Encryption—a process used to convert data from its original form to a format that is unreadable and unusable to anyone without the information needed to reverse it—is often meant to prevent third parties from viewing or accessing data.
With the average cost of a data breach at $3.62 million, encryption has been shown to reduce the costs of an incident, according to a study from IBM Security and the Ponemon Institute. The Department of Defense recently announced that it will begin using a stronger email encryption technology starting in July 2018.
"If you're not making use of encryption with your email, you should be," wrote TechRepublic contributing writer Jack Wallen. "More and more sensitive information is being passed between recipients, much of which is being sent in plain-text form. That means one thing: anyone can read it. To thwart that, we turn to encryption technology that promises to obfuscate that sensitive information; and it works."
Despite the benefits, the majority of CIOs said that they are not using encryption for email messaging. When asked "Does your company encrypt emails?" seven members of our CIO Jury panel said no, while five said yes.

"I think we need 'critical mass' before we start doing this, and we certainly aren't the DoD," said Simon Johns, IT director at Sheppard Robson Architects LLP.
At Shealy Electrical Wholesalers, "long term, we want to implement it, but we have insufficient time and resources at present," said Jeff Focke, director of IT.
"We assume email is insecure communications," said Jeff Kopp, technology coordinator at Christ the King Catholic School.
On the other hand, Dustin Bolander, CIO at Technology Pointe, said his company has been encrypting emails for the past few years "due to regulatory requirements."
Others are newer to the technology. "We just started the process, using Microsoft tools," said Michael Hanken, vice president of IT at Multiquip Inc. "First impressions and feedback look very favorable."
The national conversation around encryption came to a head with the 2015 controversy between Apple and the FBI, in which Apple refused a court order to unlock the iPhone used by the San Bernardino shooter. The Justice Department eventually dropped its case against Apple, as it unlocked the phone with help from an outside party. Since then, a number of states have seen similar cases.
For the average user, encryption can be difficult to figure out, Wallen wrote. But companies can try and simplify encryption for email purposes, using tools such as SecureMyEmail.
