Some insights to security best practices for SD WAN will be appreciated

Context to your question, are you re-thinking your perimeters with SD-WAN?
We’re seeing a number of scenarios with our customers:

  1. Continue to backhaul traffic and send to the nearest POP to the Internet. At least not immediately to minimize security changes initially.
  2. Adopting security-as-a-service in the cloud such as Zscaler. Customers define the policies and they’ve to ensure that best practices are followed from a governance perspective.
  3. Deploying a single box firewall solution at the remote site. Haven’t seen as many.
  4. Some strictly limit what they can access from the remote sites by building a whitelist using existing infrastructure.
