The Most Common Threats To Email Security

Email is a communications tool that the vast majority of individuals and businesses use on a daily basis. Every day the average company sends thousands of emails, and within those sent and received emails is sensitive data and information that must be protected at all costs.  But when a business looks into purchasing an email security system, what is it exactly that they are protecting themselves against? Here are the most common threats to email security in 2013.


Every single one of us has experienced spam mail at some point, and it’s no wonder considering that 66.5% of all emails sent are spam. While a great deal of spam mail is simply annoying and can slow down work productivity, many spam emails will contain malicious links. Once opened, these links can contain dangerous viruses, malware and spyware that can bring a computer system down and can compromise the security of important data.  A common tactic that spammers use is to focus emails on topical and popular current events that will interest the reader and encourage them to click. The average user may or may not be able to detect a spam email, but a robust security system such as Mimecast email security will 100% safeguard users from the threat of spam.


Imagine if a third party was able to record every single click and keystroke that you make on your company computer. This is a very real threat called Spyware. A successful Spyware installation from a third party could expose confidential data and plans that should be kept secure. Spyware is usually bundled into shareware and freeware computer programs that can run without the end user being aware of it. This major threat to email security can be curbed by security systems that employ a proactive approach and detect spyware programs before they are downloaded.


Phishing is often thought of solely as a threat to individuals, but there have been multiple smaller businesses that have been targeted by phishing attacks. A phishing attack is essentially a form of financial fraud. In phishing emails, people will pose as legitimate organisations such as HRMC in order to extract business and financial information that can easily lead to fraud on a large scale. A sophisticated email security system will detect the patterns of phishing attacks and be able to significantly minimise, if not entirely eradicate, the threat of phishing.


Malicious viruses can be sent across emails in a second and bring down complete systems in just as little time, allowing the attackers access to sensitive information. Viruses are often spread in a very sophisticated way, disguised as perfectly harmless emails, and this is why a robust email security system is essential for any business. A security system will scan every email for potential viruses proactively, meaning that the issue is raised and brought to the attention of the end user before any serious damage is inflicted.
