What is SD-WAN?

SD-WAN, an acronym for Software Defined Wide Area Network, uses intelligent, centrally-controlled software to route network traffic faster from A to B. Widely seen as the next-generation evolution in WAN, it is enabling businesses to make secure, truly far-reaching changes to their networks in a fraction of the time of existing technology.

SD-WAN for Business

Business networks transmit ever-increasing volumes of traffic. Employees expect reliable access to it from anywhere at any time. High volume in-house data, third party apps and expanding cloud services, such as Office 365, AWS and Azure, can easily overload any network. The working environment has changed, and SD-WAN provides the flexibility required to accommodate a mobile workforce.

Multi-level connectivity with single-centre control

An SD-WAN network overcomes all this by using multiple connectivity sources simultaneously to transmit data and traffic. Instead of being tied to any one provider, SD-WAN cherry picks the best available connection method and dynamically routes your traffic through it. You maintain central control, enabling you to set policies and determine traffic priority levels. Everything gets from A to B in the most direct way, vastly improving overall network efficiency.

    Overlay SD-WAN onto your existing network

    SD-WAN technology has already been adopted by many leading multinationals and large public bodies, and is in high demand now from smaller organisations too.

    While there is no one-size-fits-all solution out there, SD-WAN is very flexible. A great advantage of SD-WAN is that it can simply overlay onto your existing system. without any of the disruption that major network upgrades sometimes bring. As a leading ICT provider, Clarion can do this for you, giving you all the benefits of SD-WAN straight away.

    For ultimate network security, we recommend combining SD-WAN with SASE (Secure Access Service Edge), an advanced solution, which gives you physical or Cloud protection at every edge location of your network.
