Thanks to the relentless rise of cloud computing and remote working, the demand for high-bandwidth wide area network (WAN) links over the past few years has never been so high. Analyst firm Forrester predicts that the public cloud market will grow to $236bn by 2020, increasing by 23% in six years.1 A growth in the use of cloud applications to suit the needs of a mobile workforce has meant that WAN pipes have filled up enormously. Not only that, with companies seeking greater agility and local office autonomy, there is far greater demand to connect work apps to the WAN. All of these factors are putting a strain on organisations and their WANs, and sparking security concerns.

Thanks to the relentless rise of cloud computing and remote working, the demand for high-bandwidth wide area network (WAN) links over the past few years has never been higher.

The strain on connectivity to the WAN can increase organisations’ vulnerability to a cyber-attack. Software-defined WAN (SD-WAN) is a technology that allows organisations to centralise control or intelligently direct their WAN traffic. A security solution that ties into SD-WAN means that organisations can protect their data and ensure that a new approach to networking doesn’t mean greater risk, says Marc Sollars of Teneo.
