HOW TO MORE THOROUGHLY PROTECT EMAIL IN EXCHANGE ONLINE

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 .
