Things to Consider When Selecting Secure Email Gateway Tools

The Level of Security Functions

Every email security gateway should safeguard against malicious email, phishing attempts, and spam. This is not to say that an email security gateway product should only include basic anti-virus, antispam, and anti-phishing features.

Instead, an organization should seek out more advanced anti-virus, antispam, and anti-phishing technology. Malware detection, for example, should employ sandboxing and other advanced techniques to examine files for potentially dangerous behavior. Using signature-based malware detection approaches, such as anti-virus signatures, is no longer sufficient. Email security gateway providers typically provide sandboxing and other advanced features.

Other Security Features Offered by Email Security Gateways

Some gateways merely provide the aforementioned basic security functionalities. However, gateways are increasingly providing additional email-related security features, such as data loss prevention (DLP) and outbound email encryption.

Many firms, particularly larger enterprises, disregard these additional services since they already have corporate DLP and email encryption capabilities. However, adding DLP and email encryption options to an email security gateway for enterprises that do not have these capabilities.

Customizable Features

Although enterprises may not want to spend time customizing their secure email gateway tools, doing so can enhance detection capabilities and the management process by customizing administrator dashboards, gateway reports, and other parts of the gateway.

The requirements for usability and customization of gateway administration differ significantly between businesses. High-risk businesses require a high level of customization to make detection as advanced as feasible, even if this has a detrimental impact on usability.

As essential as they are, it is equally critical for businesses to ensure that they are investing in the right ones that correspond with their objectives.
