The Future of Email Security in the Cloud - And Why You Should Reexamine Your Approach Now

Email remains the most widely used communication method for business. Studies estimate that nearly 125 billion business emails are sent each day – a three percent year-over-year growth since 2015.

Technology writer Chris Nerney explained why email still reigns as a primary method of professional communication in a July 2018 blog: “Email is highly functional. Anyone with an email account can send an email to anyone else with an email address, no matter which client they use. In the business world, there’s a lot of value to that, and it’s probably the main reason why messaging apps, social media and collaboration platforms haven’t yet rendered email obsolete.”

Yet due to its inherent security flaws, email also remains one of the most common attack vectors. In a 2018 survey of IT professionals, GreatHorn determined that the average
organization has three security products in place to combat email threats; however, 40 percent of that same group sees email threats bypass these security solutions and be delivered into inboxes on a weekly basis. Despite email’s tenure and prevalence, few organizations have email security threats under control – even with great manpower and tool investment.

The traditional approach to email security is failing, and the problem is plaguing organizations across all industries. In fact, a LinkedIn survey of more than 1,900 security professionals indicated that email security is a top priority for more than half of organizations. Threats consistently are becoming more sophisticated and slipping past traditional security measures, while the changing technology landscape creates new security demands. As more organizations embrace modern IT infrastructure, they are looking to tackle the challenge with solutions that are just as dynamic as their cloud-based email systems.

This white paper will guide security teams as they reexamine their approach to cloud-based email.
