As organizations migrate email to Office 365, their cloud-first strategies are calling into question the efficacy of their legacy Secure Email Gateway (SEG).

Particularly with new built in antivirus, anti-spam, data leak prevention, archiving and other capabilities build into the native O365 architecture, is the SEG still needed?

This white paper explores the new security features of Office 365 and the benefit of paring it with the new Secure Email Cloud to stop modern threats such as spear phishing, business account compromise and email account takeover.

Introduction to a Cloud-First World
The Migration of Workloads and Security to the Cloud

When Marc Benioff launched the “no software” movement on the eve of the dot-com bust in 1999, there was little indication of the tectonic shift to come across the business IT landscape.

While “Googled” became a word, “elastic cloud” compute and storage became the norm and organizations turned to Infrastructure-as-a-Service (IaaS) as prices for cloud hosting dropped precipitously. Organizations worldwide could now place workers and facilities just about anywhere around the globe and adjust IT strategy and workloads on the fly.

Platform-as-a-Service (PaaS) has since emerged as a compelling way to free organizations from decades of layered on-premises systems, improve security, and deliver integrated services.

As the dust began to settle, what started off as an ingenious way to eliminate IT capital expenditures, alleviate overhead, and accelerate software deployment morphed into a new way of business.

IaaS, PaaS and Software-as-a-Service (SaaS) turned out to be ideal enablers for an increasingly virtual and mobile workforce. Equipped with the ability to avoid up-front time and cost and to quickly phase out inefficient services, business agility improved.

Today, just under one-third of overall corporate IT budget goes to cloud services, and the industry is on track to reach about $513B by 20226.

With close to 200M users7, perhaps no SaaS solution illustrates this better than Microsoft Office 365, which didn’t just move to the cloud, but also reinvented the office productivity suite and became more resilient to cyber attacks. Now, there are compelling business reasons to move email security to the cloud as well.
