Top 3 Email Security Practices Every Business Must Observe

Companies around the world rely heavily on email to conduct their day-to-day business activities, such as invoicing customers, communicating with suppliers, and collaborating internally. These days, email is considered the most significant communication tool by many businesses. However, email communications are not always secure.

Hackers can imitate domains to make their emails look like they come from trusted contacts, distribute spam and malware via email channels, and use social engineering to deceive users into making payments or logging into fake accounts. All these can compromise the sensitive data of a business and lead to significant losses.

Specifically, businesses should be aware of malware attacks, since they have been on the rise in recent years. In fact, malware, ransomware, and viruses affect hundreds and thousands of businesses every day. According to research, ransomware attacks alone increased by 134% in 2021 and are expected to continuously increase in the years to come.

As such, it has become necessary for businesses to have extensive email security in place to protect themselves against malware and other forms of cyber scams. They can do this with the help of IT support outsource services and by adopting effective email security practices. Read on as this article discusses some of the most important email security practices that every business should observe in this day and age. 

1. Implement Robust Email Defences

Implementing robust email defences is the first and most essential practice that businesses of all sizes should observe. Putting in place robust email security, such as a Secure Email Gateway (SEG), enables companies to stop malware threats and phishing emails from reaching the inboxes of their employees. These email security services are often utilised as cloud services situated in front of your email network, filtering emails to eliminate graymail, spam, and other kinds of harmful email.

The advantage of having robust email security in place is that companies can guarantee that their users are protected from obvious malicious email threats. SEGs will block email threats from being delivered and prevent the success of phishing attacks that aim to deceive users into giving up account information or making payments. They also give businesses more visibility into email threats, with email account management and complete reporting for all their users.

2. Encrypt Email

Email encryption is another crucial email security practice that companies should follow to protect their users and business data. It is necessary for businesses of all sizes to be encrypting their emails.

The primary purpose of encrypting emails is to ensure that only intended recipients will receive the emails, with all the information they contain being protected. They typically function by asking users to log in to see encrypted emails. Basically, this means that email senders are given more control over the email, such as having the ability to revoke access to emails that have been sent to the wrong people and to stop emails from being sent.

3. Adopt Anti-Virus and Endpoint Protection

Enforcing endpoint anti-virus protection across all work devices is one excellent practice that businesses should follow to strengthen their email security. This is an essential step in combatting malware and ransomware, as it will prevent them from being delivered via email and from infecting endpoint devices. Email is typically used by hackers to deliver malware in the form of infected attachments and links to websites that contain harmful downloads.

Fortunately, anti-virus solutions have the ability to scan files and websites to ensure that they are not malicious and to help users remove any malware that can be found on their systems. Endpoint protection solutions also offer a management interface that enables IT departments to track all devices within a business network. They may utilise this to monitor access and usage and to run system scans. In Singapore, Trend Micro business anti-virus solutions are widely implemented to effectively combat malware.


Putting in place comprehensive email security is undoubtedly necessary for businesses today to protect themselves against malware and other forms of cyber fraud that could cost them millions of dollars. Over 90% of malware threats start with an email. Therefore, having solid email security in place means that a company can keep its business data secured from a great number of potential cyberattacks.
