Retail and banking technology professionals are keenly aware of the large number of devices that connect to their enterprise's network via Ethernet and Wi-Fi. IT sprawl at each branch adds complexity to network visibility and security, and that complexity means increased risk of a breach. Endpoint security alone, without proper edge security, won't be enough to reduce these risks — and even a next-generation firewall service isn't always enough to secure the perimeter.
As a result, organizations are breached because they fail to detect the threat early enough to respond rapidly and effectively. Traditional security solutions are simply not adequate for the level of visibility and control that are required to mitigate today's threats.
The typical bank IT system, for example, uses multiple financial applications as well as video and voice to enable services such as kiosks for consumers to conference with financial experts miles away.
These branches also need to access financial applications that are hosted in the cloud. Connecting all the bank branches or branch offices of a retail company at a reduced bandwidth cost is the crux of the answer. However, the near-real-time nature of the application puts enormous demands on the network to deliver guaranteed performance without risking the data's security or integrity.
Because of this, enterprises such as finance and retail have begun examining the role of software-defined networking as a best practice for their future IT needs, particularly as it relates to security.
Software-defined wide area networking (SD-WAN) addresses flexibility with transport independence and enables connections over direct Internet broadband as well as multiprotocol label switching (MPLS) circuits and LTE/5G. SD-WAN with multicloud connectivity in particular ha ..
