberate -- leakage of sensitive information via email messages.
