What Is Email Security

Email security refers to the different methods and techniques conducted to protect your organization’s email accounts, content, and communication from common threats — such as unauthorized access, loss, or compromise.

Importance Of Email Security

Email is one of the important communication tools that you use in your organization. It empowers you to communicate with clients, potential customers, suppliers, employees, and other businesses all around the world. It is quick, cost-effective, and gets the job done. Most people know how to use email, so it doesn’t require special training.

But because it holds sensitive data, business data, personal information, and is used by everyone, email is also considered one of your organization’s largest attack surfaces. It is used by cybercriminals to spread malware, perform phishing attacks, etc. For this reason, email security should be one of your priorities when it comes to cybersecurity.

Common Email Threats

There are plenty of different methods cybercriminals use for email attacks. Here are some examples:


Malware is one of the most common threats that can be delivered into your organization’s email accounts. This is done through spam emails, which are unsolicited junk emails that are usually sent out in bulk.

These messages typically impersonate legitimate institutions and persons — such as customers, suppliers, or business partners. For this reason, the targeted recipients are tricked into downloading the malicious files, attachments, and malware contained in the message.


Phishing attacks are commonly done through email and are similar to spam. The difference is that phishing email is more customized in nature. Phishing involves posing as a legitimate institution to lure targets into providing sensitive data — such as personal information, passwords, and banking details.

This is usually done through the dissemination of a fake link where unsuspecting individuals can fill in sensitive information. This data is often used to access accounts — which may lead to financial loss, as well as credential and identity theft.

Business Email Compromise

Business Email Compromise (BEC) involves a cybercriminal targeting your organization to defraud it. This scam relies more on impersonation and social engineering techniques rather than malware or malicious links.

The attacker impersonates someone that the recipient trusts — such as high-ranking officials in the company, the CEO, a colleague, or a vendor. It involves studying the victim’s habits and behaviors to create a realistic email. Then they request funds or obtain sensitive information that can be used for future attacks.
