Providing Secure SD-WAN | Top 3 Global Service Providers


SD-WAN solutions from the best-in-class integrate network availability and security seamlessly, meeting a range of network requirements.

Solutions with advanced features for SD-WAN:

The following is a list of the top three SD-WAN providers and vendors for 2021:

The software-defined wide-area network (SD-WAN) can be praised for combining enterprise and security features in a single network. Although convergence is significant, it is not the most important story.

Recent vendors and solutions have combined networking, security, and artificial intelligence under the SD-WAN umbrella, enabling AI, virtual assistants, and improved management. As a result of these upgrades, SD-WAN is beginning to resemble a standalone networking solution.

Moreover, SD-WAN control is another focal point of multi-cloud enterprise hubs, since it provides IT experts with the hybrid network capabilities and security features necessary for cloud transformation. Whatever the case, SD-WANs are in their infancy when it comes to connecting networks, offering cutting-edge security features, and providing secure Internet access. As a result, we need to explore cloud security and artificial intelligence applications for automating networks.

The SD-WAN industry has grown at a phenomenal pace, and there are few other areas of enterprise IT that are growing so quickly. According to IDC, the SD-WAN market will grow by 40.4% annually until 2022, when it will reach $ 4.5 billion. Researchers at the Dell’Oro Group estimate that the rate of growth will reach 35% each year during the next five years.

SD-WAN allows enterprise subsidiaries to move data and applications using a variety of transport strategies, including MPLS, broadband, and 3G and 4G LTE networks. The speed of data is just going to increase with 5G. Additionally to improving security, simplifying system management, and providing more predictable performance, SD-WAN systems also reduce costs.

It is also interesting to note that SD-WAN is on the shortlist for pretty much all businesses. Because there are so many features available, choosing the right vendor can be challenging.

As for the top SD-WAN vendors (outside of Cisco Systems, which is the number one), here is a list compiled from data from eWEEK, Gartner, IDC, Dell’Oro Group, and other sources.
