The Possibilities of Email Encryption

Geoff Bibby

The email inbox remains one of the primary attack points for hackers. And for good reason: From login credentials to intellectual property to communications, the most sensitive information a company owns funnels through email dozens of times a day, every day.

Email security with targeted threat protection keeps this tool safe from the latest attacks, but email encryption is an added layer of protection for your data. And while the need for encryption may be generally understood by organizations, there are still a few misconceptions surrounding it that can make efforts toward comprehensive protection feel more difficult than they actually are.

Fortunately, organizations with better understandings of email encryption tools and the simplicity they can offer both companies and users can bolster their cybersecurity efforts and protect their most valuable commodity (information) this year.

The Misconceptions Around Encryption, Dispelled


• Email encryption doesn’t have to be difficult to implement or use. Wanting to streamline workflows and increase productivity, users can ignore encryption efforts that require extra steps or feel burdensome, causing sensitive emails to travel in and out of your network with minimal (or no) protection. We know, though, that the best encryption tools can also be the most intuitive, strong, and automatic, requiring both the sender and receiver to take few, if any, steps to ensure that sensitive information is secure.

• Today’s email encryption market is dynamic. Some users may still rely on email encryption solutions that are outdated or ineffective, thinking that better solutions haven’t been created. The opposite is true. In regard to accessibility and usability, email encryption has drastically advanced, which is no more evident than in a user’s experience on a mobile device. Overall, and given the solutions on today’s dynamic email encryption market, it now takes less time, training, and trouble than ever to ensure that every sensitive email is encrypted and accessible across any device.

• Transport Layer Security (TLS) is a good start to securing email communications, but email encryption goes a step further. Webmail providers like Google have recently reported on the importance and broadening application of TLS. While it’s true that TLS is an important step toward protection, TLS itself has gaps that limit its effectiveness as a comprehensive email security strategy. Mandatory TLS is challenging to implement and manage on an ongoing basis, and it can cause business disruption if emails cannot be distributed securely. Opportunistic TLS is convenient but exchanges emails no matter if security cannot be achieved. Enterprise users wanting complete protection need an email encryption solution that leverages TLS and failover options to provide the best and most comprehensive security.

The Zix Strategy


An email encryption platform should be as easy, comprehensive, and seamless as possible, which is why we created ZixEncrypt: to offer organizations the right tools to alleviate user efforts and uncertainty so that security is automatic rather than optional. In this way, administrators and users won’t consider it a burden, and sensitive messages will be reliably encrypted even if users make mistakes.

Don’t let misconceptions cloud your approach to a comprehensive email protection strategy. Companies that understand the possibilities of today’s solutions can better manage their risks in this cyber landscape, rendering greater security for more peace of mind.
