We have a Security concern: In same datacenter, if other droplets have “promiscuous mode” enabled, can they listen to my packets going through my VPC private network ??

  1. If Yes they can listen, then I will encrypt all packets even in my VPC private network.
  2. If No they cannot listen in “promiscuous mode”, then I will trust digital ocean VPC private networking and avoid encrypting through my private VPC network. As this is serious security concern, pls explain in brief how do you stop other droplets listening to my private networking packets using “promiscuous mode”

Hi there @jazzshop222,

With the new DigitalOcean VPC networks, your resources are completely isolated from both other customers and other VPCs on your own account. See here for more details:
