What is email encryption and when is it needed?

Despite what people think, encryption isn't that complicated. Encryption could be defined as a system of complex mathematical algorithms that encode user data so that the intended recipient can read it. Put simply, encryption is a tool that enhances the security of a message or a file by scrambling content.

The idea behind encryption isn't that different from kids coming up with secret code words and other discreet ways to communicate that only they can understand. Essentially, it is like sending secret messages between parties that would be impossible to decipher without the proper codes or keys.

Now take this concept and apply it to email. On May 2018, in a General Data Protection Regulation (GDPR)-related phishing scam, hackers took advantage of the flood of emails being sent out by the new European privacy legislation and tricked users with emails claiming to be from AirBnb. According to reports, attackers appeared to be targeting business email addresses.

When and why should you use email encryption?

A hacker could gain access to important company documents, project plans, accounting information, and login credentials for a server just by brute-force attacks. That in itself is dangerous because it could lead to the theft of sensitive data. Here are the key benefits of having encrypted email:

Protects sensitive information and data

Business emails between you, your employees, and clients should remain private and confidential, which is why it's imperative that only the intended recipients get to see sensitive and valuable information. Using encryption prevents hackers from easily obtaining them.

Cost-efficiency

With an integrated encrypted email server, there's no need to purchase additional software or fees per user because all essential features for encryption are already included in the email service.

Time-saving

Since your provider will handle all the legwork, you can save time by avoiding the additional steps to ensure email security. In the past, employees would have to resort to using multiple programs just to secure their connection.

Avoid spam

Besides being annoying, spam attachments could contain malware that hackers use to gain access to your device or system. In late July throughout August 2018, waves of spam emails were detected delivering PyLocky ransomware, a type of crypto-ransomware that could bypass even machine learning tools. Encrypted email contains a digital signature that authenticates incoming emails.

Protecting your business’s communications

To achieve the highest level of protection, you should proactively secure your network and endpoints, not only from new email threats but also from improved older threats. The benefits of email encryption are well known and with this added security feature, you can gain the confidence of your clients and employees and ultimately focus on running other important functions in your business.
