What is a Secure Email Gateway?

Secure Email Gateways or shortly SEGs are an email security solution that awaits on an email's path from the public internet to the corporate email server. It inspects email traffic for malicious content before it reaches the corporate systems.

Organizations should protect themselves from email cyberattacks

Many organizations apply a Secure Email Gateway as part of their email security system. Before an email enters or exits their employees' inboxes, it first needs to pass through a Secure Email Gateway, which checks whether the incoming emails show any signs of a malicious message or content. If it detects red flags, like typical signs of email phishing, it won't deliver the email. It can also scan outgoing emails for sensitive or confidential information.

How does a Secure Email Gateway work?

Secure Email Gateways detect emails with unwanted content like spam, phishing links, or malware. Once a Secure Email Gateway detects a potential email threat, it blocks the email from reaching the recipient. This slims down the odds of a company falling victim to an email cyberattack. Due to the fact that the malicious email is not even delivered, the recipient cannot interact with it and potentially click on a malicious link or download a malicious attachment.

Common features of Secure Email Gateways

Filtering spam

A Secure Email Gateway focuses mainly on clearing out spam emails. It looks for common patterns found in spam messages and blocks them. Depending on the specific vendor and solution, it can also include a feature for employees to mark an email as spam.

Protecting from malicious content

Secure Email Gateways can find some elements of a phishing email such as malicious links or attachments. Despite this, sophisticated phishing attacks can pass SEGs, delivering the email.

Preventing data loss

Outgoing emails are scanned with a Secure Email Gateway too. It looks for sensitive information in emails that are getting sent to unauthorized recipients.

What are the dangers of using Secure Email Gateways?

Even though Secure Email Gateways are a widely used email security defense tool, they haven’t kept up with all the different ways that email attacks can happen. SEGs look at the basic and traditional signs of suspicious emails. This means that they don’t catch advanced dangerous attacks, like social engineering attacks that are often used these days.

While an SEG does a great job of filtering spam and large-scale email attacks, it’s not equipped to handle highly-targeted phishing and social engineering attacks. 

So what can you do to protect your organization from advanced attacks?
