Encryption of ExpressRoute content

Encryption of ExpressRoute content

Q. Is data sent over ExpressRoute encrypted?

A. No. Since ExpressRoute is a dedicated connection between on-premises and Azure that does not use the public Internet the traffic is not encrypted. If you need encryption you would need to implement this which could be done a number of ways:

  • Application level encryption
  • OS level encryption using technologies such as IPSec
  • Third-party appliance that performs encryption
