The explosion in remote work due to the pandemic has resulted in an explosion in SD-WAN products that help remote workers connect to their organizations' networks securely.
Masergy recently announced its SD-WAN Secure Home solution for power users, and there have been others from the likes of VMware and Versa, to name just a couple. This sort of product may not have been a priority for networking services companies such as these at the start of the year, but the new normal means that their time has definitely come.
Seeing the SD-WAN Differences
A possible problem for home SD-WAN vendors, though, is how to differentiate their product offerings, and one obvious way of doing so is through the security offering that goes with it. That's because data security is clearly a key requirement for all home workers, not just those working in banking, finance, government agencies, and other sensitive industries. (It's worth noting at this stage that there have not been any significant reports of hackers targeting home networks or high-powered executives working from home – at least not yet, anyway.)
A by-product of all this interest in home SD-WAN activity is that analysts are making ever more extravagant, yet reasonable, prognostications for the future of the global SD-WAN market. Market researcher Valuates says that the global SD-WAN market was worth just $800 million last year, but predicts that it will grow to $4.1 billion by 2026, at a CAGR of 26.2%.
Meanwhile, Marketsandmarkets expects the SD-WAN market to grow from $1.9 billion this year to $8.4 billion by 2025 at a CAGR of 34.5% during that period. That may seem like a lot, but Adroit Market Research thinks the global SD-WAN market will reach $26 billion by 2028, while Global Market Insights reckon it will grow from $1 billion last year to more than $30 billion in 2026, at a CAGR of more than 60%.

Standing with SASE
If these predictions are even close to being true then securing these SD-WANs is going to be a huge job. That may explain why Gartner is so bullish about Secure Access Service Edge (SASE). In a research paper called "The Future of Network Security Is in the Cloud," the research house predicts that, by 2024, at least 40% of enterprises will have explicit strategies to adopt SASE, up from less than 1% two years ago. It also believes that within five years, at least one of the leading IaaS providers (probably Amazon or Azure) will offer SASE capabilities.
There are other reasons for Gartner's bullishness over SASE, or course. A key one is the predicted rise in the "digital enterprise", characterized in the report by:
- More user work performed off of the enterprise network than on the enterprise network
- More workloads running in IaaS than running in the enterprise data center
- More applications consumed via SaaS than consumed from enterprise infrastructure
- More sensitive data located outside of the enterprise data center in cloud services than inside
- More user traffic destined for public cloud services than to the enterprise data center
- More traffic from branch offices heading to public clouds than to the enterprise data center
Although if the current remote work trend persists then it may be necessary to change "branch offices" in the last bullet point to "home offices."
