The 5 Biggest Mistakes Businesses Make Around Email Security

In today’s digital age, email remains a primary communication tool for businesses worldwide. However, with increasing reliance on electronic communication comes an elevated risk of security threats. Unfortunately, many companies make critical errors when it comes to protecting their email communications. Here are the five biggest mistakes businesses make concerning email security:

1. Complacency

Believing that a cyber-attack “won’t happen to us” is a perilous mindset. Small and medium-sized businesses sometimes operate under the misconception that they’re too insignificant to be targets. The reality is, attackers often perceive smaller businesses as easy prey, primarily because they’re less likely to have robust security measures in place.

2. Weak Passwords

The humble password remains the first line of defence against unauthorised access. Yet, many users’ resort to easily guessable passwords like “123456” or “password.” Without enforcing strong password policies (including regular changes and the use of alphanumeric combinations), businesses leave a gaping hole in their email security.

3. Lack of Encryption

Sending sensitive information via email without encryption is like sending a postcard through snail mail – anyone who intercepts it can read it. Encryption scrambles the content of the email, ensuring that only the intended recipient with the correct decryption key can read its contents.

4. Phishing Unawareness

Phishing attacks, where attackers masquerade as trustworthy entities to steal sensitive information, have become increasingly sophisticated. Businesses that fail to educate their employees about these threats and how to recognise them are at a significant risk. A single click on a malicious link can compromise an entire network.

5. Not Updating Antivirus Software

Running outdated security software, or worse, not using any at all, is a recipe for disaster. Cyber attackers continuously evolve their methods, and security software providers update their tools to counter these threats. Failing to regularly update these tools renders them ineffective against newer threats.


Email security is paramount in our interconnected world. By addressing these common mistakes and investing in robust email security measures, businesses can significantly reduce their risk of cyber-attacks and ensure the safety of their critical communications. Remember, when it comes to cyber security, proactive measures always outweigh the consequences of reactive remedies.
