On its own, an email account has no means of protection from spam, phishing, or other email-borne threats. It’s a simple passage from sender to receiver. There are few measures to keep tabs on what’s in the email. <\/span>However, more and more email services include filters that automatically sort meaningless emails away\u2014case in point: The “Spam” folder. <\/span>That said, there are heavy-duty forms of this filter. <\/span>Secure Email Gateways <\/span><\/strong>(SEGs) are third-party software or devices that identify unwanted emails.<\/span><\/p>\n

With SEGs, spam, phishing attempts, and hidden malware can be detected and removed. This, all without the receiver ever having to open such an email. In this article, we dive into the details of these email barriers and explain what they are and what their purpose is. <\/span><\/p>\n

So, <\/span>what is an email gateway<\/span><\/strong>?<\/span><\/p>\n

What Problem Does a Secure Email Gateway Solve?<\/span><\/strong><\/h2>\n

At its core, an SEG aims to resolve the annoyance of spam emails of any kind. There are different levels of security and thoroughness depending on the user’s needs. But as a whole, SEGs reduce the risk of unwanted or malicious emails being opened by the end-user.<\/span><\/p>\n

For organizations, this can be highly beneficial. Spam and phishing cyberattacks target businesses and organizations far more often than individuals. Email accounts often become bloated with unnecessary or outright intrusive emails.<\/span><\/p>\n

For organizational domains, this becomes even more troubling. It’s already hard enough to manage a single email account that gets dozens of emails per day, let alone business email accounts attached to one domain.<\/span><\/p>\n

SEGs reduce this pile-up by eliminating mass amounts of unwanted emails that don’t fit the given criteria. This way, there’s no manual component of having to comb through spam, wasting hours.<\/span><\/p>\n

How Do Email Security Gateways Work?<\/span><\/strong><\/h2>\n

As mentioned, SEGs offer a greater level of security than your typical email filter. Organizations receive many more infected and malware-heavy emails than the average individual. To prevent these emails from ever being opened and delivering viruses, an SEG must detect them before they land in the inbox.<\/span><\/p>\n

SEGs do this by staying updated with the known patterns, methods, and strategies that cybercriminals use to hide their infected emails. There’s no real way of knowing what precisely an email holds without opening and reading the information inside. Still, these secure gateways can detect, open, and disarm emails in a sandbox area before delivery completion.<\/span><\/p>\n
