Microsoft had presentations from their CEO and CIO (all this for a tiny upstart Zscaler, whom is enabling the security from Azure for 365)
OK, since this is the second time you’ve posted this I feel the need to correct it. Zscaler is NOT providing the security, nor enabling the security, for Office 365. Zscaler is but one of a variety of security choices one can choose when deploying Office 365: https://blogs.technet.microsoft.com/onthewire/2017/05/03/off…
First, let’s understand that there are 3 methods to deploy Office 365 on Microsoft’s network:
• Direct Routing
• Proxied Access
• ExpressRoute
Of these, Microsoft recommends Direct Routing due to the efficient, low impact manner of egress, allowing connections to flow direct, using the protocol of choice, this method is the recommended method to connect your Office 365 services wherever it is possible. (link above)
Using Zscaler is only an option if you choose Proxied Access, which Microsoft doesn’t recommend due to potential performance issues, and even then there are security alternatives: Whilst not a recommendation for any vendor over another, Microsoft are working with various vendors such as Zscaler and Bluecoat to help better align cloud proxy products to best practices for Office 365.
So, let’s be careful not to overstate Zscaler’s market penetration.
how Zscaler enabled GE to get rid of their data center and instead, with much more security, use the internet as their network.
Again, let’s not go overboard here. Zscaler is a security solution, not a data solution. Adding security doesn’t get rid of data centers. You still need to store your data! See slide 4 in this Zscale presentation showing their ideal world still incorporates a data center.
What Zscaler is prompting is that their security is good enough and easy enough that a company’s users can access everything over a Zscaler-secured internet and keep them off your corporate network. In most cases, however, you’ll still have that corporate network.
So, yes, it looks like I should do a deep dive on what Zscaler really is and does due to much mis-information being spread out here.
