BACKGROUND IMAGE: rvrspb/Fotolia

Protect your company with email security gateways

Secure email gateways protect organizations by preventing malicious emails from infiltrating company networks. This is accomplished 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 secure email gateways -- whether as a stand-alone or virtual appliance, installed as software directly on the mail server, or in the public or private cloud.

In addition to their standard function, secure email 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.

In this buyer's guide, readers will learn the basic architecture of how email security gateways protect enterprises, including the hybrid approach and on-site appliances. It also lays out what organizations need to know before making an investment in the product by listing criteria and use cases, and presents direct comparisons and overviews of some of the best email security gateways on the market today.
