Do you know when the first email was sent?

It was 1971 when Roy Tomlinson sent the first email across a network.

Almost 40 years later, Verizon’s 2019 Data Breach Investigations Report called out email phishing as the main cyber security threat facing enterprises in the digital world. In line with that announcement, Gartner’s Fighting Phishing Report, found that 90% of cyber threats against enterprises start with email, making email the No.1 attack vector against enterprises.

Enterprise email security is a mature market, which poses the obvious question of why cyber criminals are still using emails as an attack vector. Are email security solutions ineffective, or are the adversaries just very talented when it comes to circumventing email security controls?

In recent years, we’ve seen a rapid shift to cloud based email providers – whether that’s moving existing office suite capabilities to the equivalent cloud based office suites (think an on-prem Microsoft Office and Exchange moving to Office 365), or new organizations starting with a cloud installation.

Private end users don’t spend any time worrying about the risks involved in relying on the default security built into cloud email providers, but there are inherent vulnerabilities in cloud office suite solutions that could keep any CISO up at night.

So what’s a cloud native organization to do? How can you make sure that you don’t fall victim to the ‘click-bate’ that’s responsible for 90% of enterprise breaches?

As the new decade dawns, IT managers and CISOs have an array of email security options to choose from, but picking the right one can be a daunting prospect.
