Email Threat Protection – Methods to protect your Business

In a previous article we wrote about how to protect your business from malicious email attachments. Today, we’ll be looking at additional methods you can put into place to minimise the risk of installing email threat malware onto your business IT systems.

How email malware could harm your business

Once the malware has made it on to your business systems, it can be difficult to notice until it’s all too late. The impacts that malware can have on your business can be devastating. Here are five ways in which malware could harm your business:

  • It could access sensitive data such as passwords, online banking information, employee bank details, or sales information (e.g. credit card details).
  • It could gain access to your website, blog, or social media channels and post malicious, spam, or derogatory content.
  • It could erase or wipe your computer hard drive which can be disastrous – particularly if it’s not regularly backed up.
  • It could send out spam emails (possibly also containing malware threats) to all of your clients and customers.
  • It could scrape details about all of your customers or email subscribers which could then be sold on for profit or published online to show the world how insecure your company is – that sort of damage to your reputation is hard to recover.
