The emergence of SD-WAN has brought about major advancements in the evolution of networking technology; however, it has also introduced some new security challenges. The SD-WAN market is growing at an impressive rate, with its total value projected to exceed $17 billion by 2025.
What is SD-WAN?
Software-defined wide area networking (SD-WAN) applies the benefits of software-defined networking (SDN) to traditionally hardware-based networking.
How is SD-WAN used?
SD-WAN’s overlay architecture helps to centralize and simplify network management to give greater flexibility to the network. This technology supports a variety of connection types (for example - LTE or MPLS) and offers an easy-to-use interface for managing WAN.
What are the security benefits of SD-WAN?
SD-WAN technology uses encryption to ensure more secure connections between every site in the network without the need for a VPN. What’s more, built-in encryption capabilities mean that only authorized users can get into the network and access connected assets.
Another big plus is that an SD-WAN that has been created with virtual overlays can facilitate the use of micro-segmentation beyond the data center. In other words, traffic can be segmented according to application characteristics and policies.
Finally, SD-WAN technology allows for more granular control so that companies can tell networks how particular kinds of traffic should be handled. This lowers the risk of unwanted or harmful traffic entering the network.
