Cloud computing has revolutionized the way many organizations manage their IT, but it’s not without its critics and concerns. Perhaps the greatest concern for many has been entrusting mission critical data and functions to a third party. This was more valid during the earliest days of cloud computing, but today, most reputable cloud providers have resources and security that exceeds even the most sophisticated on-prem datacenter.
Since Microsoft Office 365™ is hosted in the cloud, subscribers benefit from numerous cloud security measures such as physical security, data encryption, redundancies and regular back-ups. Microsoft® offers Azure™ customers additional options such as Enterprise Mobility + Security to protect and manage user access and devices, and there are also protections available within Office 365 itself.
The two most popular Office 365 subscriptions for enterprise customers are Enterprise E3 and Enterprise E5. E5 comes with two notable security bundles which are not included with E3 or elsewhere. They are Cloud App Security and Advanced Threat Management.
Office 365 Cloud App Security, previously known as Advanced Security Management, provides insight into suspicious activity in Office 365. Once suspicious activities are discovered, Cloud App Security lets administrators define policies to trigger alerts, monitor the way in which Office 365 data is accessed and used, suspend suspicious user accounts, and require users to log in again after an alert has been triggered.
Advanced Threat Intelligence is a collection of threat intelligence data and tools which has been designed to analyze Office 365 environments and proactively find and eliminate threats. It monitors user activity, authentication, email, compromised devices and security incidents.
Advanced Threat Management and Cloud App Security are both included with Office 365 Enterprise E5, but may be purchased separately for other Enterprise subscriptions.
