As organizations explore SD-WAN as a way to make their networks more configurable and efficient, some will inevitably have questions about the technology’s security.In general, there are two schools of thought on SD-WAN security. One suggests that because many SD-WAN vendors use IPsec to protect data in transit, the technology is therefore secure. The second suggests that SD-WAN is not secure because it doesn’t scan network traffic for vulnerabilities before it’s sent. As with many things in life, there’s a bit of truth in both views. SD-WAN typically uses encrypted tunneling technology like IPsec to protect traffic from prying eyes and man-in-middle attacks while it’s in transit.
