Office 365 Connectivity Principles

To optimize Office 365, Microsoft recommends:

Identify Office 365 applications

NetFoundry's API integration with Microsoft identifies the Office 365 applications, separating them into the optimize, allow and default groups, as defined by Microsoft. NetFoundry provides this integration as part of the NetFoundry NaaS service - making it simple for businesses.

Enable sites to route the Office 365 applications via local Internet connection(s)

The NetFoundry web console enables businesses to easily route the optimize and allow O365 applications directly to the local Internet gateway, without any manual configuration. The NetFoundry console will even warn administrators if the Optimize or Allow Office 365 applications are not configured to be routed directly over the Internet. This eliminates expensive backhaul, which can add impairment and compromise visibility and control. Instead, the Office 365 applications take advantage of Microsoft’s Front Door infrastructure (over 130 entry points for O365), which results in the lowest latency between site and the Microsoft network.

Ensure that O365 apps bypass potentially intrusive inspection and proxy elements, which provide functions already built into Office 365

While this infrastructure is necessary for many apps, it does not add value for Office 365, and often adds latency, impairment and risk. NetFoundry therefore does not inspect Office 365, while simultaneously applying NetFoundry's Zero Trust solution to other applications at the branch site.

NetFoundry's Zero Trust, least privileged access security paradigm enables the business site to remain secure.  Only Office 365 and specifically authorized and authenticated applications are permitted across the NetFoundry private network Fabric; any other data is denied via an integrated software firewall. This empowers businesses to securely route Office 365 traffic directly to the Microsoft network over the Internet, without subjecting it to any potential impairments from third party on-premise or cloud-based security infrastructure.
