IPsec is a critical element in building a scalable and secure SD-WAN fabric. The right IPsec is key to making it happen. Robert Sturt published an article title “SD-WAN vs. VPN: How do they compare?”
While Robert tried to illustrate when and how to use SD-WAN vs. VPN,
the objective of this blog is to look deeper into existing IPsec
approaches and challenges in building and securing an SD-WAN fabric, and
how IPsec UDP can help address these challenges. At the end of this
blog, I have included a link to a Silver Peak white paper that provides a
detailed explanation of IPsec options.
