My understanding is that ZIA has 3 ways to do a connection to the ZScaler node. One is through the connector/app, another is through an IPSec VPN tunnel and the third is through a GRE tunnel.
However, I have come across someone saying that outbound connections from the connector/app are actually sent via GRE. Can someone confirm or correct that please?
And if that is true, how is the data secured when in transit?
