In a new IDC infographic sponsored by Vade Secure, IDC reports that although cloud email adoption grew to more than 70 percent in 2019, businesses are lagging when it comes to cloud email security deployments.

The shift toward cloud email has inevitably broadened the attack surface, and because cloud email security adoption hasn’t kept pace, businesses are vulnerable to advanced email threats.

Businesses Overwhelmingly Choose Office 365

Although Microsoft essentially owns the market in cloud email—47 percent of cloud email deployments in Office 365 in 2018—it’s not the only area where Microsoft reigns supreme. For four straight quarters, Microsoft has been the #1 impersonated brand in global phishing attacks. This makes Office 365 users a prime target for advanced threats like phishing, spear phishing, and malware.

Existing Email Protection Isn’t Enough to Stop Advanced Threats

With many businesses relying on Secure Email Gateways (SEG) for email protection, attacks continue to slip past Office 365’s native security solution, Exchange Online Protection (EOP). Failing to address the weaknesses of native protection puts businesses at risk of joining the growing number of businesses that have reported ongoing Office 365 attacks. To protect users, businesses using Office 365 need complementary protection.
