SD-WAN is one of the hottest technologies in the networking space. Being hot, though, doesn’t mean that SD-WAN has a solid business case to support it. Historically, MPLS was the default WAN choice to maximize uptime and ensure predictable network behavior. How can IT executives justify the investment in this technology?

Happy To Announce the Birth of a New Technology – SD-WAN It wasnt that long ago that we oohed and ahhed over the brand-new technology called SD-WAN. But just as were getting used to the toddling SD-WAN, along came yet another even more exciting newborn, the Secure Access Service Edge (SASE). Thats so yesteryear or is it?

Companies evaluating which SD-WAN approach is best for them will have to decide between deploying an Over the Top (OTT) SD-WAN or having their SD-WAN bundled with the underlying network. The decision certainly has a big impact on SD-WANs complexity, performance, and affordability. Is Cato an OTT SD-WAN?
