Email security

Even with all the modern technology evolving in the business world, emails are still one of the most relied on mediums of communication. It is critical to ensure the security of email, as it could lead to the downfall of your company.

In this article we will discuss Phishing attacks and what we can do to avoid them.

Phishing attacks

As more businesses transition to online platforms, this opens areas that can be exploited. A phishing attack occurs when an attacker impersonates a friend, a business, vendor  or employer to trick the victim into opening either emails or text messages. An example email could be:

“This email has been automatically generated by…,

Your company has recently breached the terms of GDPR (General Data Protection Regulation). Download this document to view the full extent of this breach *insert link*.”

 This email would contain a malicious link which could contain a virus, keylogger or other software that an attacker could use to access your companies’ data.

Types of phishing attacks:

Spear Phishing

This type of attack focuses on a specific user within the company, such as  a finance person. This would give the attacker broad access to company data. Attackers will normally target people that have access to multiple departments to allow them to gather as much information as possible.

Whale Phishing

Attackers use this method to target the bigger names within a company, such as the CEO. They can then use the CEO’s email address to easily pose as a trusted source and infiltrate different areas of your business.


This type of attacks happens via telephone. Attackers will phone the target and pose as a banking or Microsoft employee to steal information. This could lead to attackers gaining financial/company data.

Mitigating Phishing attacks:

 Email Protection Software

This is an overlooked step in detecting suspicious emails. Certain types of software can be used to identify and flag phishing emails. It can also be used to detect spam and other malicious emails. This is a good first step for a business to implement as it brings awareness to users of what to look out for.

Train your colleagues

The most important/most overlooked way to stop phishing attempts. Spending time to train your colleagues and make them aware of different attacks is a crucial step in preventing attacks like this from coming to fruition. Training days are best to be held bi-monthly and should contain an element of interaction. It is much easier to spot phishing attempts when you have been exposed to them.

3: Choosing the right phone platform
