Download whitepaper here
Microsoft has been marketing remotely hosted / cloud-based versions of Exchange and other elements of its Office suite for many years, but has gained serious traction with the current iteration of this effort – Exchange Online and Office 365TM. As shown in Figure 1, a substantial proportion of organizations whose users are today served by on-premises versions of Exchange will be served by some version of Office 365, whether email only through Exchange Online or by some combination of elements offered within Office 365.
There are several important points presented in this white paper, the focus of which is Exchange Online:
• Exchange Online is a robust and capable offering that can significantly reduce an organization’ s cost of providing email and collaboration services to its users.
Even large enterprises can realize significant cost savings and other benefits from the use of Exchange Online.
• However, as with many cloud-based applications, there are limitations with the security capabilities provided along with Exchange Online. For example, the DLP capabilities are less mature and less capable than what are available from some other enterprise DLP solution vendors, there are limitations in the filtering of spam and malware, limitations in detecting and remediating targeted and more advanced threats, and a more difficult experience for mobile users and for those who rely on encryption.
• Consequently, enterprise decision makers migrating to Exchange Online should evaluate and seriously consider the use of third-party email security, advanced threat detection and data loss prevention solutions to supplement or replace the security services available from Microsoft for Exchange Online and Office 365.
