How IPsec UDP Helps Scale and Secure SD-WAN Fabrics

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.

Battery Room Explosion

A hydrogen explosion occurred in an Uninterruptible Power Source (UPS) battery room. The explosion blew a 400 ft2 hole in the roof, collapsed numerous walls and ceilings throughout the building, and significantly damaged a large portion of the 50,000 ft2 building. Fortunately, the computer/data center was vacant at the time and there were no injuries. Read more about the explosion over at hydrogen tools here .
