Over 90% of cyberattacks begin from an email. Given how often individuals and businesses utilize email, this percentage is scary. These attacks have cost organizations an average of $13 million in damages, which will continue to grow.

Email security threats evolve regularly, and businesses must keep pace more than ever. Email addresses are one of the most high-value data assets for cybercriminals since they can grant them access to many of their targets’ other accounts, most importantly, financial accounts.

Cyberattacks no longer remain a question of ‘if’; they now simply become ‘when.’ Unfortunately, it’s just a matter of time until your corporate or private information gets hacked. While conventional antivirus software or firewall is an excellent start to prevent cyberattacks, they may not be enough.

With the increase in email usage over the years, there has also been an increase in cyber threats. So, email security should be at the top of your list of priorities. Encryption is one technique that has proven to be a game-changer for many industries.

Althought it may seem counterintuitive, as a small business, you face heightened cyber risk. Cybercriminals recognize that small businesses often lack the resources and expertise required to defend against cyberattacks, and readily exploit these weaknesses.

Many people are likely unaware of how large a cybersecurity vulnerability their email represents. This is not to disrespect the excellent work of our favorite communication tool. Still, given that email was never designed to be secure, we should use it only in addition to other forms of communication.
